The effect of proper sensor operational temperature calibration was tested by measuring the target at temperatures of +10
and +90 ◦C when the sensor temperature was +49.3 and +12.6 ◦C, respectively.
In Table 2, the measurement performance of different calibrations is shown, when the system temperature is near 10 ◦C
(12.6 ◦C) and the target temperature 90 ◦C.
