*1 When the measurement interval is 100 ms, measured values may fluctuate since power supply frequency
noise is not rejected. In such cases, set the measurement interval to 200 ms or more.
*2 For DC power, set to 20 ms.
*3 When synchronizing time by SNTP, the integral time is set to 100 ms. Also in this case, noise of 10 Hz and its integer
multiples is rejected.
