Figure 4.1 Voltage Calibration Setup

1.Set the power supply for calibration as in Figure 4.1.

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 Section 1.

7.Turn off calibration mode by sending the command CMODE OFF or CMODE 0 to the power supply.
