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”
[1]
or “HP003634”
[2]
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.
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.
[1] For Keysight E3633A Model
[2] For Keysight E3634A Model
A _ _ _ _ _ _ _ _ _ _ _ (12 characters)
H P _ _ _ _ _ _ (8 characters)
