Figure 4-4 Adjusting Probe Factor
3. Conenct the probe to the output terminal for probe compensation on the Oscilloscope, press
AUTObutton, after several seconds, squarewave displays (1kHz, 3Vpp, Peak-to-Peak Value), See Figure 4-5.

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
Over Compensated Correctly Compensated Under Compensated
If the displayed waveform is under-or over-compensated as indicated above, use the adjusting tool with
non-metal handle to adjust the variable capacitor on the probe until correctly compensated waveform
shows.
Warning: To avoid any electric shock when measuring the high voltage with use of the probe, please ensure
the probe wire is perfectly insulated, and do not touch any metal part of the probe while connecting to the
high voltage source.
