Contact Instrument Solutions


The Fluke 2042 is a professional general purpose cable locator. It is ideal for tracing cables in walls and underground, locating fuses/breakers on final circuits and locating interruptions and short-circuits in cables and electrical floor heating systems. It can also be used for tracing metallic water and heating pipes.

The unit is supplied as a complete kit comprising of a transmitter and receiver in a purpose-made carry case. The receiver also incorporates a torch function for working in dimly lit locations.

Common customer questions & answers

QQuestion How does the Fluke 2042 cable locatorwork?
AAnswer The Fluke cable locator consists of a transmitter and a receiver. The signal generated by the transmitter is a modulated current which generates an electro-magnetic field around the conductor under test (cable pipe etc). This electro-magnetic field induces a voltage within the receiving coil of the receiver. The induced voltage is amplified, decoded, and converted to the original signal by the receiver, and finally displayed on the screen. The connecting parameter for the transmitter during an application must be a closed current circuit.
