Calibration

Setup

1. Disconnect the load from the power supply which is to be calibrated.

2. Connect a voltmeter across the power supply’s output terminals.

Calibration

Procedure

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 CMODEOFF or CMODE 0

to the power supply.
