4.8 Compensating the Probe
You need to compensate the probe whenever connecting it to channels for the first time so as
to match the probe to the input channel. Uncompensated probe may cause deviation or error
to the measurement. To compensate the probe, do the following:
1. First of all, set probe factor on the Oscilloscope to 10×, turn the switch to 10× on the probe,
then connect the probe connector to the oscilloscope input channel and the probe tip to
compensation output terminal;
2. Then execute AUTO
3. Observe the displayed waveform
