HZ-4000 TDR Cable Fault Locator 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 cable
f: Actual sampling frequency
