Technical Field
The utility model relates to an electrical technology field specifically is a multi-mode non-contact test pencil.
Background
The non-contact voltage detection test pencil is a portable and quick test instrument for detecting whether a socket or an electric device has voltage, and is a simple test instrument with relatively high safety degree because the test instrument does not need to be directly contacted with a charged body part.
The existing test pencil is developed from the initial contact type to the latest non-contact type automatic voltage induction at present, and the safety and the intuition are greatly improved under the mode that the voltage is added to the manual sensitivity adjustment and the indicator light is high or low. However, the accuracy and convenience of the method still need to be improved, for example, when the distance between the two wires is short, an operator needs to manually debug the sensitivity to distinguish the null line and the live line more accurately.
