What Is Alarm Hysteresis?
The alarm hysteresis is the difference between the temperature where the alarm output turns ON and the
temperature where it turns OFF.
The default setting is 0.2°C
•
Setting Hysteresis for an Upper-limit
Alarm (Alarm Type 2)
•
Setting Hysteresis for a Lower-limit Alarm
(Alarm Type 3)
Example: Hysteresis = 1 Example: Hysteresis = 1
• Setting Hysteresis for an Upper-limit Lower-limit Alarm (Alarm Type 1)
Example: Hysteresis = 1
Note: The same hysteresis is used for the upper and lower limits of an upper-limit and
lower-limit alarm and an upper-limit and lower-limit range alarm

(Deviation between ON and OFF)
Step 3 Additional Settings as Required
Alarm ON
100°C or higher
Alarm hysteresis:
1°C
If the temperature
decreases, the
alarm output will
turn OFF at 99°C.
ON
Alarm hysteresis:
1°C

Alarm ON
100°C or lower
If the temperature
increases, the
alarm output will
turn OFF at 101°C.

ON
Alarm hysteresis:
1°C
Alarm ON
80°C or lower If the temperature
increases, the
alarm output will
turn OFF at 81°C.
Alarm ON
120°C or higher
Alarm hysteresis:
1°C
If the temperature
decreases, the
alarm output will
turn OFF at 119°C.
