Calibration commands
The MVS3 has about 40 computer-generated voltages which substitute for conventional
trimmers. The commands below can be used to recalibrate the unit from the front panel.
There are four sets of calibration registers. The current set is permanently changed when
a calibration command is adjusted, and can be saved in the user set with Command 401.
Recall the user set with Command 400. To recall the factory set, use command 200. If
the batteries have been discharged, these sets have been lost, and a fourth set will be
automatically loaded from ROM.
To perform a calibration, turn calibration ON with 100 COMM +. Then enter the
command number and press COMM again. Use SYMM/BORDER/CLIP controls and +-
to make changes. CLEAR when finished, and turn calibration OFF with 100 COMM - if
you want to prevent accidental recalibration.
