R1M-A Portable Megohmmeter

Brand: Tegam

The Model R1M-A series portable megohmmeter is designed to measure very high values of insulation resistance.

The instrument has six resistance ranges from 1 MegaOhms full scale to 100 GigaOhms full scale, with 100% over range capability.

Four test voltages of 50, 100, 250 and 500 Vdc are provided (50 V maximum to be used with resistances less than 1 MegaOhms).

Resistance readings are displayed on a 3-1/2 digit LCD display with 0.5 inch character height.
