SECURED
When you press to save the change, you will see
the message below. The secured setting is stored in
non- volatile memory, and does not change when power
has been off or after a remote interface reset. To exit the
calibration mode, turn the power off and on.
Remote interface operation
To secure the power supply, send the above command with
the same code as used to unsecure. For example,
CAL:SEC:STAT ON, HP003632
To change the security code
To change the security code, you must first unsecure the
power supply, and then enter a new code. Read the security
code rules at “Calibration security” on page 63 before
attempting to secure the power supply.
Front panel operation
To change the security code, first make sure that the power
supply is unsecured. Press after the CAL MODE
message is displayed in the calibration mode, enter the new
security code using the knob and resolution selection keys,
then press .
Changing the code from the front panel also changes the
code as seen from the remote interface.
CAL:SEC:STAT {OFF|ON},<code> Secure or unsecure
the power supply.
