Using an indicator screwdriver, you can check the presence of a charge in the batteries. You don’t have to do anything complicated: we hold the tool in our hands and apply a battery to it with a negative contact. Press the positive contact of the battery with your finger. If the diode on the screwdriver lights up, then the battery is good.

Why does the indicator screwdriver glow on all wires?
If the switch is on, then the indicator will show the presence of voltage only on the phase contact. If the zero is broken, then the indicator light will be on in the socket on both contacts. It is important to remember that the appearance of any voltage on the neutral wire is dangerous due to the risk of electric shock.
