0 to 65°C ambient temperature
OFFSET
ADJUSTMENT
Programmable to ±19.9°. This parameter allows the user to
apply an offset value to the temperature being displayed.

SENSOR BREAK
DETECTION
Open TC or RTD sensor indicated by display flashing oPEn.
All relays and alarm status LEDs go to alarm or non-alarm
state, programmable for each relay individually.
Analog output goes to the programmed sensor break value.
