Tab Description
Change
Password
The integrity of Product calibration is protected by a security password that must be
entered before new calibration constants can be saved to non-volatile memory. The
password also protects the ability to set the date for the internal real-time clock. If
the password has not been entered, the Product is secured.
Once the password is entered, the Product is unsecured. The Product secures itself
when the Setup menus are closed or the product is reset. The Product can be
unsecured at any time over the remote interface with the CAL_SECURE command
and by entering the password. The Product prompts for the password to unsecure
the Product before it can accept new values to be eventually secured. The
password contains 1 to 8 digits and is factory set to
8270 .
To change the password locally:
1. Touch
Setup Menu>Instrument Setup>Instrument Settings>Change
Password . The Product prompts for the current password.
2. Use the numeric keypad to enter the current password.
To change the password over the remote interface use the CAL_PASSWD
command.
Note
If the new password is lost, contact Fluke Calibration
Customer Service. Fluke Calibration will supply a new
password.
