the utility model provides an integrated test indicates, indicates including the experiment luminous electric elements is equipped with on the handle of experimental tail end the inside of handle is provided with and is used for doing luminous electric elements provides operating voltage's power, one of them end electrode of power with luminous electric elements's a connection foot passes through the wire and connects, the other end electrode of power pass through the wire with the test indicates the curved finger position of front end to be connected, another connection foot of luminous electric elements is connected with a contact wire who is used for external metal object of being surveyed.

Furthermore, a groove is formed in the side wall of the handle, conductive parts are respectively arranged on the inner walls at the two ends of the groove, the conductive part at one end is connected with the light-emitting electric element through a lead, and the part at the other end is connected with the bent finger at the front end of the test finger through a lead; the power supply is arranged in the groove, and two poles of the power supply are respectively contacted with the conductive parts at two ends of the groove.

Furthermore, an opening of the groove is provided with an opening and closing cover.

Preferably, the luminous electric element is an LED lamp bead.

Preferably, the power source is a button cell.

Preferably, the handle is a transparent tube made of transparent material, and the light-emitting electric element is arranged inside the handle

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses it indicates the hand of tail end to test with luminous electrical element and power integration, compared with the prior art, when carrying out the protection against electric shock test, need not additionally carry the great power and other auxiliary fittings of isovolumic of protection against electric shock probe power supply box or universal meter, also saved the lamp pearl when having improved the holistic portability of device, a power supply, carry out loaded down with trivial details connection between each accessory such as wire, the test is saved and is built the preparation time, can come into use immediately after reacing the test site, the test is accomplished to high efficiency, and the efficiency of software testing is improved.
