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).

Enable Calibration Mode

 

Action

Display

1.

Reset the unit by selecting Shift, Output, and pressing Enter.

*RST

 

If you are calibration a 3-phase source , make sure that the default phase 1

 

 

(φ1) annunciator is lit. Press Phase Select to select a different phase.

 

2.

Press Shift Calibration, scroll to CAL ON, and press Enter.

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.)
