9. Optional: Call the preset and check if the rules are efficient.
10. Enable the device scan function such as linear scan to monitor the scene.
Set Thermography Rule
Steps
1. Customize the rule name.
2. Select the rule type to Point, Line, or Area. Then draw a point, line, or area on the interface where the
position to be measured is.
•
Point: Refer to Point Thermography for detailed configuration.
•
Line: Refer to Line Thermography for detailed configuration.
• Area: Refer to Area Thermography for detailed configuration.
3. Configure the temperature measurement parameters.
•
Emissivity: Set the emissivity of the target. The emissivity of the surface of a material is its
effectiveness in emitting energy as thermal radiation. Different objects have different emissivity.
Common Material Emissivity Reference
Refer to
•
Distance: The distance between the target and the device.
•
Reflective Temperature: If there is any object with high emissivity in the scene, check and set the
reflective temperature to correct the temperature. The reflective temperature should be set the
same as the temperature of the high emissivity object.
4. Click 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: The duration time after the target temperature reaches or exceeds the pre-alarm
temperature/alarm temperature.
•
Tolerance Temperature: Set the tolerance temperature to prevent constant temperature change to
affect 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 target temperature 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 the temperature

to search for the target emissivity.
