Analog
Programming
Interface
0-10V Range
The 0-10V range of the analog programming interface must be calibrated separately.
Follow the procedure exactly as for calibrating the 0-5V range, using the
corresponding 10V menu options. All the analog signals will be scaled by a factor of
2.
Remote Interface Calibration Procedure
Calibration can also be done via front panel. See “Front Panel Calibration
Procedure” on page 183.
Calibration of voltage programming and readback are combined in a single
procedure.
Output
Voltage
1. Set the load to open circuit. Attach a DVM across the output terminals.
2. Minimum calibration level
Set the output voltage to 10% by sending the command:
CAL:OUTP:VOLT:LEV MIN
3. Enter voltage data
Enter the voltage read from the external DVM.
CAL:OUTP:VOLT:DATA
4. Maximum calibration level
Set the output voltage to 90% by sending the command:
CAL:OUTP:VOLT:LEV MAX
5. Enter voltage data
Enter the voltage read from the external DVM.
CAL:OUTP:VOLT:DATA
6. Power supply calculates and stores calibration constants.
Output
Current
1. Set the power supply and load operate at full output. You must ensure the power
supply is operating in current mode during current calibration. Place a shunt on
the load line so that you can measure the current. Attach a DVM across the shunt
2. Minimum calibration level
Set the output current to 10% by sending the command:
CAL:OUTP:CURR:LEV MIN
