How To Set The Probe Attenuation Coefficient - PeakTech 1190 Bedienungsanleitung

2. Check the displayed wave forms and regulate the probe till a correct compensation is achieved (see Fig.5
and Fig. 5).
3. Repeat the steps mentioned if necessary.

7. How to Set the Probe Attenuation Coefficient

The probe has several attenuation coefficients, which will influence the vertical scale factor of the oscilloscope.
If it is required to change (check) the set value of the probe attenuation coefficient, press the function menu
button of the channels used, then push down the selection button corresponding to the probe till the correct set
value is shown.
This setting will be valid all the time before it is changed again.
Note: The attenuation coefficient of the probe in the menu is preset to 10X when the oscilloscope
is delivered from the factory.
Make sure that the set value of the attenuation switch in the probe is the same as the menu selection of the
probe in the oscilloscope.
The set values of the probe switch are 1X and 10X (see Fig. 7).
Note: When the attenuation switch is set to 1X, the probe will limit the bandwidth of the
oscilloscope in 5MHz. If it is needed to use the whole bandwidth of the oscilloscope, the
switch must be set to 10X.
