LCD displays nor. An inverted range is where LRV (Menu 0E) is higher in value than URV
(Menu 0F): the LCD displays inv.

2. Press both buttons simultaneously for more than one second to toggle between

Keylock Level
Controls the access protection level for the device. The factory setting is a local
protection level of 0, which places no restriction on modifying settings locally.
Note:
HART settings override local settings:
• If the HART setting is 0, there are no restrictions, and you cannot change the
protection to a higher level locally.
• If the HART setting is 3, no changes can be made, and this protection level cannot
be changed locally.
• Protection level 1 disables the ability to set a value by pressing two buttons
simultaneously.
• Protection level 2 disables the ability to change a value by stepping it up or down.
• Protection level 3 completely disables all changing of values.
