PROBE COMPENSATION

To obtain an accurate measurement result, the probe must be adjusted correctly before
measurement.
1. Connect the probe to the INPUT terminal and set the control for a normal sweep display.
2. Connect the probe to the CAL terminal on the front panel, and adjust the SWEEP
TIME/DIV control to display a few cycles of the signal output from it.
3. Adjust the trimmer on the probe to obtain the following correct compensation waveform.

TRACE ROTATION COMPENSATION

Rotation from a horizontal trace position can be the cause of measurement errors.
Adjust the controls for a single display. Set the AC-GND-DC switch to GND and TRIG MODE
to AUTO. Adjust the y POSITION control such that the trace is over the center horizon-
tal graticule line. If the trace appears to be rotated from horizontal, align it with the center
graticule line using the TRACE ROTATION control located on the front panel.

DC VOLTAGE MEASUREMENTS

This procedure describes the measurement procedure for DC waveforms.
Procedure:
1. Connect the signal to be measured to the INPUT jack. Set the vertical MODE to the
channel to be used. Set the VOLTS/DIV and SWEEP TIME/DIV switch to obtain a nor-
mal display of the waveform to be measured. Set the VARIABLE control to the CAL
position.
2. Set the TRIG MODE to AUTO and AC-GND-DC to the GND position, which established
the zero volt reference. Using the y POSITION control, adjust the trace position to the
desired reference level position, making sure not to disturb this setting once made.
