Classification of voltage test pens
1. Low voltage test pen: used for charged body detection of line voltage 500V and below.
2. Weak current test pen: used for testing electronic products, the general test voltage is 6v--24v. For ease of use, there is often a lead wire with a clip at the end of the electric pen.
3. High voltage test pen: It is used for the operation of 10kv and above projects, and it is the daily testing tool for electricians.
The above is a small knowledge of the measurement range of the test pen, I hope it will be helpful to everyone.
