Cable inhomogeneity meter '' P5-8 ''.
Instruments for adjusting and controlling the PTA.The cable inhomogeneity meter "R5-8" has been produced presumably since 1970. Designed for detecting wave impedance inhomogeneities in cables, determining the distance to a defect. Measured distances: 0 ... 2000 m. Time delay range: 0 ... 20 μs. The minimum distance is 0.5 ... 0.6 m. Power supply from an alternating current with a frequency of 50 Hz (400 Hz), a voltage of 220 V or from a built-in power source (battery), which provides continuous operation for 3 hours. Power consumption: 20 VA from AC mains; 4 W from 12.6 V. Dimensions of the device 125x245x270 mm. Weight 5.5 kg.
