3.5 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.
This may cause damage to the internal circuitry.
Procedure
1.
Turn on the power switch.
2.
Connect the probe to the input terminal to which the signal is to be applied.
3.
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.
4.
Perform auto setup according to the procedures given in section 4.5, “Performing Auto Setup.
5.
Insert a flat-head screwdriver to the phase adjustment hole and turn the variable capacitor to make
the displayed waveform a correct rectangular wave.
