Probe-compensation
3.3.1. Power Cord
Caution !
Use only power cords designed for your oscilloscope. Use a power source that delivers 90 to 250 V AC
440 Hz.
The probe switch setting is 10X. To avoid a measurement error,
probe compensation must be done. Especially when the probe
is charged. Connect the probe tip to the CAL 1V output
terminal.
A 1 kHz square wave should be displayed with flat tops. Any
distortion in the left presentation is caused by incorrect probe
compensation.
If overshoot or undershoot is present, turn the screwdriver
adjustment in the probe for a flat-top presentation.
Be sure that the attenuation switch on the probe is set to match
with the probe menu selection in the oscilloscope. This
adjustment remains in effect until changed again.
