INITIAL INSPECTION

1. Place the shipping containers on a secure bench and open them,
taking care not to damage the contents.
2. Review the packing list to verify that all equipment was received.
3. Inspect the equipment and report any shipping damage to the
carrier.

Bench Configuration and
Calibration

Before mounting the Model 3095 MV in the field, the Multivariable
Transmitter can be configured on the bench using a personal computer
and the Engineering Assistant (EA) Software.
The EA software provides advanced configuration capabilities,
including flow parameters such as AIChE fluid, meter tube bore,
differential producer bore, and differential producer material.
After bench configuration, the Model 3095 MV may be bench calibrated.
These procedures include absolute or gage pressure and differential
pressure sensor offset (zero) and slope (span) trim, and RTD
calibration.
For information on bench configuration and bench calibration, see
Bench Configuration (Standard) on page 4-8 and Bench
Calibration Procedure on page 4-9.

Write Protect and Failure
Mode Alarm Jumpers

Once the transmitter has been configured, the configuration data can
be protected by moving the write protect jumper. When this jumper is
installed, the transmitter does not allow any changes to its
configuration memory.
As part of its normal operation, the Model 3095 MV continuously
monitors its own operation. This automatic diagnostic routine is a
timed series of checks repeated continuously. If the diagnostic routine
detects a failure in a transmitter, the transmitter drives its output
either below 3.75 mA or above 21.75 mA depending on the position of
the failure mode jumper.
Both of these jumpers are located on the electronics board just inside
the electronics housing cover (see Figure 2-4). To avoid exposing the
transmitter electronics to the plant environment after installation, set
these jumpers during the commissioning stage on the bench.
When shipped from the factory, the write protect jumper is set to “OFF,”
and the alarm jumper is set to “High” unless specified differently by
ordering the C2 (Custom Configuration) Option Code.

Failure Mode Alarm vs.
Saturation Output Values

2-4

The failure mode alarm output levels differ from the output values that
occur when applied pressure is outside the range points. When pressure
is outside the range points, the analog output continues to track the
input pressure until reaching the saturation value listed below; the
output does not exceed the listed saturation value regardless of the
applied pressure. For example, for pressures outside the 4–20 range
points, the output saturates at 3.9 mA or 20.8 mA. When the
transmitter diagnostics detect a failure, the analog output is set to a
specific alarm value that differs from the saturation value to allow for
proper troubleshooting.

Use the following steps to change the jumper settings:

Explosions can cause death or serious injury. Do not
remove the instrument cover in explosive atmospheres
when the circuit is alive.

1. If the transmitter is installed, secure the loop and remove power.
2. Remove the housing cover opposite the field terminal side.
3. Locate the jumper on the electronics board (see Figure 2-5), then
move the jumper to the desired setting.

Explosions can cause death or serious injury. Both
transmitter covers must be fully engaged to meet explosionproof requirements.

4. Reattach the transmitter cover. To avoid condensation, metal to
metal contact is preferred.
5. If the transmitter is installed, reapply power.

Rosemount Model 3095 MV
The accuracy of a flow or pressure measurement depends on proper
installation of the transmitter and impulse piping. The piping between
the process and the transmitter must accurately transfer the pressure
in order to obtain accurate measurements. Mount the transmitter close
to the process and use a minimum of impulse piping to achieve best
accuracy. Keep in mind, however, the need for easy access, safety of
personnel, practical field calibration, and a suitable transmitter
environment. In general, install the transmitter so as to minimize
vibration, shock, and temperature fluctuations.

GENERAL
CONSIDERATIONS

The following paragraphs discuss the factors necessary for a successful
transmitter installation

The Rosemount Model 3095 MV may be panel-mounted, wall-mounted,
or attached to a two-inch pipe with an optional mounting bracket.
Figure 2-5 illustrates Model 3095 MV mounting configurations, Figure

Taps

Different measurement conditions call for different piping
configurations.

Liquid Flow

For liquid flow measurement, place taps to the side of the line to
prevent sediment deposits, and mount the transmitter beside or below
these taps so gases can vent into the process line.

