NOTICE
 Warming Up
Wait at least 30 minutes after turning the power on before starting
use. The circuit will be unstable immediately after the power is
turned on so the display value may gradually fluctuate.
 Power On Reset
Once the power is turned on, it will take approx. 2 seconds for the
measurement to start. The judgment output will be output after the
response time (average number of times x sampling rate) has elapsed.
