Voltage Program Calibration Procedure

TM-XR9B-01XN
1. Disconnect the load from the power supply which is to be calibrated.
2. Connect a voltmeter across the power supply's output terminals.

Figure 4-1 Voltage Calibration Setup

1. Set the power supply for calibration as in
2. Activate calibration mode by sending command CMODE ON or
CMODE 1 to the power supply.
3. Send command VLO; ILO to the power supply. Measure and record
the output shown on the external voltmeter.
4. Send command VHI; IHI to the supply. Measure and record the
output voltage as shown on the external voltmeter.
5. Send the command VDATA <vlo>,<vhi> where <vlo> and <vhi> are
the values read from the voltmeter when the VLO and VHI
commands were sent. When the power supply is calibrated, the low to
high voltage program calibration values are stored as constants.
6. Program the supply at various levels using the VSET command to
confirm that the calibration was successful and that linearity is
observed. See the voltage program accuracy specification in
Appendix A.
7. Turn off calibration mode by sending the command CMODE OFF or
CMODE 0 to the power supply.
