• The High-end Multifunction Clamp Earth Resistance Tester is applied in measurement of grounding resistance and the loop resistance (range: 0.010 Ω Ω ~ 1500); Leakage current measurement (Range: 0.000mA~40.0A).
• It has different kinds of display combination mode,can choose to display at same screen with resistance + current, resistance+time, current+time.
• Measurement range more larger,storage data 999 sets,power consumption more lower,adopt nickel-metal hydride rechargeable battery, supporting monitoring software with online real-time monitoring, historical query, software alarm setting, historical data reading, saving, reports and other functions.
• It can measure the ground fault and applied to the occasions that cannot be measured by traditional methods, and it is widely used for the earth resistance measurement of various equipment.
• When measuring the earth system with loop, there is no need to disconnect the grounding down lead, no need for auxiliary electrode, just need to clamp on the grounding lead directly. At this time, the displayed value of the meter is the comprehensive value of the grounding resistance and the grounding down lead resistance.
