Probe compensatio
It needs to adjust it when connecting probe to an
input channel for the first time so that probe can be
appropriate to input channel. Probe without
compensation correction can also br ing i
measurement tolerance or error. Please operate
according to following steps for adjustment of
probe compensation
1. To set probe menu attenuation coefficient to
10× and place probe switch to 10× then connect
digital storage oscillograph probe to CH1. Please
guarantee reliable contact to probe. It has to
connect probe end to signal output connector

earth wire connector of probe compensator. It als o
has to power on CH1 and press [AUTO]
3. Adjust variable capacitance on the probe b
