Auto-ranging Portable Ground Resistance and Bond Meter 10 Mω TO 20 Kω The Model R1L-C is a Ground Resistance Ohmmeter designed to measure grounding system resistance as well as soil resistivity, over ranges from 2ω to 20 kω full scale. These resistance measurements correspond to soil resistivity from as low as 2ω-cm to as high as 600,000ω-cm. The R1L-C is capable of Wenner, Fall of Potential, 62% methods as well as bond and continuity measurements. Two, three and four are standard for this instrument.
