2.5 Compensating the Probe (Phase Correction)

Be sure to perform phase correction of the probe first when using a probe to make
measurements.

CAUTION

Do not apply external voltage to the signal output terminal for probe compensation
adjustment. Doing so may damage the internal circuitry.

French

ATTENTION

Ne pas appliquer de tension externe sur la borne de sortie de signal afin d’ajuster
la compensation de sonde. Cela pourrait endommager le circuit interne.

Procedure

Turn ON the power switch.

Connect the probe to the input terminal to which the signal is to be applied.

Connect the tip of the probe to the signal output terminal for probe compensation

adjustment on the front panel of the instrument and to the ground wire to the
functional ground terminal.

Perform auto setup according to the procedures given in section 3.5, “Performing

Auto Setup.”

Insert a flat-head screwdriver to the phase adjustment hole and turn the variable

capacitor to make the displayed waveform a correct rectangular wave.
