EX Series Operating Manual
Current Calibration.
▌Send the "ON" command to electronic load.
▌Send the power supply current minimum calibration command.
Sending command
CAL:CURR MIN
Sending command
▌The mode of electronic load is CC mode, so set the current value is higher than the
power supply's maximum output ampere value. If you send the current calibration
value is lower than the power supply's maximum ampere value, this is CV mode and
wrong calibration value is measured and saved at the power supply. So remind to set
the sending value is higher than power supply's maximum output ampere.
CAL:CURR MIN
▌After waited for minimum 5 minutes more, measures DVM's voltage that is connected
with current monitoring resistor.
▌Send calculated current value that prepared current value calculating program calculated.
For examples, if calculated current value is 0.1234, sends as following.
Sending command
CAL:CURR 0.1234
▌Send the power supply current maximum calibration command.
Sending command
▌After waited for minimum 5 minutes more, measures DVM's voltage that is connected
with current monitoring resistor.
▌Send calculated current value that prepared current value calculating program calculated
CAL:CURR MAX
▌Send calculated current value that prepared current value calculating program calculated.
For examples, if calculated current value is 60.553, sends as following.
Sending command
CAL:CURR 60.553
