Solutions
Inaccurate
measurement
1.Check the measurement object. The measurement performance
cannot be guaranteed in the case of forehead blowing, water
dripping, sweating, applying cosmetics, and applying antipyretic
paste;
2. Check the operating environment. Environmental changes have a
greater impact on the measurement. If the environmental
temperature changes too much, or the instrument has just measured
the temperature of an ultra-high object and directly converted to the
measurement of a low-temperature object, the measurement
difference will occur. Leave it for about 10 minutes to obtain a new
test heat balance before using it;
3.The best operating environment of the product is 16 ºC -35ºC ,
check whether the current environmental temperature is too low or
too high.
4.Check the distance of measurement (3-5cm).
Screen

screen displays LO;
2. The temperature of the tested object is higher than 42.9ºC, the
screen displays HI;
3.Check whether the internal parameter settings are disordered.
