Point Please refer to Point Thermography for detailed conguraon.
Line Please refer to Line Thermography for detailed conguraon.
Area Please refer to Area Thermography for detailed conguraon.

Congure the temperature measurement parameters.
Emissivity
Set the emissivity of the target. The emissivity of the surface of a material is its eecveness
in eming energy as thermal radiaon. Dierent objects have dierent emissivity. Refer to
Common Material Emissivity Reference to search for the target emissivity.
Distance
The distance between the target and the device.
Reecve Temperature
If there is any object with high emissivity in the scene, check and set the reecve
temperature to correct the temperature. The reecve temperature should be set the same
as the temperature of the high emissivity object.

and set the Alarm Rule.
Alarm Temperature and Pre-Alarm Temperature
Set the alarm temperature and pre-alarm temperature. E.g., select Alarm Rule as Above
(Average Temperature), set the Pre-Alarm Temperature to 50 °C, and set the Alarm
Temperature to 55 °C. The device pre-alarms when its average temperature is higher than
50 °C and alarms when its average temperature is higher than 55 °C.
Filtering Time
It refers to the
duraon me aer the target temperature reaches or exceeds the pre-alarm
temperature/alarm temperature.
Tolerance Temperature
Set the tolerance temperature to prevent the constant temperature change to aect the
alarm. E.g., set tolerance temperature as 3°C, set alarm temperature as 55°C, and set pre-
alarm temperature as 50°C. The device sends pre-alarm when its temperature reaches 50°C
and it alarms when its temperature reaches 55°C and only when the device temperature is
lower than 52°C will the alarm be cancelled.
Pre-Alarm Output and Alarm Output
When the temperature of target exceeds the pre-alarm or alarm threshold, it triggers the pre-
alarm or alarm output of the connected device.
Area's Temperature Comparison
Select two areas and set the comparison rule, and set the temperature
dierence threshold.
The device alarms when the temperature dierence meets the seng value.
