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 “To Secure and Unsecure the Instrument for Calibration”, on page 83
for a procedure to enter the security code from the front panel. Use the
CAL:SEC:STAT ON command to enter the security code using the remote
interface.
• The security code is set to AT33520A 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
applying a temporary short inside the instrument as described on the
following page.
