Fluke 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 universal Power Adapter

only use line cords that comply with the local
safety regulations.

Note:

To accommodate connection to various line
power sockets, the BC190/808 universal Power
Adapter is 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 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.

• Do not apply more than the rated voltage,

between the terminals or between each
terminal and earth ground.

6

Safety Information: Read First

• 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 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.

• 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.

Fluke 190 Series II

Users Manual

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.

Fluke 190-062, 190-102, 190-104, 190-202, 190-204:
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.

Fluke 190-502:
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 II and 600 Vrms CAT III 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.

Making Input Connections

To make scope measurements connect the red voltage
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 applicable section in
this chapter.

Warning

To avoid electrical shock use the insulation
sleeve (Figure 1 item e)) if you use the probes
without the probe tip 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
‘Calibrating the voltage Probes’ in Chapter 7.

RANGE and MOVE UP/DOWN keys
are now assigned to the indicated
channel.

To assign the RANGE and MOVE up
down keys to multiple channels, keep
one channel key pressed, then press
another channel key.

Tip

To set multiple channels to the same range
(V/div) as, for example, input A, do the following:

− Select the input A measurement function,

probe setting and input options for all
involved channels

− press and hold

− press

− release

Notice that all pressed keys are illuminated now.
The MOVE UP/DOWN key and the RANGE
mV/V key applies to all involved input channels.

Displaying an Unknown Signal with
Connect-and-View™

The Connect-and-View feature lets the test tool display
complex, unknown signals automatically. This function
optimizes the position, range, time base, and triggering
and assures a stable display of virtually any waveform. If
the signal changes, the setup is automatically adjusted to
maintain the best display result. This feature is especially
useful for quickly checking several signals.

To enable the Connect-and-View feature when the test
tool is in MANUAL mode, do the following:

1

MANUAL

AUTO

The bottom line shows the range, the time base, and the
trigger information.

The waveform identifier (A) is visible on the right side of
the screen, as shown in Figure 7. The input A zero icon
at the left side of the screen identifies the ground level of
the waveform.

Perform an Auto Set. AUTO appears at
the top right of the screen, the key
illumination is off.

Making Automatic Scope Measurements

The test tool offers a wide range of automatic scope
measurements. In addition to the waveforms you can
display four numeric readings: R
readings are selectable independently, and the
measurements can be done on the input A , input B, input
C or input D waveform.

To choose a frequency measurement for input A, do the
following:

You can use the average functions to suppress random or
uncorrelated noise in the waveform without loss of
bandwidth. Waveform samples with and without smoothing
are shown in Figure 9.

Select Average factor: Average

64. This averages the outcomes
of 64 acquisitions.

Select Average: Normal (normal
average) or Smart (smart
average, see below)

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.
