For use with RG59 (75 Ohms) and RG58 (50 Ohms) or equivalent coaxial cable, this meter provides a direct readout in metres of the length of an un-terminated run of coaxial cable with a resolution of 2-3 metres. A single range of 2.5 to 400 metres on a 4 digit LCD display is provided with automatic indication of open circuit and short circuit conductors. By this means, the location of a short or open circuit in cable runs of up to 800 metres may be found.
