    Cable Finder Fluke 2042Most of the professional electricians very often have to track a cable or a wiring system. Quite often this is a very tiresome and time-consuming job. Besides, very often it is also necessary to determine what protective devices are connected to certain circuits, and to track metal cable conduits, heating lines, or underground cables. Fluke 2042 is a device which helps to cope with these tasks. The kit of route finder Fluke 2042 consists of a generator and a receiver. The generator supplies alternating voltage to the cable. It generates electro-magnetic field around the cable. The receiver has a reel. If it is located near the conductor to which the generator is connected then the lines of magnetic field will be going through the reel in the receiver. This phenomenon is also known as the passing of magnetic field through the circuit. A small voltage generated by the reel is measured by the receiver and is shown on the display. One of the prominent features of Fluke-2042 is the encoded digital signal of the transmitting unit. This ensures a reliable reception of the transmission signal. In this way we avoid false responses which can be caused by the fields generated by interference sources. The kit is also supplied with various appliances and accessories necessary for conducting works. It also has a hard safety plastic case.
