The IR4016-20, IR4017-20, and IR4018-20 ANALOG Megaohm HiTESTERs are single-range megaohm meters designed to improve work efficiency in the field. A sliding cover provides convenient test lead storage, addressing an aspect of meter operation that has been troublesome with conventional designs, while a brightly illuminated meter aids work in dark environments. All three meters’ compliance with the EN 61557-1 and 61557-2 standards makes them ideal for testing electrical facilities and equipment in buildings.
