Analog Programming Interface Voltage Readback Calibration
1. Attach a DVM across the voltage readback lines, Pins B5 and B1(GND).
2. Minimum calibration level
Set the voltage readback lines to approximately 10% of full scale by sending
the command:
CAL:ANAL:5V:READ:VOLT:LEV MIN
3. Enter voltage data
Enter the voltage across the voltage readback lines, read from the external
DVM.
CAL:ANAL:5V:READ:VOLT:DATA <voltage>
4. Maximum calibration level
Set the voltage readback lines to approximately 90% of full scale by sending
the command:
CAL:ANAL:5V:READ:VOLT:LEV MAX
5. Enter voltage data
Enter the voltage across the voltage readback lines, read from the external
DVM.
CAL:ANAL:5V:READ:VOLT:DATA <voltage>
6. Power supply calculates and stores calibration constants.
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. Minimum calibration level
Set the input to the programming lines to approximately 0.5V (10% of full
scale).
Set the power supply to receive 5V analog current programming calibration
data with the command:
CAL:ANAL:5V:PROG:CURR:LEV MIN
3. Enter voltage data
Enter the voltage at the current programming lines, read from the external
DVM.
CAL:ANAL:5V:PROG:CURR:DATA <voltage>
4. Maximum calibration level
Set the input to the programming lines to approximately 4.5V (90% of full
scale).
Set the power supply to receive 5V analog current programming calibration
data by sending the command:
CAL:ANAL:5V:PROG:CURR:LEV MAX
