Massedurchgangsprüfer

CS2678X Digital Earth Resistance Tester is used to measure the ground resistance of the inner electrical equipment; it presents the resistance between the exposed conductive part and electrical equipment. The tester applied 4 points testing method in order to eliminate the influence of the grounding resistance. That is to add current between the exposed conductive part and the all grounding point, then measuring the voltage of both points, finally calculate the resistance. Performance Features:Measuring current:AC/5 30A; Measuring Resistance/0 600mΩ; Measuring time/1 99s,digital display.Measuring time can be set arbitrarily.Alarming threshold 50-600mΩAlert value can be set continuously.Qualified/Unqualified acousto-optic alert.Technique Parameter:Model Test current(A) Ground resistance (mΩ) Resistance accuracyAlarm range(mΩ)Test time CS2678X (5-30) (0-600) ±(5%+3counts) (50-600) (1-99) Dimension width×height×length=315mm×165mm×250mmWeight (about) 11kg
