To Unsecure for Calibration You can unsecure the power supply for
calibrati on either from the front panel or o ver the remote interface. The power
supply is secured when shipped from the factory, and the security code is set
to “HP003632”.
• Front-Panel Operation:
If the power supply is secured, you will see the above message for one second
by holding the key for 5 seconds when you turn on the power
supply. To unsecure the power supply, press the key after the “CAL
MODE” message is displayed in the calibration mode, enter the security code
using the knob and resolution selection keys, and then press the key.
When you press the key to save the change, you will see the message
below for one second if the security code is correct. The unsecured 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.
Notice that if the security is incorrect, the power supply displays an
"INVALID" message for a second and returns to the code entering mode for
you to enter the correct code.
