specifications on page 7.
Use Proper Power So rce
Do not operate this probe from a power source that applies more than the voltage
specified.
M st be Gro nded
This probe is grounded by the shell of the BNC connector through the grounding
conductor of the power cord of the measurement instrument. Before making
connections to the input leads of this probe, ensure that the output BNC connector is
attached to the BNC connector of the measurement instrument, and that the
measurement instrument is properly grounded. Whenever it is likely that the ground
protection is impaired, you must make the instrument inoperative and secure it
against any unintended operation.

Definiti ns
Measurement Category II (CAT II)
refers to local-level electrical distribution, such as that provided by a standard wall
outlet or plug-connected equipment. Examples of CAT II measurements would be
household appliances, portable tools, and similar modules.
Measurement Category III (CAT III)
refers to measurements on hard-wired equipment in fixed installations, distribution
boards, and circuit breakers that form part of a building wiring installation. ther
examples are wiring, including cables, bus bars, junction boxes, switches, socket
outlets in the fixed installation, and stationary motors with permanent connections to
fixed installations
ollution Degree 2
refers to an operation environment where normally only dry, non-conductive pollution
occurs. Temporary conductivity caused by condensation can be expected.
Working CAT rating is eq al to that of the lowest rated element
within the test set- p.

WARNING
At the time of powering on the probe, the input leads must not be connected to an item
to be tested. Never operate the probe with the case open.
CAUTION
This probe is used to carry out differential measurements between two points on the
circuit under test. This probe is not designed for electrically insulating the circuit under
test or the measuring instrument.

Inspection Proced re
1. Connect the BNC output connector to the vertical input of the oscilloscope.
2. Power on the probe.
3. Set the attenuation setting on the oscilloscope to match the probe.
4. Connect the input of probe to a function generator. Then select a square-wave
output of 10 V amplitude and 100 kHz frequency.
5. The square-wave will be displayed on the screen of the oscilloscope. This
indicates the probe is working properly.
Note that the oscilloscope should show the same voltage and frequency as
the function generator.
Getting Started
1. Connect the BNC output connector to the vertical input of a general purposed
oscilloscope. The oscilloscope must have a ground referenced.
2. Connect power adapter.
3. Select the proper attenuation ratio. When measuring signals below 3,5 V,
switch the attenuation ratio to x1 in order to get higher resolution and less
noise ratio. For voltages up to 18 V, set the attenuation ratio to x5 and for
voltages up to 35 V set the attenuation ratio to x10.
4. The power indicator LED should turn on.
5. Plug the supplied grips onto the test leads and connect the circuit under test.
Vertical Scale on Oscilloscope
The actual vertical scale of the oscilloscope is equal to the attenuation factor
multiplied by the range of vertical scale selected on the oscilloscope.
For example, with the probe on factor x00 and the oscilloscope on 0.5 V/div, the
real vertical scale is 10 x 0.5 = 5 V/div.
With the probe on x5, the real vertical scale is 5 x 0.5 = 2,5 V/ div.
These values apply when the oscilloscope is set to the typical 1 MΩ impedance
input. When the scope is set to 50 Ω input, the actual vertical scale will be
doubled:
10 V/div for the x10 setting and 5 V/div for the x´5 setting.
