Indirect detection of digital display voltage measuring pen (also known as induction detection)
1. Induction detection: Touch the INDUCTANCE button, and the metal front end of the test pen is close to the object to be detected (pay attention to approaching, not directly touching) the object to be detected. alternating current.
2. Breakpoint detection: When measuring a wire with a breakpoint, touch the INDUCTANCE button, and the metal front end of the test pen is close to (note that it is close to, not directly touching) the wire, or directly touch the insulation of the wire. layer, if the "high voltage symbol" disappears, this is the breakpoint.
3. Using this function, it is easy to distinguish between zero and phase lines (the distance between lines should be increased when measuring side-by-side lines). Detect microwave radiation and
