If the tester voltage doesn't reach 70% of higher voltage then it will display lower voltage. For example : In a 220V pin/socket, if the current of 154 volt is flowing then the display will show 12, 36, 55 and 110 and not 220V in the LCD screen. You can check if the electric current is flowing in a circuit by placing the tester on top of the wire. This is safe and easy way to find out if the circuit is active or not.
