5 tricky features of the indicator screwdriver that many people don’t know about

An indicator screwdriver is an extremely useful thing in the household. Everyone who has used this tool knows about it.

It's time to correct this omission.

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. If not, then most likely already sat down.

2. Grounding check

Using an indicator screwdriver, you can find out if the household appliance has a ground. All you need to do for this is to touch the screwdriver indicator to the equipment. Of course, the household appliance must be turned on. If the diode of the screwdriver lights up, that the equipment does not have a ground or it is somehow not functioning properly.

3. Checking Capacitors and LEDs

It is unlikely that anyone will need this advice at all, but it will definitely not be superfluous to keep in mind in reserve. The fact is that in a similar way, an indicator screwdriver can be used to check capacitors and LEDs. All you need to do is to lean its tip against the positive contact of the miniature device. If the indicator lamp lights up, then everything is in order with the electronics.

4. Check wire for break

It is worth mentioning right away that with the help of an indicator screwdriver it is worth checking the wire for a break only in the most extreme case, when things need to be done right here and now, and the ability to get other equipment or call a specialist is simply no. We touch one contact with a hand, another with a screwdriver. If it glows, then the wire is most likely intact. But this is not accurate, since screwdrivers cannot always correctly recognize the resistance in the wires.
