Calibration 101
CAL:CURR:MON (Series 668xA/669xA only)
This command sets the power supply to the current monitor (I
MON
) calibration point that is then entered with
CAL:CURR[:DATA]. The output current must be calibrated after CAL:CURR:MON is performed.
Command Syntax CALibrate:CURRent:MONitor
Parameters <NRf+>
Examples CAL: CURR: MON CALibrate: CURRent: MONitor
Query Syntax

Related Commands CAL:CURR[:DATA] CAL:STAT
CAL:PASS
This command enters a new calibration password. The command is active only when the power supply is already in the
calibration mode. Unless it is changed subsequently to shipment, the password is the power supply's four-digit model
number. If the password is set to 0, password protection is removed and
CAL:STAT ON is unrestricted. A new password is
automatically stored in nonvolatile memory and does not have to be stored with the
CAL:SAVE command.

CAL:CURR CAL:VOLT CAL:STAT
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.
Whenever the calibration mode is changed from enabled to disabled, any new calibration constants are lost unless they have
been stored with CAL:SAVE.
