6.6 Security
6.6.1 How the security code works
Security codes prevent accidental or unwanted changes to program settings or
calibrations.
There are three levels of security:
1.
A user can view the main display and diagnostic screens only.
2. A user has access to the Calibration and Hold menus only.
3. A user has access to all menus.
Procedure
1. If a security code has been programmed, pressing a submenu button (see
Section 6.3) causes the security screen shown below to appear.
2. Enter the three digit security code.
If the entry is correct, the requested submenu appears, and you have access to all
the submenus the code entitles you to.
If the entry is wrong, the Invalid code screen appears.
