Warning
To avoid electrical shock or fire:
• Use only the Fluke power supply, Model
BC190 (Power Adapter).
• Before use, check that the selected/indicated
range on the BC190 matches the local line
power voltage and frequency.
• For the BC190/808 and BC190/820 universal
Power Adapters only use line cords that
comply with the local safety regulations.
Note:
To accommodate connection to various line
power sockets, the BC190/808 and BC190/820
universal Power Adapters are equipped with a
male plug that must be connected to a line cord
appropriate for local use. Since the adapter is
isolated, the line cord does not need to be
equipped with a terminal for connection to
protective ground. Since line cords with a
protective grounding terminal are more commonly
available you might consider using these anyhow.
Warning
To avoid electrical shock or fire if a product
input is connected to more than 42 V peak
(30 Vrms) or 60 V dc:
• Use only insulated voltage probes, test leads
and adapters supplied with the product, or
indicated by Fluke as suitable for the Fluke
190 Series II ScopeMeter® Test Tool series.
• Before use, inspect voltage probes, test leads
and accessories for mechanical damage and
replace when damaged.
• Remove all probes, test leads and
accessories that are not in use.
• Always connect the power adapter first to the
ac outlet before connecting it to the product.
• Do not touch voltages >30 V ac rms, 42 V ac
peak, or 60 V dc.
• Do not connect the ground spring (figure 1,
item d) to voltages higher than 42 V peak
(30 Vrms) from earth ground.
• When using the ground reference lead with
any of the probes, make sure that the black
isolation sleeve (Figure 1, item. 10e) is over
the probe tip.
Safety Information: Read First
7
• Do not apply more than the rated voltage,
between the terminals or between each
terminal and earth ground.
• Do not apply input voltages above the rating
of the instrument. Use caution when using
1:1 test leads because the probe tip voltage
will be directly transmitted to the product.
• Do not use exposed metal BNC or banana
plug connectors. Fluke offers cables with
plastic, safety designed BNC connectors
suitable for the ScopeMeter® Test Tool
product, see Chapter 7 ‘Optional
accessories’.
• Do not insert metal objects into connectors.
• Use the product only as specified, or the
protection supplied by the product can be
compromised.
• Carefully read all instructions.
• Do not use the product if it operates
incorrectly.
• Do not use the product or its accessories in
case of any damage.
• Disable the product or its accessories in case
of any damage.
• Keep fingers behind the finger guards on the
probes.
• Use only correct measurement category
(CAT), voltage, and current rated probes, test
leads, and adapters for the measurement.
• Do not exceed the Measurement Category
(CAT) rating of the lowest rated individual
component of a product, probe, or accessory.
• Do not use the product around explosive gas,
vapor, or in damp or wet environments.
• Measure a known voltage first to make sure
that the product operates correctly.
• Examine the case before you use the product.
Look for cracks or missing plastic. Carefully
look at the insulation around the terminals.
• Do not work alone.
• Comply with local and national safety codes.
Use personal protective equipment (approved
rubber gloves, face protection, and
flame resistant clothes) to prevent shock and
arc blast injury where hazardous live
conductors are exposed.
• The battery door must be closed and locked
before you operate the product.
ScopeMeter® Test Tool 190 Series II

• Do not operate the product with covers
removed or the case open. Hazardous voltage
exposure is possible.
• Remove the input signals before you clean
the product.
• Use only specified replacement parts.
Voltage ratings that are mentioned in the warnings are
given as limits for “working voltage”. They represent
V ac rms (50-60 Hz) for ac sinewave applications and as
V dc for dc applications.
Measurement Category IV refers to the overhead or
underground utility service of an installation.
Measurement Category III refers to distribution level and
fixed installation circuits inside a building.
Measurement Category II refers to local level, which is
applicable for appliances and portable equipment.
The terms ‘Isolated’ or ‘Electrically floating’ are used in this
manual to indicate a measurement in which the product
input BNC is connected to a voltage different from earth
ground.
The isolated input connectors have no exposed metal and
are fully insulated to protect against electrical shock.
The BNC jacks can independently be connected to a
voltage above earth ground for isolated (electrically
floating) measurements and are rated up to 1000 Vrms
CAT III and 600 Vrms CAT IV above earth ground.
If Safety Features are Impaired
Use of the product in a manner not specified may impair
the protection provided by the equipment.
Do not use test leads if they are damaged. Examine the
test leads for damaged insulation, exposed metal, or if the
wear indicator shows.
Whenever it is likely that safety has been impaired, the
product must be turned off and disconnected from the line
power. The matter should then be referred to qualified
personnel. Safety is likely to be impaired if, for example,
the product fails to perform the intended measurements or
shows visible damage.
Safe Use of Li-ion battery pack

