Performance and Calibration Procedures

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	“CAL:LEV P1;*OPC?”
	subsequent commands to ensure that the output is stable.
4.	Set the 3458A multimeter to the 10mA range, measure the output	“CAL:DATA <value>”
	current, and enter the data into the dc source.

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	“CAL:LEV P1;*OPC?”
	subsequent commands to ensure that the output is stable.
4.	Set the 3458A multimeter to the 1mA range, measure the output	“CAL:DATA <value>”
	current, and enter the data into the dc source.
5.	Select the second calibration point. *OPC? prevents processing of	“CAL:LEV P2;*OPC?”
	all subsequent commands to ensure that the output is stable.
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”
