RK2678X Earth Resistance Tester
RK2678X grounding 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/0~200mΩ; Measuring time/1~99s, synchronized display.
Measuring time can be set arbitrarily.
Alarming threshold 50-600mΩ
Alert value can be set continuously.
Qualified/Unqualified acousto-optic alert.