are shown in Figure 9.
Smart average
In the normal average mode occasional deviations in a
waveform just distort the averaged wave shape, and do
not show up on screen clearly. When a signal really
changes, for instance when you probe around, it takes
quite some time before the new wave shape is stable.
With smart averaging you can quickly probe around, and
incidental waveform changes like a line flyback in video
show up on screen instantly.

The sensitivity range of the mathematical result is equal to
the sensitivity range of the least sensitive input divided by
the scale factor.
Using Mathematics Function Spectrum (FFT)
The Spectrum function shows the spectral content of the
input A, B, C or D waveform in the input waveform color. It
performs an FFT (Fast Fourier Transform) to transform the
amplitude waveform from the time domain into the
frequency domain.
To reduce the effect of side-lobes (leakage) it is
recommended to use Auto windowing. This will
automatically adapt the part of the waveform that is
analyzed to a complete number of cycles
Selecting Hanning, Hamming or no windowing results in a
faster update, but also in more leakage.
Ensure that the entire waveform amplitude remains on the
screen.
To use the Spectrum function, do the following:

Recording Scope Waveforms In Deep
Memory (Scope Record)
The SCOPE RECORD function is a roll mode that logs a long
waveform of each active input. This function can be used
to monitor waveforms like motion control signals or the
power-on event of an Uninterruptable Power Supply
(UPS). During recording, fast transients are captured.
Because of the deep memory, recording can be done for
more than one day. This function is similar to the roll mode
in many DSO’s but has deeper memory and better
functionality.

Analyzing a TrendPlot or Scope Record
From a TrendPlot or Scope Record you can use the
analysis functions CURSORS and ZOOM to perform
detailed waveform analysis. These functions are described
in Chapter 3: “Using Replay, Zoom and Cursors”.
49
Chapter 3
Using Replay, Zoom and Cursors
About this Chapter
This chapter covers the capabilities of the analysis
functions Cursor, Zoom, and Replay. These functions
can be used with one or more of the primary functions
Scope, TrendPlot or Scope Record.
It is possible to combine two or three analysis functions. A
typical application using these functions follows:
• First replay the last screens to find the screen of
special interest.
• Then zoom in on the signal event.
• Finally, make measurements using the cursors.
Replaying the 100 Most Recent Scope
Screens
When you are in scope mode, the test tool automatically
stores the 100 most recent screens. When you press the
HOLD key or the REPLAY key, the memory contents are
frozen. Use the functions in the REPLAY menu to “go back
in time” by stepping through the stored screens to find the
screen of your interest. This feature lets you capture and
view signals even if you did not press HOLD.

The replay bar represents all 100 stored screens in
memory. The icon represents the picture being
displayed on the screen (in this example: SCREEN -51). If
the bar is partly white, the memory is not completely filled
with 100 screens.
From this point you can use the zoom and cursor functions
to study the signal in more detail.

Capturing 100 Intermittents Automatically
When you use the test tool in triggered mode, 100
triggered screens are captured.
By combining the trigger possibilities with the capability of
capturing 100 screens for later replay, you can leave the
test tool unattended to capture intermittent signal
anomalies. This way you could use Pulse Triggering to
trigger and capture 100 intermittent glitches or you could
capture 100 UPS startups.
For triggering, see Chapter 4: “Triggering on Waveforms”.

