ANALOG EARTH TESTER FT3151 Classic Ground Resistance Tester Using 3-Pole Method with Easy Cord Winding System Overview Earthing or grounding of electrical equipment is essential to maintain safety, protecting lives, as well as prevent damage to equipment. The FT3151 Analog EarthTester uses the AC phase differential system to measure earthing resistance, which assures that accurate measurements are unaffected by earth voltage and auxiliary earthing resistance. New innovate cord winders make clean up a breeze. CAT II 300 V Key Features • - Three-electrode method, Two-electrode method (Simple Measurement) • - Wide measurement range for 0 to 1150 Ω, based on EN standard • - Switchable measurement frequency to reduce the effects of power supply harmonics • - Dramatically faster setup: Comes with improved grounding rods and cord winders Measurement system - AC potentiometer method, Three-electrode method/ two-electrode method (switchable) Measuring frequency: 575 Hz/ 600 Hz Measurement current: Three-electrode method: 15 mA rms or less; Two-electrode method: 3 mA rms or less Open circuit voltage: 50 V AC rms or less
