4.3.7 Probe Compensation
When used for the first time, the oscilloscope probe must be compensated to match
the input characteristics of the oscilloscope channel to which it is connected. The
non-compensated or poorly compensated probe may cause measurement errors. The
compensation procedure is as follows:
1. Perform Step 1, 2, 3 and 4 in Function Inspection.
2. Check the displayed waveforms and compare them with the waveforms shown in
Figure 4.9 .

3. Use the probe compensation adjustment tool provided in the accessories to adjust
the low-frequency compensation adjustment hole on the probe until the displayed
waveform is consistent with the "Perfectly compensated" waveform shown in the
above figure.
