6. Use the same method to test the other channels. If the square waveforms actually
shown do not match that in the figure above, please perform “Probe Compensation”
in the next section.
WARNING
To avoid electric shock during the use of probe, please make sure that the
insulated wire of the probe is in good condition and do not touch the metallic
part of the probe when the probe is connected to high voltage source
Probe Compensation
When the probes are used for the first time, you should compensate the probes to match
the input channels of the oscilloscope. Non-compensated or poorly compensated probes
may cause measurement inaccuracy or error. The probe compensation procedures are as
follows.
1. Set the switch to 10X on the probe.
2. Perform steps 1, 2, 3 and 4 of