Gas Flow

For gas flow measurement, place taps in the top or side of the line and
mount the transmitter beside or above the taps so liquid will drain into
the process line.

Steam Flow

For steam flow measurement, place taps to the side of the line, with the
transmitter mounted below them to ensure that the impulse piping
stays filled with condensate.
NOTE
When the transmitter is oriented on its side, the Coplanar™ flange may
be mounted to ensure proper venting or draining. Mount the flange as
shown in Figure 2-7 so that the drain/vent connections are on the
bottom half of the flange for gas service, or on the top half of the flange
for liquid service.

In steam or other elevated temperature services, it is
important that temperatures at the coplanar process flanges
not exceed 185 °F (85 °C).

GAS SERVICE

Inital Checkout and Field Installation

NOTE
In steam service, lines should be filled with water to prevent contact of
the live steam with the transmitter. Condensate chambers are not
needed because the volumetric displacement of the transmitter
is negligible.

Impulse Piping

The piping between the process and the transmitter must accurately
transfer the pressure in order to obtain accurate measurements. In this
pressure transfer, there are five possible sources of error: leaks, friction
loss (particularly if purging is used), trapped gas in a liquid line, liquid
in a gas line, and temperature-induced or other density variation
between the legs.
The best location for the transmitter in relation to the process pipe
depends on the process itself. Consider the following guidelines in
determining transmitter location and placement of impulse piping:
• Keep impulse piping as short as possible.
• Slope the impulse piping at least one inch per foot (8 centimeters
per meter) upward from the transmitter toward the process
connection for liquid.
• Slope the impulse piping at least one inch per foot (8 centimeters
per meter) downward from the transmitter toward the process
connection for gas.
• Avoid high points in liquid lines and low points in gas lines.
• Make sure both impulse legs are the same temperature.
• Use impulse piping large enough to avoid friction effects and
prevent blockage.
• Vent all gas from liquid piping legs.
• When using a sealing fluid, fill both piping legs to the same level.
• When purging is necessary, make the purge connection close to
the process taps and purge through equal lengths of the same size
pipe.
• Avoid purging through the transmitter.
• Keep corrosive or hot (above 250 °F [121 °C]) process material out
of direct contact with the sensor module and flanges.
• Prevent sediment deposits in the impulse piping.
• Keep the liquid head balanced on both legs of the impulse piping.
• Avoid conditions that might allow process fluid to freeze within
the process flange.
NOTE
For steam service, do not blow down impulse piping through the
transmitter. Flush the lines with the blocking valves closed and refill
the lines with water before resuming measurement.

ENVIRONMENTAL
CONSIDERATIONS

Mount the transmitter to minimize ambient temperature changes.
Section 6 Specifications and Reference Data lists the transmitter
temperature operating limits. Mount the transmitter to avoid vibration
and mechanical shock, and to avoid external contact with corrosive
materials.

Rosemount Model 3095 MV

Access Requirements

When choosing an installation location and position, take into account
the need for access to the transmitter.

Process Flange Orientation

The process flanges must be oriented so that process connections can be
made. In addition, consider the possible need for a testing or calibration
input.

Drain/vent valves must be oriented so that process fluid is
directed away from technicians when the valves are used.

Housing Rotation

The electronics housing may be rotated to improve field access to the
two compartments. To rotate the housing less than 90 degrees, release
the housing rotation set screw and turn the housing not more than 90
degrees from the orientation shown in Figure 2-7 on page 2-8. To rotate
the housing greater than 180 degrees, follow steps 1–6 of the
disassembly procedure on page 5-12.

Rotating the housing greater than 180 degrees without
performing the disassembly procedure may damage the
Model 3095 MV sensor module.

Terminal Side of
Electronics Housing

• Wiring connections are made through the conduit openings on the
top side of the housing.
• The field terminal side is marked on the electronics housing.
• Mount the transmitter so that the terminal side is accessible. A
0.75-inch clearance is required for cover removal.
• Install a conduit plug in the unused conduit opening.

