"0200" means the effective distance between the thermal sensor and the target is within 20cm (7.87" in).
When a Target comes close within 20cm (7.87" in), it triggers the thermal sensor to work.
●
When the distance is set to 0100, the temperature result is the most accurate.
The number of 8190 or 8191, showing in the first line, is the initial value of the distance sensor, which means there is
no obstruction 130cm (51.18" in) in front of the thermal sensor. In this situation, if you block the thermal sensor with
your hand at 20cm (7.87" in) in the front of the thermal sensor, you will see 0200 at the second line (with an error of
about 1 cm (0.39" in)).
If there is no object blocking but a different number flashes in the first line, it means that the distance sensor is
interfered. In this situation, the voice of "Please check again" is repeated. We have to eliminate the interference
