To convert an infrared thermometer Fahrenheit to Celsius, you first need the infrared thermometer to support both Fahrenheit and Celsius displays, the infrared thermometer appears after powering on at the same time as the two symbols indicated by the arrows in the figure below, which indicates that it is able to support both displays.
If the infrared thermometer, when measuring body temperature, in the body temperature number, after the appearance of the arrow in the figure below, after the symbol, then this is the Fahrenheit degree display mode.
To change the display to Celsius C, press and hold the MODE key for about two seconds, as indicated by the arrow in the figure below.
This will automatically convert the display from Fahrenheit to Celsius, and the temperature numbers and symbols will change automatically after the conversion.
The infrared thermometer used in this experience, after this setting, the infrared thermometer in standby, the display above the default display, will also be shown in degrees Celsius.
And when you turn off the computer and restart it, you don't need to reset it to measure again, the temperature it measures is automatically displayed in Celsius after the switch.
Expanded Information:
1. When using an infrared thermometer, take care that the place where the temperature is measured, such as the forehead or ears, must be removed from all obstacles there, including hair or sweat, so as to ensure the accuracy of the measurement.
2, if it is in the air-conditioned house, the temperature of the environment itself is 36 degrees, then the human body for a long time in the air-conditioned house, the measurement of the object meter will be greatly affected. Also pay attention to avoid measuring in an environment where the temperature is higher than the daily temperature or lower than the daily temperature.
3, the product will be used in the process of 0.3 deviation value, 0.3 deviation value for the consumer most of the acceptable.
4, it is recommended that the user in the process of measuring the measurement distance as far as possible to maintain 3 to 5 centimeters, too close or too far away will affect the measurement results of the value.
