Chapter 4 Calibration Procedures
Calibration Security
Calibration Security
This feature allows you to enter a security code to prevent accidental or
unauthorized adjustments of the instrument. When you first receive
your instrument, it is secured. Before you can adjust the instrument, you
must unsecure it by entering the correct security code. See page 60 in
Chapter 3 for a procedure to enter the security code.
• The security code is set to “HP034970” or “AT034972”, depending on
the product number, when the instrument is shipped from the
factory. The security code is stored in non-volatile memory, and does
not change when power has been off, after a Factory Reset (*RST
command), or after an Instrument Preset (SYSTem:PRESet
command).
• The security code may contain up to 12 alphanumeric characters. The
first character must be a letter, but the remaining characters can be
letters, numbers, or an underscore ( _ ). You do not have to use all 12
characters but the first character must always be a letter.
Note: If you forget your security code, you can disable the security feature
by adding a jumper inside the instrument as described on the following
page.