Chapter 4
Triggering on Waveforms
About this Chapter
This chapter provides an introduction to the trigger
functions of the test tool. Triggering tells the test tool when
to begin displaying the waveform. You can use fully
automatic triggering, take control of one or more main
trigger functions (semi-automatic triggering), or you can
use dedicated trigger functions to capture special
waveforms.
Following are some typical trigger applications:
• Use the Connect-and-View™ function to have full
automatic triggering and instant display of virtually any
waveform.
• If the signal is unstable or has a very low frequency,
you can control the trigger level, slope, and trigger
delay for a better view of the signal. (See next
section.)
• For dedicated applications, use one of the four
manual trigger functions:
• Edge triggering
• Video triggering
• Pulse Width triggering
• External Triggering (models 190-xx2 only)
ScopeMeter® Test Tool 190 Series II

Setting Trigger Level and Slope
The Connect-and-View™ function enables hands-off
triggering to display complex unknown signals.
When your test tool is in manual range, do the following:
MANUAL
AUTO
Perform an auto set. AUTO appears
at the top right of the screen.
Automatic triggering assures a stable display of virtually
any signal.
From this point, you can take over the basic trigger
controls such as level, slope and delay. To optimize trigger
level and slope manually, do the following:
1
TRIGGER
Display the TRIGGER key labels.
2
F2
Trigger on either positive slope or
negative slope of the chosen
waveform.
In Dual Slope Triggering ( X ) the
test tool triggers on both positive
slope and negative slope.
3
F3
Enable the arrow keys for manual
trigger level adjustment.
Figure 28. Screen with all Trigger Information
4 Adjust the trigger level.
Observe the trigger icon that indicates the trigger
position, trigger level, and slope.
At the bottom of the screen the trigger parameters are
displayed (See Figure 28). For example,
means that input A is used as the trigger source with a
positive slope.
When a valid trigger signal is found, the trigger key will be
lit and the trigger parameters appear in black.
When no trigger is found, the trigger parameters appear in
gray, ands the key light will be off.
Triggering on Waveforms
Using Trigger Delay or Pre-trigger 4
59
Using Trigger Delay or Pre-trigger
You can begin to display the waveform some time before
or after the trigger point has been detected. Initially, you
have a half screen (6 divisions) of pre-trigger view
(negative delay).
To set the trigger delay, do the following:
5
MOVE
Hold down to adjust the trigger
delay.
Observe that the trigger icon on the screen moves to
show the new trigger position. When the trigger position
moves left off of the screen, the trigger icon changes into
to indicate that you have selected a trigger delay.
Moving the trigger icon to the right on the display gives
you a pre-trigger view. This allows you to see what
happened before the trigger event, or what caused the
trigger.
In case of a trigger delay, the status at the bottom of the
screen will change. For example:
This means that input A is used as the trigger source with
a positive slope. The 500.0 ms indicates the (positive)
delay between trigger point and waveform display.
When a valid trigger signal is found, the trigger key will be
lit and the trigger parameters appear in black.
When no trigger is found, the trigger parameters appear in
gray, ands the key light will be off.
Figure 29. Trigger Delay or Pre-trigger View
Figure 29 shows an example of a trigger delay of 500 ms
(top) and an example of pre-trigger view of 8 divisions
(bottom).

About this Chapter
This chapter gives you information and tips on how you
can make the best use of the test tool.
Using the Standard Accessories
The following illustrations show the use of the standard
accessories such as voltage probes, test leads, and the
various clips.

