Low Frequency Output Compensation, Factory Vertical Cal,
and Attenuator Compensation adjustment procedures.
1. Slide the cabinet on the instrument and allow a 20Ćminute warm up.
2. Press the
button andset
D
to
.
3. Set the volts/div scale to 1 V.
4. Position the cursors 6 divisions apart, centeredvertically andcheck that
the
D
Volts readout is between 5.96 V and 6.04 V.
NOTE
If the readout in step 4 is within the limits given, stop here. The
calibration is complete.
If the readout is outside the limits, continue with this procedure.
5. Adjust the cursors until the
D
Volts readout is 6 V.
6. Note the cursor display error (are the cursors more or less than six
divisions apart).
