The Amprobe AMB-50 industrial high-voltage insulation resistance tester is a digital meter that measures insulation resistance and voltage to help reduce shock hazards and downtime on electrical systems that include wires, cables, transformers, surge arresters, generators, and electrical motors. The tester has automatic range selection for increased safety. The unit measures 0 to 600V alternating current (AC) or direct current (DC) and insulation resistance from 0 to 1 teraohms using 500, 1,000, 2,500, or 5,000V DC test voltage. A low-resistance range (0 to 4,000 ohms) is used to measure resistance in motor windings. The internal memory holds up to 18 test results for later download to a PC using the included USB cord. The tester is safety rated to European Standard (EN) 61010-1, Category III, 600V. The unit has a programmable timer to perform Dielectric Absorption Ratio Tests, Polarization Index (PI) tests, and comparison tests. The tester is powered by eight C batteries (included). The AMB-50 is designed for use by electricians and electrical contractors.