Circuit Side of
Electronics Housing

2-10

The circuit compartment should not routinely need to be opened when
the unit is in service; however, provide 0.75 inches clearance if possible
to allow access.

Inital Checkout and Field Installation

Process Considerations

Explosions can cause death or serious injury. Check
transmitter materials of construction and fill fluid for
compatibility with the intended process fluid.

Model 3095 MV process connections on the transmitter flange are 1/4–18
NPT. Flange adapter unions with 1/2–14 NPT connections are available
as options. These are Class 2 threads; use your plant-approved
lubricant or sealant when making the process connections. The process
connections on the transmitter flange are on 21/8-inch (54-mm) centers
to allow direct mounting to a three- or five-valve manifold. By rotating
one or both of the flange adapters, connection centers of 2, 21/8, or 21/4
inches (51, 54, or 57 mm) may be obtained.

Failure to install proper flange adapter O-rings can cause
process leaks, which can result in death or serious injury.
There are two styles of Rosemount flange adapters, each
requiring a unique O-ring, as shown below. Each flange
adapter is distinguished by its unique groove.
MODEL 3051/2024/3001/3095
Flange Adapter

Use only the O-ring designed to seal with the corresponding
flange adapter. Refer to the Spare Parts List on page 6-12
for the correct part numbers of the flange adapters and
O-rings designed for the Model 3095 MV Multivariable
Transmitter.

When compressed, Teflon® O-rings tend to cold flow, which aids in their
sealing capabilities. Whenever flanges or adapters are removed,
visually inspect the Teflon O-rings. Replace them if there are any signs
of damage, such as nicks or cuts. If they are undamaged, they can be
reused. If the O-rings are replaced, the flange bolts may need to be
retorqued after installation to compensate for cold flow. Refer to the
process sensor body reassembly procedure on page 5-16.

ELECTRICAL
CONSIDERATIONS

The signal terminals are located in a compartment of the electronics
housing separate from the transmitter electronics. Figure 2-10
illustrates power supply load limitations for the transmitter.

Power Supply

The dc power supply should provide power with less than 2% ripple.
The total resistance load is the sum of the resistance of the signal leads
and the load resistance of the controller, indicator, and related pieces.
Note that the resistance of intrinsic safety barriers, if used, must be
included.
NOTE
A loop resistance between 250–1100 ohms inclusive is required to
communicate with a personal computer. With 250 ohms of loop
resistance, a power supply voltage of at least 16.5 V dc is required. (1)
If a single power supply is used to power more than one Model 3095 MV
transmitter, the power supply used, and circuitry common to the
transmitters, should not have more than 20 ohms of impedance at 1200 Hz.

NOTE
If the conduit connections are not sealed, mount the transmitter with
the electrical housing positioned downward for drainage. Conduit
should be installed with a drip loop, and the bottom of the drip loop
should be lower than the conduit connections or the transmitter
housing.

Install Grounds

7. Install field wiring ground (optional), and ground the transmitter
case (required).

Field Wiring Ground

a. Field wiring may be grounded at any one point on the signal
loop, or it may be left ungrounded. The negative terminal of
the power supply is a recommended grounding point.

Ground the Transmitter Case

b. The transmitter case should always be grounded in accordance
with national and local electrical codes. The most effective
transmitter case grounding method is direct connection to
earth ground with minimal impedance. Methods for grounding
the transmitter case include:
• External Ground Assembly: This assembly is included with the
transient protection terminal block. The External Ground
Assembly can also be ordered as a spare part (03031-0398-0001).
• Internal Ground Connection: Inside the FIELD TERMINALS
side of the electronics housing is the Internal Ground Connection
screw. This screw is identified by a ground symbol:
.
NOTE
The transient protection terminal block does not provide transient
protection unless the transmitter case is properly grounded. Use the
above guidelines to ground the transmitter case.
Do not run the transient protection ground wire with field wiring as the
ground wire may carry excessive current if a lighting strike occurs.
Grounding the transmitter case using threaded conduit connection may
not provide sufficient ground.

Replace Cover

Explosions can cause death or serious injury. Both
transmitter covers must be fully engaged to meet explosionproof requirements.

