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 in the menu of oscilloscope:
(1) Push the function menu button of the used channels (CH1 or CH2 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.
The set values of the probe switch are 1X and 10X (see Figure 3-9).
