RUOSHUI 4106A 4016 Earth Resistance Tester 3-Pole 4-Pole Method Measurement AC True RMS Large LCD Display With LED Backlight Basic features of the product Basic measurement functions Earth resistance measurement (RE) Measurement method: 3-pole method, 4-pole method Measuring range: 0.02Ω～1999Ω Minimum resolution: 0.01 Ω Basic accuracy: 5% Soil resistivity measurement (ρ) Measurement range: 0.01Ω·m～376.8KΩ·m Interval of auxiliary earth rods, setting range: 1.0 m ~ 30.0 m. AC true RMS voltage E.V Measurement range: 0~50V AC bandwidth: 40Hz ~ 200Hz Measurement basic accuracy: 2% Earth test other features Earth resistance measurement adopts square wave excitation test, the maximum open-circuit voltage is 50Vp-p, and the short-circuit current is <3mA. Automatic range detection in earth resistance measurement. RK resistance test, the line resistance effect can be removed. Earth comparison test, the measurement result can be evaluated by the preset "pass/fail (✓ / ✘)" limit and be given audio alarms accordingly.
