Probe Compensation

English
When the probe is used for the first time or when the probe compensation
signal does not match that shown in Figure 8, you should compensate the
probe to match the input channel of the oscilloscope. The non-compensated or
poorly compensated probe may cause measurement errors.
The procedures for the probe compensation are as follows:
1. Perform Step 1, 2, 3, and 4 in the above section.
2. Check the waveform displayed on the screen of the oscilloscope and
compare it with the waveforms shown in the figure below.
Overcompensated
3. Use a nonmetallic screwdriver to adjust the low-frequency compensation
adjustment hole on the probe until the waveform is displayed as "Properly
Compensated" in the figure above.
