CALibration:SECure:STATe
Syntax
CALibration:SECure:STATe {OFF|0|ON|1|RESET},<code>
This command secures or unsecures the U2741A for calibration. To unsecure the
U2741A, you must provide a security code to prevent accidental or unauthorized
calibrations of the U2741A. Before you can calibrate the U2741A, you must
unsecure it by entering the correct security code.
CALibration:SECure:STATe?
This command queries the secured state of the U2741A.
Parameters
Remarks
– The security code is set to ATU2741A and is secured when the U2741A is
shipped from the factory.
– Unsecuring the U2741A using this command enables the U2741A to be
calibrated.
– The security code is stored in nonvolatile memory, and does not change when
the power has been turned off or after a factory reset (
*RST
command).
– To calibrate the U2741A, use the
CAL:VAL
and
CAL?
commands.
– If you forget your security code, you can use the
CAL:SEC:STAT RESET
,
ATU2741A
to override user-defined security code.
