Damping

Turn Damping on or off with the Damping menu selection.

When damping is on, the Product shows a running

average from ten measurements. The Product makes

approximately three indications per second.

HARTTM Resistor

An internal 250 Ω HART resistor can be enabled when

the Product operates in the mA Measure-24 V mode. This

lets a HART Communicator be connected across the mA

terminals. It is not necessary to add an external resistor.

Note

When the HART resistor is on, the maximum

load-driving capacity is 750

Ω

.

Pump Limits

To prevent overpressure of sensitive devices, the

maximum pressure (pump limit) can be set. When in this

mode, use the arrow softkeys to set the maximum

pressure.

Initial Setup and Basic Pressure

Generation

The Product is supplied with a special low-volume

calibration hose kit for faster pumping to pressure and

quick pressure stabilization. The necessary “quick-fit”

hose connectors and BSP adapter for non-NPT

applications are also included. Fluke recommends that

this type of hose be used to get the best performance

from the Product. When the fittings are installed and the

Product is connected to the unit under test (UUT), the

Product is ready. Figure 3 shows a typical setup.

1. Before pressure is generated, make sure the Product

is configured for the application. If necessary, review

the “Calibrator Interface” section to select the correct

configuration.

2. Make sure that the pressure vacuum knob is set for

the correct function (+ for pressure and – for

vacuum).

hix009.eps

Figure 3. Pump Connection

3. Close the vent knob.

4. Push the pump key and see the pressure (or

vacuum) increase until the necessary pressure is

reached.

Note

The pump motor speed will start slowly when

pressure is low (<15 psi) for better control at low

pressures.

5. Use the fine adjustment vernier to fine tune the

pressure/vacuum indication as necessary.

6. To fully decrease or bleed off the pressure, slowly

turn the vent knob to the open position. When this is

done carefully, the pressure-bleed rate can be

carefully controlled and this helps when taking down-

scale pressure readings.

Electric Pump Considerations

The Product uses a small, battery-powered pneumatic

pump that can quickly build rated high pressure. Because

the pump has an upper pressure generation limit, there

may be atmospheric conditions where it cannot go to full-

scale pressure. High-altitude use (about 3000 ft or

1000 meters), or use at cold temperatures, can limit the

pump to about 90 % of its rated pressure. In these cases,

the vernier adjustment can be used to supply additional

pressure necessary if full-scale pressure must be

supplied.

In these situations, start the calibration with the vernier in

the full counter-clockwise position and then, when the

electric pump reaches its limit, turn the vernier clockwise.

This will raise the pressure to set the necessary reading.

See Figure 3.

Measure Pressure

To measure pressure, connect the Product with the

correct fitting. Select a pressure setting for the display

that is used. The Product has one internal sensor and

many optional external sensors (EPMs) are available.

Make sure to choose the sensor based on working

pressures and accuracy.

Warning

To prevent personal injury:

• Pressure sensors can be damaged

and/or personnel injury can occur due to

improper application of pressure. Refer

to Table 9 for information on

overpressure and burst pressure ratings.

Vacuum should not be applied to any

gauge pressure sensor. The Product

display shows “OL” when an

inappropriate pressure is applied. If “OL”

is shown on any pressure display, the

pressure should be reduced or vented

immediately to prevent Product damage

or possible personnel injury. “OL” is

shown when the pressure exceeds 110 %

of the nominal range of the sensor or

when a vacuum in excess of 2 PSI is

applied on gauge range sensors.

• Push Z to zero the pressure sensor

when vented to atmospheric pressure.

21

Note

To ensure accuracy of the Product, the Product

must be zeroed before a device is calibrated.

See the “Zero Function Use” section.

Media Compatibility

The Product has a unique user-accessible valve cleaning

port for easy pump service. See the “Clean the Valve

Assembly” section for how to clean these valves. Make

sure to only expose the Product to clean, dry gases.

Measure Pressure with External Modules

The Product has a digital interface to be used with

external pressure modules. These modules are available

in different ranges and types that include gauge, vacuum,

differential, and absolute. Connect the modules to the

interface and select [EXT] (external sensor). Since the

interface between the Product and the module is digital,

all accuracy and display resolution is derived from the

module. See Figure 4.

select MEASURE. Current is measured in mA and

percentage of range. The range on the Product is set

to 0 % at 4 mA and 100 % at 20 mA.

For example:

If the current measured is shown as 75 % then the

mA value is 16 mA.

Note

The display shows “OL” when the measured

current is more than the nominal range of

current measurement (24 mA).

2. To source current, the same connections are used.

From the configuration screen, select mA source or

mA Sim-2W.

3. This function will only work on the LOWER screen. In

the source mode, the Product supplies 0 mA to

24 mA with its own internal 24-volt supply, whereas

in the simulate mode the Product acts as a two-wire

transmitter and an external 24-volt supply is

necessary.

4. Push any of the arrow softkeys to start the output

mode and use the arrow softkeys to adjust the mA

output. The function keys can also be used to step

the output in either 25 % steps (4, 8, 12, 16, 20 mA)

or 0 % (4 mA) and 100 % (20 mA). While in the mA

output mode, if the loop is opened or the compliance

is exceeded the display flashes “OL”.

Clean the Product with a soft cloth dampened with water

or water and mild soap.

Clean the Valve Assembly

Occasionally, the Product may not work properly due to

dirt or other contamination of the internal valve assembly.

Use the subsequent procedure to clean the valve

assembly. If this procedure does not correct the problem,

a repair kit can be ordered. See the “User-Replaceable

Parts” section.

1. With a small screwdriver, remove the two valve

retention caps located in the battery compartment

area (see Figure 12).

2. After the caps have been removed, gently remove

the spring and ring assembly.

3. Set aside the valve assemblies in a safe area and

clean out the valve body with a cotton swab soaked

in IPA (isopropyl alcohol).

4. Repeat the process several times with a new cotton

swab each time until there is no evidence of

contamination or dirt.

5. Operate the pump handles several times and

recheck for contamination.

6. Clean the O-ring assembly and the O-ring on the

retention caps with IPA and inspect the O-rings

closely for any damage or excessive wear.

Replacements are included in the repair kit, if

necessary.

7. Inspect the springs for wear or loss of tension. They

should be approximately 8.6 mm long in the relaxed

state. If shorter, they may not provide sufficient seal

tension. Replace if necessary.
