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 51 in Chapter 3 for a procedure to enter the security code.
• The security code is set to “
HP034970” 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.
