How to Set the Probe Attenuation Coefficient
The probe has several attenuation coefficients, which will influence the vertical
scale factor of the oscilloscope.
To change or check the probe attenuation coefficient on the menu of
oscilloscope:
(1) Push the function menu button of the used channels (CH1 – CH2 button or
CH1 - CH4 button).
(2) Select Probe in the bottom menu; select Attenu in the right menu, turn the
M knob to select the proper value corresponding to the probe.
This setting will be valid all the time before it is changed again.
Caution:
The default attenuation coefficient of the probe on the instrument is
preset to 10X.
Make sure that the set value of the attenuation switch in the probe is
the same as the menu selection of the probe attenuation coefficient in
the oscilloscope.
