Calibration Commands

Calibration commands let you enable and disable the calibration mode, change the calibration password, calibrate current and voltage programming, and store new calibration constants in nonvolatile memory. Only one output channel may be calibrated at a time.

NOTE: If calibration mode has not been enabled with CALibrate:STATe, programming the calibration commands will generate an error. You must also save any changes that you made using CALibrate:SAVE, otherwise all changes will be lost when you exit calibration mode.

CALibrate:CURRent

This command initiates the calibration of the current priority mode as well as the 0.5mA current range measurement circuit.

Command Syntax	CALibrate:CURRent[:LEVel] (@<channel>)
Parameters	None	! start current calibration
Examples	CAL:CURR(@1)	! start current calibration
Related Commands	CAL:CURR:LIM,	CAL:CURR:MEAS

CALibrate:CURRent:LIMit[:POSitive]

CALibrate:CURRent:LIMit:NEGative

This command initiates the calibration of the positive or negative current limit.

Command Syntax	CALibrate:CURRent:LIMit[:POSitive] (@<channel>)
	CALibrate:CURRent:LIMit:NEGative (@<channel>)
Parameters	None
Examples	CAL:CURR:LIM (@1)
	CAL:CURR:LIM:NEG (@1)
Related Commands	CAL:CURR	CAL:CURR:MEAS

CALibrate:CURRent:MEASure

This command initiates the calibration of the 0.5A or 15mA current range measurement circuit.

Command Syntax	CALibrate:CURRent:MEASure <NRf>, (@<channel>)
Parameters	A value that falls within the 0.5A or 15mA current range
Unit	A (amperes)
Examples	CAL:CURR:MEAS 0.5,(@1)		!0.5A range
	CAL:CURR:MEAS 0.005,(@1)		!15mA range
Related Commands	CAL:CURR,	CAL:CURR:LIM
