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

About the MS 190

The MS 190 software expands the Fluke 190 ScopeMeter

software functionality with mAs measurements, non

interlaced video triggering, smart averaging, adjustable

persistence, variable oscilloscope input sensitivity, and

extended offset. To exploit the full potential of the MS 190

software the MA 190 accessory kit is available.

The MS 190 is either factory installed for specific products,

or can be field installed in the full series of the 190 series

products.

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)

that Input B is turned off.

Only in single channel mode key F3 allows the

T 1/T mAs selection.

5Display the INPUT A key labels.

6Open the Probe on A menu.

7Select Current with the arrow

keys, then press ENTER to jump to

Sensitivity.

8Select for example 1 V/A with the

arrow keys, then accept.

9Display the cursor key labels.

When Voltage is selected in the Probe on A menu, the

F3 label shows mVs (not mAs)

10 Press to highlight . Observe

that two vertical cursors are

displayed.

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.
