*1. The response frequency is an average value.
Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object,
and a set distance of half the sensing distance.
*2. Incorrect operation may occur if there is a large temperature difference between the Sensor Head and the Amplifier
Unit.
