Shutter Correction

Shutter Correction Introduction
Shutter correction is used to compensate for the non-uniformity of the detector pixels or the non-uniformity caused by other optical interference. When the picture effect is poor, you can perform shutter correction, which is common in situations where the ambient temperature changes rapidly.
Shutter Correction Operation
In the imaging interface, click the return button to perform a non-uniformity correction. During shutter correction, the screen will freeze for a short time, which is normal.

Settings

Setting Emissivity
In order to get more accurate measurement results, you need to set the emissivity according to the target to be measured before each measurement, instead of using the default configuration. Emissivity refers to the ratio of the radiation ability of an object to that of a blackbody at the same temperature, which is relative to the reflectivity of the object. The lower the emissivity, the higher the percentage of energy reflected, and the higher the emissivity, the lower the percentage of energy reflected. For example, human skin emissivity is 0.98 and printed circuit board emissivity is 0.91.
For more emissivity information, you can refer to the quick start guide in the package or inquire from other ways.

Emissivity Setting

1. In the thermal imaging interface, press the center button to display the main toolbar.
2. select the “Settings” icon on the toolbar, and press the center button to enter the settings menu.

Setting Ambient Temperature

1. In the thermal imaging interface, press the center button to display the main toolbar
2. Select the “Settings” icon on the toolbar, and press the center button to enter the settings menu.
3. Select “measurement parameters” in the list, press the confirm key, and then select “ambient temperature” to set ambient temperature.

Setting Distance
Different distances will have different effects on the measurement results. For accurate temperature measurement, the distance information of the object is necessary for compensating for the result.

1. In the thermal imaging interface, click the OK button, and the main menu toolbar will be displayed.
2. In the toolbar, select the “Settings” option and click the OK button to enter “Settings”.
3. Select “measurement” in the list, click the confirm button, and then select “distance” to set the distance.
