Ground Resistance Testers
Won’t fail even in challenging environments Model 1630 ––Quick and easy use—no earth ground stakes are necessary ––Large, 1.35" (35-mm) jaw opening ––Measures ground resistance from 0.025 to 1500 Ω ––Measures ground leakage and load current from 0.2 to 30 mA ––High and Low alarming ––Automatic self calibration
Model 1621 ––3-pole fall-of-potential earth testing for basic measurements ––2-pole resistance measurements for added versatility ––Easily capture values with single-button operation ––Ensure accurate measurements with automatic “noise” voltage detection ––Hazardous voltage warning offers increased user protection ––Clearly read and record data with a large, backlit display
