4-6. Calibration by Remote Interface

This chapter is for remoting calibration method by using remote interface.
When you calibrate the power supply under remote interface state, you should not set other command

Instruments Connection

▌

Before calibrating, connect the all devices like <Figure. 4-2>

▌

Set communication state of each measuring instruments .

▌

Warming up the power supply and measuring instruments while 1 hour or more at room

temperature 20℃ ~ 30℃.

Command Procedure for f Remote Calibration

▌

Refer to SCPI commands of "6-6. Calibration command"

▌

You must send the commands as next order, if occurs the errors, remote calibration

is cancelled.

▌

If error is occurred, you must restart remote calibration.

Voltage Calibraton

▌

Send the "OFF" command to electronic load

▌

Send minimum calibration command of the power supply voltage

Sending command

▌

After waiting for minimum 5 minutes more, measure DVM's voltage.

▌

Send measured voltage value.

For examples, if measured voltage value is 0.1234, sends as following

Sending command

▌

Send maximum calibration command of the power supply voltage

Sending command

▌

After waiting for minimum 5 minutes more, measure DVM's voltage

▌

Send measured voltage value.

For examples, if measured voltage value is 30.123, sends as following.

Sending command

- 61 -

CAL:VOLT MIN

CAL:VOLT MAX

CAL:VOLT 30.123

CAL:VOLT 0.1234
