The P4i is an easy to use all-in-one solution for troubleshooting, pre-locating and pinpointing of cable faults in complex LV, lighting and control cable networks. Menu guided computerised operation allows to detect and precisely locate various faults for even inexperienced users. Featuring a large colour screen, the P4i can display measurement curves, test results and message codes simultaneously. Integrated TDR capability in combination with the high voltage arc reflection mode (ARTi) will isolate and pre-locate low as well as high resistance faults. The fast HV surge pulse cycles of 3 sec. with up to 1000 Joule @ 4kV support the most demanding locating jobs, DC testing up to 6kV.
