Front Panel Calibration Procedure
TM-XDOP-01XN B–9
Analog Programming Interface Voltage Readback Calibration
1. Attach a DVM across the voltage readback lines, Pins B5 and B1(GND).
2. Enter 5V analog voltage readback calibration menu
Select ANLG V PGM 5V from the calibration menu. Press ENTER.
You will be prompted to set up for output voltage calibration. Press ENTER
when ready.
3. Minimum calibration level
The power supply will automatically set the voltage readback lines to
approximately 10% of full scale.
4. Enter voltage data
Enter the voltage across the voltage readback lines, read from the external
DVM. Press ENTER
5. Maximum calibration level
The power supply will automatically set the voltage readback lines to
approximately 90% of full scale.
6. Enter voltage data
Enter the voltage across the voltage readback lines, read from the external
DVM. Press ENTER.
7. Power supply calculates and stores calibration constants.
8. The menu will go to the 5V analog current programming calibration menu.
Analog Programming Interface Current Programming Calibration
1. Connect the power source across the current programming lines, Pins B4 and
B1(GND). Attach a DVM across the current programming lines as well.
2. Enter 5V analog current programming calibration menu
Select ANLG I PGM 5V from the calibration menu. Press ENTER.
You will be prompted to set up for calibration. Press ENTER when ready.
3. Minimum calibration level
Set the input to the programming lines to approximately 0.5V (10% of full
scale).
4. Enter voltage data
Enter the voltage at the current programming lines, read from the external
DVM. Press ENTER
5. Maximum calibration level
Set the input to the programming lines to approximately 4.5V (90% of full
scale).
6. Enter voltage data
Enter the voltage at the current programming lines, read from the external
DVM. Press ENTER.