8. Replace the cover.

CALIBRATION

After completing the installation, the Model 3095 MV can be field
calibrated. See Field Calibration Procedure on page 4-9 for
recommended field calibration procedures.

FIGURE 3-2. LCD Meter Display.

During Critical Alarm States or Overrange Conditions, the LCD display
alternates between the selected parameters and the critical alarms or
overrange conditions. For more information concerning Fatal Alarm
Messages and Critical Alarm Messages, see Revision 12 and 13
Electronics Board Alarms And Error Conditions on page 5-2.

Totalizer Display

The LCD meter can display flow total as a selected variable. Depending
on the Flow Total Unit selected, the meter will display the
measurement value to a varying decimal point. Table 3-1 shows the
available flow total units and maximum displayable flow total.
The non-volatile totalizer saves flow total information to the permanent
memory of the transmitter. Time between saves to permanent memory
is less than five minutes. In the event of power loss, no more than five
minutes of flow totalization information is unretrievable.

(1) Totalizer display will autoscale flow total reading. Standard display shows flow total to two
decimal places. As flow total increases greater than 1,000,000; the decimal place moves to the
right. At flow totals greater than 100,000,000; the flow total is displayed in exponential notation.
For example, 100,000,000 lb will be displayed as 1.000 E 08

The LCD meter will totalize flow up to a maximum value of 4.29 billion
pounds or the equivalent flow total in other units of measure, after
which it will scroll over to 0 Total Flow. Maximum total flow for
standard volume measurements can be calculated by dividing 4.29
billion pounds or 190 billion kilograms by the standard density. For
example, given a standard density for natural gas of 0.04 lbs/ft3 or
0.68 kg/m3; the maximum total flow value is:
4.29 billion lbs 4 0.04 lbs/ft3 = 107.2 billion SCF

Volumetric Units that is equivalent to 4.29 billion pounds.
Flow Total ≤ 1.100E 12 SCF or
Flow Total ≤ 4.29 billion pounds
Installing the meter on a Model 3095 MV transmitter requires a small
instrument screwdriver and the meter kit (PN 3095-0492-0001 for
Aluminum Housing, PN 3095-0492-0002 for SST Housing).
The meter kit includes:
• one LCD meter assembly
• one extended cover with cover O-ring installed
• two captive screws
• one meter connector (10-pin male-to-male)
NOTE
The LCD Meter requires a Revision 12 or higher electronics board. See
Table E-6 on page E-3 for compatibility information.

3-3

Rosemount Model 3095 MV
Use the following steps to install the meter. See Figure 3-1 for an
illustration.

Explosions can cause death or serious injury. Do not
remove the instrument cover in explosive atmospheres
when the circuit is alive.

1. If the transmitter is installed in a loop, secure the loop and
disconnect power.
2. Remove the transmitter cover opposite the field terminal side.

The circuit board is electrostatically sensitive. Be sure to
observe handling precautions for static-sensitive
components.

3. Note location of security/alarm jumpers. Remove the jumpers and
discard. Insert the meter connector into the ten-pin socket on the
electronics circuit board (see Figure 3-1).
4. Remove the two circuit board captive screws. To do this, loosen
the screws to release the board, then pull out the screws until
they are stopped by the captive thread inside the circuit board
standoffs. Continue unscrewing and remove the two screws; the
circuit board remains.
5. The electronics housing may be rotated to improve field access to
the two compartments. To rotate the housing less than 180
degrees, release the housing rotation set screw and turn the
housing not more than 180 degrees from the orientation shown in
Figure 2-6. To rotate the housing greater than 180 degrees, see
Disassembly Procedures on page 5-12.
NOTE
The meter may be installed in 90-degree increments for easy viewing.
One of the four connectors on the back of the meter assembly must be
positioned to accept the meter connector.

Rotating the housing greater than 180 degrees without
performing the disassembly procedure may damage the
Model 3095 MV sensor module.

6. Decide which direction the meter should be oriented. Insert the
long meter screws into the two holes on the meter assembly that
coincide with the holes on the circuit board.

