Keysight M9182A/M9183A Calibration and Verification Procedure
Calibration
From the Soft Front Panel (SFP), you can read the calibration count, secure and
unsecure the calibration memory, read and edit the calibration message and
perform each step of the calibration process. From the SFP, click the Single button
to place the product in single trigger mode, and then select Tools, Calibration.
This will open a window that shows you the calibration message and calibration
count. It also gives you access to the tools that perform calibration.
The first step is to unsecure the calibration memory. This is necessary in order to
store a new calibration message and to change the DMM’s calibration values.
Calibration Security
The M9182A/83A DMMs have a security code that is stored in non-volatile
memory. This feature allows you to prevent accidental or unauthorized
adjustments of the instrument. Before you can adjust the instrument, you must
unsecure it by entering the correct security code.
When you first receive your instrument, it is secured with the factory default
security code of AGM918X. It is a good practice to change the security code to a
new value when you receive your instrument. The security code must start with a
letter and may contain any combination of up to 12 letters, numbers, or
underscores ( _ ). If you change the security code from its default value, be sure to
record the new code in a secure location in order to use it the next time you do
calibration. If you lose your new code, you will need to contact Keysight support
to receive a temporary security code based on the product’s serial number.
To unsecure the instrument for calibration, enter the security code.
Press Unlock. The CAL UNSECURED message appears.
To unsecure or secure the instrument under program control, see the
documentation on the Calibrate.SecurityEnable method in the IVI driver
documentation.
