Power Prowler™

3-In-One DMM/TDR Cable Fault Finder for Energized or Unenergized Cables

The Power Prowler™ multi-function time-domain reflectometry (TDR) cable fault finder can identify faulty cables and has the ability to accurately measure the distance to the fault. The Power Prowler can be used on energized or un-energized cables and is suitable for AC and DC voltages up to 600 volts and incorporates a Live Event Detection function that’s ideal for pinpointing intermittent faults.
The digital multimeter function measures AC and DC voltages, impedance and continuity. A special low impedance function (LoZ) function is available to eliminate ghost voltages caused by EMI interference from associated equipment and drives.
The easy-to-use Power Prowler is supplied with a convenient hanging pouch, cable leads, a range of connectors and has a bright, easy-to-read, full-color screen. Additional optional cable accessories can be ordered separately.
Cable Fault Detection