3-4

Options and Accessories
7. Attach the meter assembly to the circuit board by threading the
screws into captive threads and attaching the meter assembly to
the meter connector. Tighten the meter screws in the standoffs to
secure the meter assembly and electronic circuit board in place.
The meter screws are designed to be captive screws, so they must
first be tightened past the captive thread within the standoffs and
then tightened again to hold the meter/circuit board assembly to
the housing.
8. Check security and alarm jumpers for desired operation. Adjust if
necessary.
9. Attach the extended cover metal to metal.

Explosions can cause death or serious injury. Both
transmitter covers must be fully engaged to meet explosionproof requirements.

Note the following LCD temperature limits:
Operating: –13 to 185 °F (–25 to 85 °C)
Storage:
–40 to 185 °F (–40 to 85 °C)

option, the Model 3095 MV will compensate for both saturated and
superheated steam.

NOTE
DP and Pressure should be selected ONLY if the steam being measured
is always saturated. With this option, the density of the saturated
steam is based on the actual static pressure measurement. This option
also requires that the Model 3095 MV is set to fixed temperature mode.

Gross versus Detail Characterization
The Engineering Assistant calculates the natural gas compressibility
factor using either gross or detail characterization methods. Gross
characterization is a simplified method that is acceptable for a narrow
range of pressure, temperature, and gas composition. Detail
characterization covers all pressure, temperature, and gas composition
ranges for which A.G.A. computes compressibility factors. Table 4-6
identifies the acceptable ranges for both of these characterization
methods.
NOTE
A.G.A. Report No. 8 specifies that it is only valid for the gas phase. The
Detail Characterization method allows water, n-Hexane, n-Heptane,
n-Octone, n-Nonane, and n-Decane to be present up to the dew point.
When entering these component values, be sure that these components
have not reached their respective dew points.

Using the Model 3095 MV Engineering Assistant
Transmitter
HART Output
Burst Mode

When the Model 3095 MV is configured for burst mode, it provides
faster digital communications from the transmitter to the control
system by eliminating the time required for the control system to
request information from the transmitter.
Burst mode is compatible with use of the analog signal. Because HART
protocol features simultaneous digital and analog data transmission,
the analog value can drive other equipment in the loop while the control
system is receiving the digital information. Burst mode applies only to
the transmission of burst data (see Figure 4-29 below), and does not
affect the way other transmitter data is accessed.
Access to information other than burst data is obtained through the
normal poll/response method of HART communication. The EA or the
control system may request any of the information that is normally
available while the transmitter is in burst mode. Between each burst
message sent by the transmitter, a short pause allows the EA or control
system to initiate a request. The transmitter will receive the request,
process the response message, and then continue “bursting” the data
approximately three times per second.
Burst mode is not compatible with multidropping more than one
transmitter because there is no method to discriminate the data

Process Temperature Mode

This selection specifies the process temperature (PT) mode. It allows
you to enable or disable PT input or to specify automatic backup mode.
To enable process temperature input, select Normal PT Mode. In this
mode, the transmitter uses the external RTD for automatic PT
measurement. In the event of an RTD failure, the transmitter goes into
alarm condition.
To disable process temperature input, select Fixed PT Mode, enter the
desired fixed value, then select OK.
Use the Backup PT Mode selection to specify a value to be used for
temperature in the event the RTD fails or is disconnected. Upon failure,
the transmitter will use this backup value and set a HART status bit
for PT alarm, but will not go into alarm condition. The transmitter
returns to automatic temperature sensor readings when the fail
condition no longer exists.
NOTE
The fixed and backup process temperature ranges are wider than the
actual process temperature range:

LOOP WIRING
• HART protocol communication requires a loop resistance value between
250–1100 ohms, inclusive.
• Check for adequate voltage to the transmitter. (If the computer is
connected and 250 ohms resistance is properly in the loop, a power
supply voltage of at least 16.5 V dc is required.)
• Check for intermittent shorts, open circuits, and multiple grounds.
• Check for capacitance across the load resistor. Capacitance should be
less than 0.1 microfarad.
EA INSTALLATION
• Verify that the install program modified the CONFIG.SYS file.
• Verify computer reboot followed EA installation.
• Verify correct COMM port selected (see page 4-2).
• Verify laptop computer is not in low energy mode
(certain laptops disable all COMM ports in low energy mode).
• Did you install EA software onto Windows NT platform?
• Check if HART driver is loaded and installed.

