CAL:STAT
This command enables and disables the calibration mode. The calibration mode must be enabled before the power supply will accept any other calibration commands. The first parameter specifies the enabled or disabled state. The second parameter is the password. It is required if the calibration mode is being enabled and the existing password is not 0. If the second parameter is not entered or is incorrect, an error is generated and the calibration mode remains disabled. The query statement returns only the state, not the password. Note that whenever the calibration mode is changed from enabled to disabled, any new calibration constants are lost unless they have been stored with CAL:SAVE.

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.

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

CAL:VOLT:PROT
This command calibrates the overvoltage protection (OV) circuit. It takes several seconds to complete. The output voltage must be calibrated 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.
