*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.