The Model 3095 MV has both analog and digital alarms. If an alarm or
error condition exists, it will be displayed during communication with
the EA, the HART Communicator, or on the LCD meter display. Some
non-flow error conditions may take up to 2 seconds to display, while
some flow error conditions may take up to 10 seconds to display. View
specific alarm conditions using the EA software.
NOTE
Alarms are not logged or archived. The alarms and error conditions
displayed on the Diagnostics, Error Info screen indicate the current
error status for the Model 3095MV transmitter.

NOTE
For a discussion of critical alarms for previous electronics board and
sensor module revisions, see Appendix D. For previous version
compatibility issues, see Appendix E.

COMMUNICATOR KEYS

The keys of the HART Commuincator include action, function,
alphanumeric, and shift keys

FIGURE A-4. The HART Communicator.

Function Keys

Action Keys

275-011AB

Alphanumeric Keys

Shift Keys

Action Keys

As shown in Figure A-4, the action keys are the six blue, white, and
black keys located above the alphanumeric keys. The function of each
key is described as follows:
ON/OFF Key
Use this key to power the HART Communicator. When the
communicator is turned on, it searches for a transmitter on the 4–20
mA loop. If a device is not found, the communicator displays the
message, “No Device Found. Press OK.”
If a HART-compatible device is found, the communicator displays the
Online Menu with device ID and tag.
Directional Keys
Use these keys to move the cursor up, down, left, or right. The right
arrow key also selects menu options, and the left arrow key returns to
the previous menu.
HOT Key
Use this key to quickly access important, user-selectable options when
connected to a HART-compatible device. Pressing the Hot Key turns
the HART Communicator on and displays the Hot Key Menu.
See Customizing the Hot Key Menu in the HART Communicator
manual for more information.

A-6

Appendix A
Function Keys

Use the four software-defined function keys, located below the LCD, to
perform software functions. On any given menu, the label appearing
above a function key indicates the function of that key for the current
menu. As you move among menus, different function key labels appear
over the four keys. For example, in menus providing access to on-line
help, the HELP label may appear above the F1 key. In menus providing
access to the Online Menu, the HOME label may appear above the F3 key.
Simply press the key to activate the function. See your HART
Communicator manual for details on specific function key definitions.

Alphanumeric and Shift Keys

The alphanumeric keys (Figure A-5) perform two functions: the fast
selection of menu options and data entry.

FIGURE A-5. HART Communicator Alphanumeric and Shift Keys.

Data Entry
Some menus require data entry. Use the alphanumeric and shift keys to
enter all alphanumeric information into the HART Communicator. If
you press an alphanumeric key alone from within an edit menu, the
bold character in the center of the key appears. These large characters
include the numbers zero through nine, the decimal point (.), and the
dash symbol (—).
To enter an alphabetic character, first press the shift key that
corresponds to the position of the letter you want on the alphanumeric
key. Then press the alphanumeric key. For example, to enter the letter
R, first press the right shift key, then the “6” key (see Figure A-6). Do
not press these keys simultaneously, but one after the other.
FIGURE A-6. Data Entry Key Sequence.

A-7

Rosemount Model 3095 MV

Fast Key Sequences

HART fast key sequences provide quick on-line access to transmitter
variables and functions. Instead of stepping your way through the menu
structure using the action keys, you can press a HART fast key sequence
to move from the Online Menu to the desired variable or function. Onscreen instructions guide you through the rest of the screens.

Fast Key Sequence Conventions

The fast key sequences for the Model 275 use the following conventions
for their identification:
1 through 9–Refer to the keys located directly below the dedicated
keypad.
Left Arrow–Refers to the left arrow directional key.

