Portable megohmmeter R1M-A

for the aeronautical industry

The Model R1M-A is a portable Megohmmeter designed to measure high values of resistance associated with the measurement of insulation resistance. It has six resistance ranges from 1 MΩ full scale to 200 GΩ full scale. Four test voltages of 50, 100, 250, and 500 volts DC are provided (50 V maximum to be used with resistances less than 1 MΩ). Resistance readings are displayed on a 3 1/2 digit LCD.The R1M-A is packaged in a rugged, weather tight case, designed to withstand the wear and tear of industrial and military applications, and has a gasket lid. An internal compartment is provided to store the line cord and a set test cables.
