Features: 1.Many Test Methods : multi-pulse, voltage sampling, current sampling,LV pulse, etc to maximize customer’s satisfaction. 2.Multi sampling frequency 30M 60M 120M,more accuracy. 3.Long test distance up to 165Km.The voltage is 35kv.4.Test impulse: 0.2~9.9μs, adjustable.5.Error: Relative error under rough test: no more than ±0.25%Absolute error under rough test: under 2KM cable wire: within 1m under 5KM cable wire: within 2m No error after locate.6. Shortest test distance (blind area): ≤2V/f (m)V:The spread speed of ?the waves propagation in the cablef: Actual sampling frequencyTechnical Data: Reading resolution: V/2f(m), resolution<0.5mThe test instruments preset 4 cable&current spread speed.Preset four transmitting speeds of cables, test more easy, fast and accuracy. Adopt double cursor, automatically locating cable faults and display the distance from the fault point. ?8.4 inch touch screen, direct display,and more convenient operation.64digits crash-proof waveform processing system.With micro-printer, higher test accuracy.COM/USB interface,Connect with PC, easy for managing.Take battery itself, convenient to use.Smaller size, light weight, improved waterproof box,can under bad outdoor condition.With enhancement hardware waveform processing circuit.0.5m<br http://www.electric-test.com/ca...cable-fault-locator.html
