Calibration Overview
This section gives an overview of the calibration features of the power supply.
For more detailed discussion of the calibration procedures, see the Service
Guide.
Calibration Security
This feature allows you to enter a security code to prevent accidental or
unauthorized calibrations of the power supply. When you first receive your
power supply, it is secured. Before you can calibrate the power supply, you
must unsecure it by entering the correct security code.
•The security code is set to “HP003633”* or “HP003634”** when the power
supply is shipped from the factory. The security code is stored in non-
volatile memory, and does not change when power has been off or after a
remote interface reset.
To secure the power supply from the remote interface, the security code
may contain up to 12 alphanumeric characters as shown below. The first
character must be a letter, but the remaining characters can be letters or
numbers. You do not have to use all 12 characters but the first character
must always be a letter.
A _ _ _ _ _ _ _ _ _ _ _ (12 characters)
To secure the power supply from the remote interface so that it can be
unsecured from the front panel, use the eight-character format shown
below. The first two characters must be “H P” and the remaining characters
must be numbers. Only the last six characters are recognized from the front
panel, but all eight characters are required.
To unsecure the power supply from the front panel, omit the “H P” and enter
the remaining numbers as shown on the following pages.
H P_ _ _ _ _ _ (6 characters)
If you forget your security code, you can disable the security feature by
adding a jumper inside the power supply, and then entering a new code.
See the Service Guide for more information.
