MULTIFUNCTIONAL PINPOINTING RECEIVER
The P-900 receiver is used in combination with surge generators for pinpointing faults in power cables with an acoustic method. The P-900 may also accompany low frequency generators in tracing and fault location sets for tracing, determining the burial depth of underground communication lines, identifying places of power cable faults as well as for selecting a cable from a bunch with an inductive method.
P-900 can operate in acoustic and induction modes.
In the acoustic mode, the receiver allows pinpointing power cables faults with a surge wave method.
In the induction mode, the receiver is used for tracing underground cables, determining their burial depth, identifying a correct cable from a bunch, and pinpointing power cable faults with an induction method.
P-900 is equipped with an LCD display with adjustable contrast and backlight, which allows operating the receiver in various lighting conditions.
The display shows the control and signal receiving parameters as well as internal battery charge level.
The receiver is made in the form of a portable multi-function unit which headphones, and an acoustic or inductive sensors are connected to. Such modular design allows transporting and operating the receiver only with the necessary set of accessories, simplifying its daily use.
