15mA Range Current Measurement Calibration
Action Program Commands
1. Jumper the High sense terminal to the High output terminal.
Jumper the Low sense terminal to the Low output terminal.
Connect the current input of the 3458A multimeter directly to
output 1.
2. Select the 15mA range current measurement calibration for output 1.
“CAL:CURR:MEAS 0.015,(@1)”
3. Select the calibration point. *OPC? prevents processing of all
subsequent commands to ensure that the output is stable.
“CAL:LEV P1;*OPC?”
4. Set the 3458A multimeter to the 10mA range, measure the output
current, and enter the data into the dc source.
“CAL:DATA <value>”
Current Priority Mode Programming and 0.5mA Range Measurement
Calibration
Action Program Commands
1. Jumper the High sense terminal to the High output terminal.
Jumper the Low sense terminal to the Low output terminal.
Connect the current input of the 3458A multimeter directly to
output 1.
2. Select current calibration for output 1.
“CAL:CURR (@1)”
3. Select the first calibration point. *OPC? prevents processing of all
subsequent commands to ensure that the output is stable.
“CAL:LEV P1;*OPC?”
4. Set the 3458A multimeter to the 1mA range, measure the output
current, and enter the data into the dc source.
“CAL:DATA <value>”
5. Select the second calibration point. *OPC? prevents processing of
all subsequent commands to ensure that the output is stable.
“CAL:LEV P2;*OPC?”
6. Measure the output current and enter the data into the dc source.
“CAL:DATA <value>”
Saving the Calibration Constants
WARNING: Storing calibration constants overwrites the existing ones in non-volatile memory. If you
are not sure you want to permanently store the new constants, omit this step. The dc
source calibration will then remain unchanged.
Action Program Commands
1. Save all of the calibration constants.
“CAL:SAVE”
2. Exit Calibration mode. (*RST also exits calibration mode)
“CAL:STAT OFF”
