The PPM Instruments R1M-E Gigohmmeter and Insulation Resistance Tester tests at 250V, 500V and 1000V, and measures insulation resistance from 1KΩ to 4000MΩ. The model R1M-E also features a continuity test range with audible beeper for resistances under 40Ω, and a 600 V and an AC/DC voltage range for safety voltage check. The press-to-test button has an associated locking feature for continuous test up to three-minutes eliminating the need to manually hold down the button. Other features include: a large 3 ½ digit LCD easy viewing: the data hold button retains the value on the display when pressed to facilitate correct recording of information, and a low battery indicator appears on the LCD when it is necessary to change batteries. This lightweight, easy-to-use megohmmeter can be used for most commonly performed insulation tests, such as on cables, switch gear, motors, DC generators, power tools and small appliances.
