How to Adjust the Probe Phase

CAUTION

Do not apply excessive force to the phase adjustment screw.
Doing so may damage the internal variable capacitor.

French

ATTENTION

N’appliquez pas une force excessive sur la vis de réglage de
phase. Cela pourrait endommager le condensateur variable
interne.

1.

Connect the BNC connector of the probe to the input of the

oscilloscope, and connect the probe input to the oscilloscope signal

output terminal for probe compensation adjustment (CAL or COMP

terminal).

2.

Operate the vertical and time scales on the oscilloscope, and

turn the phase adjustment screw with the included adjustment

screwdriver to adjust the observed waveform to the correct

waveform (square wave). Adjust the probe capacitance to match

the input capacitance of the oscilloscope with the variable capacitor

inside the probe.

Correct Waveform

Over Compensation

Inadequate Compensation

3. How to Use
