Even with an overvoltage (c) of several hundred volts, the inspection judgment was "Good", but according to the inspection circuit diagram (Fig. 2) according to an example using the inspection judgment element (Fig. 1) invented this time, the specified value If the (error margin value) is determined to be 2V, the input calculation value (141) is 12V or less, the inspection judgment is "Good", and when it is 13V, the inspection judgment is "Fail". This makes it possible to check the accuracy.Also,
When the inspection input calculation value is 8V or more, the inspection judgment is "Good".
When the voltage reaches 7V (microvoltage), it becomes possible to check the accuracy of υ, which makes the inspection judgment "yes or no".
