The 1503B Metallic Cable Tester that uses time domain reflectometry (TDR), also known as cable radar, to precisely pinpoint faults or changes in impedance in almost any dual-conductor metallic cable. Generates a 1/2 sine pulse, with selectable pulse widths of 2, 10, 100, or 1000 ns. High-resolution 2 ns pulse permits faults as close as 1 foot to be located. Features include direct distance readout- accuracy to better than 1%, intermittent fault monitor mode, high-resolution LCD display with zoom, menu-driven setup, help mode, rugged portability, and calibrated vertical scale. Self tests and internal calibration routines ensure reliability.
