Described buzzer circuit comprises 220 AC power, K switch, transformer T, rectification circuit, capacitor C 1, C2, C3, mu balanced circuit, pilot lamp and hummer, described 220 AC power are inserted in the supply socket by attaching plug and provide, 220 AC power, K switch, and the elementary winding of transformer T is formed a loop, secondary winding two output terminals of transformer T are connected respectively to two input ends of rectification circuit, capacitor C 1 is connected in parallel between two output terminals of rectification circuit, one output terminal back of rectification circuit connects mu balanced circuit, connect pilot lamp and hummer behind the circuit output end of pressure-stabilizing successively, the other end of hummer is as first test lead, another output terminal of rectification circuit is as second test lead, the anodal termination of described detecting pen, and detecting pen negative pole termination is connected first test lead and second test lead by lead-in wire respectively.

Described pilot lamp adopts light emitting diode.

Described buzzer circuit also comprises capacitor C 2, C3, and capacitor C 2, C3 are connected in parallel on respectively between the output terminal and second test lead of mu balanced circuit.

Described pilot lamp and hummer are fixed on the upper end of shell.

The advantage of the utility model multifunctional adaptive formula loop measuring appliance is: simple in structure; be beneficial to and improve efficient and the accuracy rate that wire harness detects; and because the sound that the hummer in the measuring appliance sends is bigger and line length can self-definedly be regulated; so the placement location of measuring appliance does not need to be subjected to big limitation; and easy operating; the operator does not need frequent movable health in the course of the work; in addition; enterprise's low cost of manufacture; use AC power; environmental protection and further reduced cost, and the manufacturing enterprise of many kinds of discrete type wire harness all is suitable for.
