(3) In addition, the reliability verification at this time is to measure the current consumption while varying the voltage to monitor the electrical state, but the current value measured after manually varying and varying the voltage also shows only the instantaneous measured value. There is a limit to increasing the reliability of

(4) And there is a hassle of having to change the voltage and measure the current consumption every time.

(5) Therefore, since the voltage must be manually changed every time the current consumption is measured, the operator's fatigue increases and the concentration decreases, so there are times when the voltage change is wrong or the measured value cannot be properly recognized.
