Varec 2920 Installation And Operation Manual page 67

Varec, Inc.
The Administrative PIN locks all setup configuration menus for the 2920. However, it does not
prevent access of the Level Calibration. The User PIN prevents access to Level Calibration.
Using both PINs, you can completely prevent casual access to the 2920.
After the PINs are set, the appropriate PIN window opens depending on the type of data you
are trying to access. For instance, if you are trying to access System Setup information, the
Admin PIN window opens. If you are trying to set a Temperature Offset, the User PIN window
opens.
Administrative PIN
The Administrative PIN is set in the System Data menu. When set, the Admin PIN prohibits
access to all configuration data.
To Set the Admin PIN:
1. Press E to gain access to the menus.
