ScopeMeter® Test Tool 190 Series II

Users Manual

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 l eads

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.

6

Safety Information: Read First

• Do not apply more than the rated voltage,

between the terminal s 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 transm itted to the product.

• Do not use exposed metal BNC or banana

plug connectors. Fluke offers cables with
plastic, safety designed BNC connector s
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 instruction s.

• Do not use the product if it operates

incorrectly.

• Do not use the product or i t s accessories in

case of any damage.

• Disable the product or its accesso r ies 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, t est
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. Car ef ully
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 haz ardous live
conductors are exposed.

• The battery door must be closed and locked

before you operate the product.

7

ScopeMeter® Test Tool 190 Series II

Users Manual

• 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 gr ound.

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 t he li ne
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 measur em ents or
shows visible damage.

ALL INPUTS ISOLATED

Figure 5. Measurement Connections

Making Input Connections

To make scope measurements connect the red v ol tage
probe to input A, the blue voltage probe to input B, the
grey voltage probe to input C and the green voltage probe
to input D. Connect the short ground leads of each voltage
probe to its own reference potential (See Figure 6).

For Meter measurements refer to the applicabl e s ection in
this chapter.

 Warning

To avoid electrical shock use the insulation
sleeve (Figure 1 item e)) if you use the probes
without the hook clip or the ground spring.

− To maximally benefit from having
independently isolated floating inputs and to
avoid problems caused by improper use,
read Chapter 6: “Tips”.

− For an accurate indication of the measured
signal, it is necessary to match the probe to
the test tool’s input channel. See section

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.

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.

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.

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.

Chapter 4

Triggering on Waveforms

• 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)

Using Trigger Delay or Pre-trigger

You can begin to display the waveform some time before

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 (pos itive)

Warning

To avoid electrical shock or fire, do not

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

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 secti ons . 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.

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, alw ays use t he
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 ref er ence
contact of multiple probes when groundleads
are connected or short-circuiting any circuitry
via the bare ground ring..
