Settings

10.1 Measurement Parameters
10.1.1 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.

10.1.2 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.

10.1.3 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.

10.2 Temperature Measurement Mode
The temperature measurement mode: HIGH, LOW and AUTO. Users can choose different temperature measurement ranges to ensure temperature measurement accuracy according to the application conditions.
10.3 High/Low Temperature Alarm
The camera supports the high and low temperature alarm function. The user can set the high and low temperature alarm threshold. The alarm function can be turned on or off by setting the “on” and “off” options. After the high and low temperature alarm is triggered, a prompt icon will appear on the screen. If the “LED alarm” option is turned on, the LED light will flash promptly when an alarm occurs.
For alarm snapshot function, you can set the alarm snapshot time interval and the number of photos taken. Turn on this function, after triggering the high and low temperature alarm, it will take pictures according to the set time interval. When the set number of pictures is reached, the camera will stop taking photos and this function will be turned off automatically. It needs to be turned on again when it is used.
10.4.1 Automatically Save Photos
Turn on this function, the picture will be automatically saved after taking a picture.
10.4.2 Time-lapsed Photo
The camera supports the function of taking pictures at regular intervals, and users can independently set the time interval and number of pictures taken.
