Probe Compensation - Elditest GE Série Mode D'emploi

Probe Compensation

Proper compensation of the probe is required to assure amplitude accuracy of the
waveform being measured by matching the probe to the oscilloscopes input
capacitance. Low frequency compensation should be adjusted whenever the
probe is connected to or transferred between oscilloscopes.
Procedure:
Low Frequency (LF):
•
Apply a 1 kHz square wave to
the probe or connect to the
oscilloscope's calibrator
output.
•
Adjust the trimmer located on the
probe body (LF) for a flat topped
square.
