LOCAL CALIBRATION (ENCODER & ETHERNET 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, and then press ENTER key to accept the command)
1. Press 0 and ENTER keys simultaneously to get into Calibration mode.
2. Press “CHANNEL” key to select the active channel to be calibrate.
3. Press “VOLT” key to select voltage calibration. Wait till the second row of the LCD displays “LO=”,
enter the measured value from the DMM and press ENTER key.
4. Repeat for “MI=” (middle) and “HI=” (high) level calibration.
5. When “SUCCESS” is displayed, the voltage calibration is finish.
6. Press “CURR” key to select current calibration. Similar to voltage calibration steps.
7. Press “CHANNEL” key to select next channel for calibration if necessary and follow from step 8.
8. Press “OV/TIME” key to select Over-voltage calibration. Wait until “SUCCESS” is displayed. This
procedure is automatically done by the unit itself.
Note: Over voltage calibration can only be performed after voltage calibration is done.
9. Press “UTILITY” (LOCAL) key to save calibration data. Wait until “SUCCESS” is displayed and the
calibration is finished.
10. Press “CLEAR” key to go back to metering mode.
LOCAL CALIBRATION IS NOW COMPLETE.
