Verification and adjustment security
This feature allows the user 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 adjust
the instrument, unsecure it by inputting the correct security code.
•
The security code is set to KY3390 when the instrument is shipped from the factory. The
security code is stored in nonvolatile memory, and it does not change after the instrument is
powered off, Factory Reset (
*RST
command), or Instrument Preset (
SYSTem:PRESet
command).
•
In the event that the initial security code, KY3390, has been changed, and the new security
code word has been lost, use the master security code word, CAL5710. This code word will
always provide access to the calibration mode.
The following SCPI commands enable and disable the calibration mode and allow the user to set a
new security code:
CALibration:SECure:STATe {OFF|ON},<code>
Enables and disables the calibration mode.
CALibration:SECure:CODE <new code>
Creates a new security code word.
CALibration:SECure:STATe?
Queries the calibration security state.
The new security code may contain up to twelve alphanumeric characters. The first character must
be a letter, but the remaining characters may be letters, numbers, or an underscore. It is
unnecessary to use all twelve characters.
