Front Panel Calibration
WARNING LETHAL VOLTAGES. Ac sources can supply 425 V peak at their output. DEATH
on contact may result if the output terminals or circuits connected to the output are
touched when power is applied. These procedures must be performed by a qualified
electronics technician or engineer trained on this equipment.
The following procedures assume you understand how to operate front panel keys (see Chapter 4).

CAL ON 0.0
3.
Enter the calibration password from Entry keypad and press Enter. If the
password is correct the Cal annunciator will come on.
If CAL DENIED appears, then an internal switch has been set to prevent the
calibration from being changed. (see the Service Manual.)
If the password is incorrect, an error occurs. If the active password is lost,
the calibration function can be recovered by setting an internal switch that
defeats password protection. (see the Service Manual.)
