CALibration:CURRent:PROTection
This command calibrates the overcurrent protection circuit of the power
supply. It takes about 10 seconds to execute the command. The calibration
must be unsecured and the output shorted before calibrating the overcurrent
protection. The power supply automatically performs the calibration and stores
the new overcurrent constant in nonvolatile memory. Notice that current
calibration precedes before sending this command.
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.
