Periodically check the resistance value, which must be greater than one megohm. Rotary chisel type electric test pen, the chisel rod is covered with an insulating tube. There is electricity forecast before use to check whether the performance is good.
The test operation should be accurate, and be careful not to touch the double line with the pen tip. The electrical inspection is performed on the insulating mat, and the human body must be grounded. Tested under bright light, the neon tube glow is not clear.
