The Correct Way to Use the Physical Test Pen

First, we need to buy qualified test pens in regular stores.

Then, when using a physical stylus, the position of the stylus is important: index finger against the cap end of the stylus, hold the stylus lightly with your thumb, middle and ring fingers to hold it steady, then insert the metal tip into the wall socket panel hole, or in the socket hole of the external power strip.

Last, to judge whether it is electrified, check whether the neon tube in the middle of the test pen glows and if the glow is electrification. If the light of the test pen is not obvious in the daytime or in a place with strong light, you can block the light with your hand and observe carefully.
