Locking the UTX878
Programming Site Data
You can access the security level in two ways.
From the display screen:
1. Press the [ ] key three times, until the lock in the upper right
corner is highlighted.
2. Press [ENT], and proceed to step 4 below.
From the User Program:
1. Press [ESC]. The UTX878 enters the User Program.
2. Press the [ ] key until USER is bracketed.
3. The menu highlights Set Security. Press [ENT].
4. The screen shows three options:
•
Full Lock, which prevents a user from changing any part of the
display or user program without the appropriate code:
•
Prog Lock, which allows a user to change the display but not to
enter the user program:
•
Unlocked, which allows access to both the display and the user
program.
Scroll to the desired option and press [ENT] twice.
5. Press [ESC] to return to the User Program, or continue pressing
[ESC] to return to the display screen. If you have chosen to fully
lock the UTX878, the screen appears similar to Figure 2-3 below,
with a solid lock in the upper right corner. (For a meter with only
the user program locked, the lock shows a keyhole in the center.)