Warning
To avoid electrical shock or fire, do not
connect the ground spring to voltages higher
than 30 Vrms from earth ground.
Figure 38. Electronic Connections for Measurements
Using Hook Clips and Alligator Clip Grounding
 Warning
To avoid electrical shock, re-apply the insulation
sleeve (Figure 1, item e) over the probe tip when
the hook clip is not used. This also avoids the
risk of accidently interconnecting the reference
contact of multiple probes when groundleads
are connected or avoids short-circuiting any
circuitry via the bare ground ring of the probe..
Tips
Using the Independently Floating Isolated Inputs 6
83
Using the Independently Floating
Isolated Inputs
You can use the independently floating isolated inputs to
measure signals that are independently floating from each
other.
Independently floating isolated inputs offer additional
safety and measurement capabilities compared to inputs
with common references or grounds.
Measuring Using Independently Floating Isolated
Inputs
The test tool has independently floating isolated inputs.
Each input section (A, B, C, D – A, B, METER INPUT) has
its own signal input and its own reference input. The
reference input of each input section is electrically isolated
from the reference inputs of the other input sections. The
isolated input architecture makes the test tool about as
versatile as having four independent instruments. The
advantages of having independently floating isolated
inputs are:
• It allows simultaneous measurement of independently
floating signals.
• Additional safety. Since the commons are not directly
connected, the chance of causing short circuit when
measuring multiple signals is greatly reduced.
• Additional safety. When measuring in systems with
multiple grounds, the ground currents induced are
kept to a minimum.
Because the references are not connected together inside
the test tool, each reference of the used inputs must be
connected to a reference voltage.
Independently floating isolated inputs are still coupled by
parasitic capacitance. This can occur between the input
references and the environment, and between the input
references mutually (see Figure 39). For this reason, you
should connect the references to a system ground or
another stable voltage. If the reference of an input is
connected to a high speed and / or high voltage signal,
you should be aware of parasitic capacitance. (See Figure
39, Figure 41, Figure 42 and Figure 43.)
Note
The input channels are electrically isolated from
the USB port and from the power adapter input.
ScopeMeter® Test Tool 190 Series II
Users Manual
84
ABCD
Figure 39. Parasitic capacitance between probes,
instrument and environment
Note:
Parasitic capacitances such as shown in Figure
39, 41 and 43 can cause ringing on the signal.
Ringing can be limited by adding a ferrite bead
around the probe cable.
Warning
To avoid electrical shock, always use the
insulation sleeve (Figure 1, item e) or the
hook clip when using the probe reference
(ground) lead. The voltage applied to the
reference lead is also present on the ground
ring near the probe tip as shown in Figure 40.
The isolation sleeve avoids the risk of
accidently interconnecting the reference
contact of multiple probes when groundleads
are connected or short-circuiting any circuitry
via the bare ground ring..

Charging the Batteries
At delivery, the Li-ion batteries may be empty and must be
charged for 5 hours (with the test tool turned off) to reach full
charge.
When battery power is used, the battery indicator at the
top of the screen informs you about the condition of the
batteries. The battery symbols are: . The
symbol indicates that there are typically five minutes
of operating time left. See also Displaying Battery
Information on page 101.
To charge the batteries and power the instrument, connect
the power adapter as shown in Figure 46. To charge the
batteries more quickly, turn off the test tool.
Caution
To avoid overheating of the batteries during
charging, do not exceed the allowable
ambient temperature given in the
specifications.
Note
No damage will occur if the power adapter is
connected for long periods, e.g., during the
weekend. The instrument then automatically
switches to trickle charging.
Figure 46. Charging the Batteries
Alternatively, you may choose to exchange the battery
(Fluke accessory BP290 or BP291) with a fully charged
one, and use the external battery charger EBC290
(optional Fluke accessory).

Calibrating the Voltage Probes
To fully meet user specifications, you need to adjust the
voltage probes for optimal response. The calibration
consists of a high frequency adjustment and a dc
calibration for 10:1 probes and 100:1 probes. The probe
calibration matches the probe to the input channel.
This example shows how to calibrate the 10:1 voltage
probes:

Installing USB Drivers
Introduction
The Fluke 190 Series II ScopeMeter® comes with a USB
interface (connector: USB type “B mini”) for
communication with a computer. To be able to
communicate with the instrument, drivers need to be
loaded onto the computer. This document describes how
to install the drivers on a Windows XP computer.
Installing on other Windows versions will be similar.
Drivers for Windows XP, Vista and Win 7 are available
from the Windows Driver Distribution Center, and can be
downloaded automatically if your computer is connected
to the internet.
The drivers have passed Windows Logo Verification and
are signed by Microsoft Windows Hardware Compatibility
Publisher. This is required for installation on Win 7.
Note
The Fluke 190 Series II instrument requires two
drivers to be loaded in sequence.
− 1st it requires installation of the Fluke 190
ScopeMeter® USB driver
− 2nd it requires installation of the Fluke USB
Serial port
Both of these drivers need to be installed to be
able to communicate with the ScopeMeter®!
