Calibration
E3632A User’s Guide 63
Calibration
This section gives an overview of the calibration features of
the power supply. For more detailed discussion of the
calibration procedures, refer to the Service Guide
(E3632- 90010).
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 “HP003632” 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 _ _ _ _ _ _ (8 characters)
