Value range
from... factory-set ...to
Alarm value (limit for relay and LED)
A measured value is considered to be an alarm if
- present value is larger than alarm value
+ ½ hysteresis and
- has been continuously present for longer than configured under the alarm
suppression time .
An alarm is reset if
- present value is smaller than the alarm value - ½ hysteresis.

Hysteresis
It is used to determine an alarm.
The hysteresis lies symmetrically about the limit value
.
0.4 ... 1.0 ... 99.9°C/°F
Low alarm limit
, together with , is used to limit the value range for the alarm
value .
-350 ... -200 ... 999°C/°F
High alarm limit
, together with , is used to limit the value range for the alarm
value .
-350 ... 500 ... 999°C/°F
