LOCAL CALIBRATION (IEEE-488.2 OPTION ONLY)
The following steps describe the calibration procedure of the supply via front panel keypads in local mode.
In these procedures, voltages and currents may exceed full-scale value. Take all necessary precautions.
STEPS:
1. Disconnect all loads from the supply.
2. Strap the supply for local sensing.
3. Connect the DMM to the +S and -S rear terminals as in figure 5.1 for CV calibration and figure 5.2 for
CC calibration.
4. Turn on the power supply.
5. Press RELAY key first (locate at the front panel keypad) and will show:
(ONLY APPLY TO UNITS WITH ISOLATION RELAY FUNCTION)
1-CLOSE 2-REVERSE
ENTER/CLEAR TO EXIT
Press 1
to select “Close” parameter, then press ENTER key to accept the command.
6. FOLLOW CV MODE CALIBRATION STEP BELOW:
(Due to adjusting Calibration to test Low, Mid, High Count Functions)
Press 0 and ENTER keys simultaneously to get into Calibration mode.
