Configuration Password:

The current configuration lock setting is saved.

The CONFIG button is also enabled allowing the operator to open the
configuration menus.
•
When the operator exits the configuration menu, if no changes to the
configuration lock or password parameters were made the configuration lock
is set to its original lock settings; otherwise the latest configuration security
settings is used.
The Read Only, Security & Calibration Locks
There are three additional levels of security once the operator is within the configuration
menu. These limit access to sensitive parameter settings such as calibration, security
settings, and network settings.
If the operator has been given permission to access the configuration menu, the
operator will at a minimum be able to view all the parameters except the security
parameters.
