If "NFS" is selected, the associated relay is in the Non-Fail-safe Mode,

i.e., the relay is "normally de-energized".

"L" or "H" selects whether an alarm is HIGH or LOW.

The LCD Display shows the % O2 in monitor (RUN) mode, alarm

settings during the configuration mode and calibration values during

SPAN and ZERO operations.
