Contact probe compensation
Before making a measurement with the contact probe, check the compensation. Most oscil-
loscopes have a rectangle generator with a 1 KHz testing signal for this purpose. If the com-
pensation is necessary, it can be re-adjusted with the enclosed trim pin on the BNC connector.
Under-compensation
Over-compensation
Correct compensation
Making measurements
Connect the contact probe with the oscilloscope.
Set the attenuation switch to the correct position.
Check the contact probe compensation and adjust it according to the instructions.
The measuring signal should only be applied to the internal conductor. The
external conductor (reference earth) is connected to the earth potential (pro-
tective earth conductor)
• Check the contact probe and its measuring leads for any damage before each measurement.
Never take any measurements if the protecting insulation is defective (torn, missing, etc.).
• To avoid electric shock, do not touch the connections/measuring points directly or indirectly
during measurements.
• Never reach beyond the grip surface of the probes during a measurement process. There is
danger of a life-threatening electric shock.
• Do not use the device shortly before or after a thunderstorm (lightning! / high-power surges!).
Make sure that your hands, shoes, clothing, the floor, the measuring device and/or measuring
lines, circuits and circuit components are always dry.
Cleaning
Before cleaning the device, disconnect it from the oscilloscope.
Live components may be exposed if the covers are opened or parts are re-
moved, unless this can be done manually without tools.
Prior to cleaning or repairing the device, all lines must be detached and the
device must be turned off.
• Do not use scouring, chemical or aggressive cleaning agents such as benzene, alcohol or
such like. These might attack the surface of the device. Furthermore, the fumes are explosive
and hazardous to your health. Moreover, you should not use sharp-edged tools, screwdrivers
or metal brushes or the like for cleaning
• For cleaning the device or the display and the measuring cables, use a clean, slightly damp,
fuzz-free, antistatic cloth.
Disposal
Electronic devices are recyclable material and do not belong in the household waste.
Dispose of an unserviceable product in accordance with the relevant statutory regu-
lations.
