NO-CONTACT TEST UNIT

The utility model a no-contact electricity measurer, which comprises a measuring mechanism and an operating mechanism; the measuring mechanism is composed of a measuring probe (1) and a measuring rod (3); the operating mechanism is composed of a signal amplifier IC and a power amplifier FD. The signal input wire (17) of the measuring mechanism is connected with a shielded antenna (4); the signal input wire of the measuring mechanism is inserted in the antenna socket CZ-[1] of the operating mechanism through an antenna plug (5); after measuring signals are input the operating mechanism, sound and light are generated; the aim of judging the breakpoints of lines is achieved. The electricity measurer has the advantages of little power expenditure, simple structure, safe operation, fast measuring speed and accurate measuring speed. The electricity measurer is suitable for measuring the breakpoints of light and dark lines. The utility model is also suitable for load circuits, transmission and distribution circuits and communication circuits.
