Calibration Commands
CALibration:DAC:ERRor
This command corrects the differential nonlinearity error of the internal DAC without
an external meter. You must send this command before calibrating the voltage. It takes
about 30 seconds to execute the command.
CALibration:SECure:CODE <new code>
This command enters a new security code. To change the security code, first unsecure
the power supply using the old security code. Then, enter the new code. The
calibration code may contain up to 12 characters over the remote interface but the first
character must always be a letter.
CALibration:SECure:STATe {OFF | ON},<code>
This command unsecures or secures the power supply for calibration. The calibration
code may contain up to 12 characters over the remote interface.
CALibration:SECure:STATe?
This command queries the secured state for calibration of the power supply. The
returned parameter is ''0'' (OFF) or ''1'' (ON).

CALibration:STRing <quoted string>
This command records calibration information about your power supply. For
example, you can store such information as the last calibration date, the next
calibration due date, or the power supply's serial number. The calibration message
may contain up to 40 characters. The power supply should be unsecured before
sending a calibration message.
CALibration:STRing?
This command queries the calibration message and returns a quoted string.
CALibration:VOLTage[:DATA] <numeric value>
This command can only be used after calibration is unsecured and the output state is
ON. It enters a voltage value that you obtained by reading an external meter. You
must first select the minimum calibration level (CAL:VOLT:LEV MIN) for the value
being entered. You must then select the middle and maximum calibration levels
(CAL:VOLT:LEV MID and CAL:VOLT:LEV MAX) for the value being entered.
Three successive values must be selected and entered. The power supply then
computes new voltage calibration constants. These constants are then stored in non-
volatile memory.
