attenuator
Limited Warranty, Limitation of Liability
Read the Warranty and Limitation of Liability statements
that you find in the ScopeMeter 192/196/199 Users
Manual that is included in the test tool kit shipment. These

IMPORTANT NOTES (field installation only)
For Servicing it is very important that you attached the
registration code sticker on the back of your instrument.
For later reference write your Registration Code (RC .....,
included in the sealed envelope), User Code (UC....
received after registration on the internet), and
ScopeMeter serial number (DM....... on the back of your
instrument) in the boxes below.
Instructions for field installation
The Registration document included in the sealed
envelope provides detailed installation instructions. Prior
to installation you must register at our internet site
www.Fluke.com/ScopeMeter.
Requirements:
•Fluke 192/196/199 ScopeMeter with software version
V03.00 or higher.
Note
Earlier versions of hardware and software can be
upgraded by Fluke authorized service centers.
The service center will ask a fee and will ask you
for the registration number of your MS190 kit.
The upgrade includes a full calibration. Ask your
service center for a quote.
•PC with Windows 95/98 or NT4.0, CD-ROM drive,
RS232 serial port, and Internet access
•Optically insulated serial cable PM9080/001 as included
with S versions ScopeMeter. It is also available as
separate accessory.

MA 190 Accessory Kit
The MA 190 is an optional accessory kit that provides
optimal connectivity in medical and video applications.
Optimal user convenience and application coverage is
obtained when the kit is used with a Fluke 192/196/199
that has the MS 190 installed.
Before use carefully read the WARNING on page 1-1.
The kit contains:
•TR 190-50R, 50 Ohm BNC feed-through terminator for
video and HF measurements (Max. 5 V) . See Fig. 1-1.
•TA 190-50R, 50 Ohm 10:1 attenuator feed-through
terminator for additional dynamic range and offset. See
Fig. 1-1.
•CS 190-1R, 1 Ohm current shunt for sensitive current
and mAs measurements. (Max. 500 mA). See Fig. 2-1.
•Safety designed 50 Ohm BNC cable with isolated plastic
connectors. (1.5 m)
•Female BNC to male 4 mm banana plug adapter
•Two female to female 4 mm banana plug adapters
Note 1
TheCS 190-1R, the TR 190-50R, and the
TA 190-50R are not available as individual
accessory, but only as part of the MA 190 kit.
Note 2
The mAs and extended offset functionality are
available only when the MS 190 software is
installed.

Using the MS190 Function
mAs Measurements
The MS190 allows you to make mAs (milliampere x
seconds) cursors measurements. You can do this on live
waveforms, frozen waveforms (HOLD), recorded
waveforms, and on saved waveforms.
To perform mAs measurements, do the following:
1Connect the current shunt CS190-1R to input A
using the BNC cable (see Figure 2-1)
2Connect the current shunt resistor CS 190-1R to
the current source using the BNC to banana
adapter (see Figure 2-1)

The screen shows :
•Top left reading, A(mA, µA, etc.):
the difference between the current amplitude measured
on the left cursor and measured on the right cursor:
•Top right reading, mAs (As, µAs, etc.):
the integrated current over the time between the
cursors.
12 Highlight the left cursor.
13 Move the left cursor to the
desired position on the waveform.
14 Highlight the right cursor.
15 Move the right cursor to the
desired position on the waveform.
Extended Offset
The MS190 extended offset function enlarges the vertical
trace positioning range for input A and input B to 16
divisions (maximum). This allows you to zoom-in vertically
to study small details of the signal.
To choose the extended offset range for input A do the
following:
1Display the INPUT A key labels.
2Open the INPUT A menu
3(2x) Jump to Offset range.
4Select Extended and accept the
extended offset range

To move the trace:
1Move the trace up or down until
the ground marker hits the top -
or bottom grid line.
When moving down, the following banner will show up:
Figure 2-3. Extended offset banner
When moving up a similar banner shows up.
Oscilloscopes and dynamic range
To prevent waveforms from being distorted, in particular
signals with large very steep edges, the signal should stay
within the dynamic range, just as with any Oscilloscope.
The dynamic range limits are the same as the trace offset
limits given in the section Specifications below.
In practice you must take care when using high time base
speeds when looking at signals that have large very steep
edges. They can be distorted when they jump from
outside the dynamic range directly to the visible area of
the screen.
Figure 2-4 shows a pulse wave within the dynamic range
(left), and a pulse wave that is partially outside the
dynamic range (right). The example, particularly the
16 div trace offset, applies to one of the 4 most sensitive
ranges.