Fast Key Sequence Example

HART fast key sequences are made up of the series of numbers
corresponding to the individual options in each step of the menu
structure. For example, from the Online Menu you can change the
Date. Following the menu structure, press 1 to reach Device Setup,
press 3 for Basic Setup, press 4 for Device Info, press 4 for Date. The
corresponding HART fast key sequence is 1, 3, 4, 4.
HART fast keys are operational only from the Online Menu. If you use
them consistently, you will need to return to the Online Menu by
pressing HOME (F3) when it is available. If you do not start at the Online
Menu, the HART fast key sequences will not function properly.
Use Table A-2, an alphabetical listing of every on-line function, to find
the corresponding HART fast key sequences. These codes are applicable
only to Level Controller and the HART Communicator.

MENUS AND FUNCTIONS

The HART Communicator is a menu driven system. Each screen
provides a menu of options that can be selected as outlined above, or
provides direction for input of data, warnings, messages, or other
instructions.

Main Menu

When the HART Communicator is turned on, one of two menus will
appear. If the HART Communicator is connected to an operating loop,
the communicator will find the device and display the Online Menu (see
below). If it is not connected to a loop, the communicator will indicate
that no device was found. When you press OK (F4), it will display the
Main menu.
The Main menu provides the following options:
• Offline–The Offline option provides access to offline configuration
data and simulation functions.
• Online–The Online option checks for a device and if it finds one,
brings up the Online Menu.
• Transfer–The Transfer option provides access to options for
transferring data either from the HART Communicator (memory)
to the transmitter (device) or vice versa. Transfer is used to move
off-line data from the HART Communicator to the transmitter, or
to retrieve data from a transmitter for off-line revision.
NOTE
Online communication with the transmitter automatically loads the
current transmitter data to the HART Communicator. Changes in online data are made active by pressing SEND (F2). The transfer function
is used only for off-line data retrieval and sending.

A-8

Appendix A
• Frequency Device–The Frequency Device option displays the
frequency output and corresponding pressure output of currentto-pressure transmitters.
• Utility–The Utility option provides access to the contrast control
for the HART Communicator LCD screen and to the autopoll
setting used in multidrop applications.
Once selecting a Main menu option, the HART Communicator provides
the information you need to complete the operation. If further details
are required, consult the HART Communicator manual.

Online Menu

The Online Menu can be selected from the Main menu as outlined
above, or it may appear automatically if the HART Communicator is
connected to an active loop and can detect an operating transmitter.
NOTE
The Main menu can be accessed from the Online Menu. Press the left
arrow action key to deactivate the on-line communication with the
transmitter and to activate the Main menu options.
When configuration variables are reset in the on-line mode, the new
settings are not activated until the information is sent to the
transmitter. Press SEND (F2) when it is activated to update the process
variables of the transmitter.
On-line mode is used for direct evaluation of a particular meter, reconfiguration, changing parameters, maintenance, and other functions.

ALARMS AND ERROR
CONDITIONS FOR
REVISIONS 8, 9, AND 10

The Model 3095 MV provides both analog and digital alarms. If an
alarm or error condition exists in the Model 3095 MV, it will be
displayed during the EA communication with the transmitter and on
the LCD meter. Some non-flow error conditions may take up to 2
seconds to display, while some flow error conditions may take up to 10
seconds to display. View specific alarm conditions using the EA
software.
NOTE
Alarms are not logged or archived. The alarms and error conditions
displayed on the Diagnostics, Error Info screen indicate the alarms
present at the time of command invocation.

Critical Alarms

Critical alarms are the highest priority Model 3095 MV alarms, and
indicate an error that prevents accurate sensor or flow measurements.
The analog output and the digital output respond as indicated
in Table D-1.

Overrange Conditions

Overrange conditions typically indicate an error which indicates that
the sensor or flow measurements have reached an overrange condition
where substitute values are being used.
Table D-2 identifies actions to the analog output and digital output
during these conditions. Blank table cells indicate no action for that
condition. Table D-3 identifies recommended corrective action, and also
identifies affects on the flow calculation during these conditions.
