CAL:VOLT
This command is used to calibrate the output voltage. The command enters voltage value that you obtain from an external
meter. (If you are entering the voltage value, allow time for the DVM to stabilize.) You must first select a calibration level
(CAL:VOLT:LEV) for the value being entered. Two successive values (one for each end of the calibration range) must be
selected and entered. The power supply then computes new voltage calibration constants. These constants are not stored in
nonvolatile memory until saved with the CAL:SAVE command.
Command Syntax
CALibrate:VOLTage[:DATA] <NRf>
Parameters

Examples
CAL: VOLT 322 . 5 MV CAL: VOLT: DATA 3 . 225

CAL:SAVE CAL:STAT
CAL:VOLT:LEV
This command sets the power supply to a calibration point that is then entered with CAL:VOLT[:DATA]. During
calibration, two points must be entered and the low-end point (MIN) must be selected and entered first.
Command Syntax
CALibrate:VOLTage:DATA {MIN|MAX}
Parameters
{ < CRD > | MINimum | MAXimum}

CAL: VOLT: LEV MIN CAL: VOLT: LEV MAX

CAL:VOLT:PROT
This command calibrates the power supply overvoltage protection (OV) circuit. The output voltage must be in calibration
before this procedure is performed. Also, the power supply output must be enabled and operating in the constant voltage
(CV) mode. If present, the optional relay accessory must either be disconnected or set to the off (open) state. The power
supply automatically performs the calibration and stores the new OV constant in nonvolatile memory. CAL:VOLT:PROT
is a sequential command that takes several seconds to complete.

Agilent BASIC Calibration Program
The following program can be run on any controller operating under Agilent BASIC. The assumed power supply address is
5 and calibration password is 6680. If required, change these parameters in the appropriate statements.
Note If you are calibrating models 664x, 665x, or 667x, delete or comment out lines 640 through 670 in the
following calibration program. These program lines are only required when calibrating models 668x.
