Earth Resistance Meter Detector Current Tester 1200ohm 40A RS232 Alarm Function

Description

Earth Resistance Meter Detector Current Tester 1200ohm 40A  RS232 Alarm Function
Introduction:
multi-functional clamp ground resistance tester, grounding resistance and loop resistance measurement (range: 0.010Ω ~ 1200Ω); leakage current measurement (range: 0.00mA ~ 40.0A). When measuring the looped grounding system, it is not necessary to disconnect the ground deflector and no auxiliary electrode is needed. Just clamp the meter and clamp it directly on the ground lead. The value displayed by the clamp meter is the grounding body resistance and The integrated value of the ground lead resistance, this measurement method can quickly and safely obtain the measurement results.
