• The ETCR2100+ Clamp Ground Resistance Meter measures ground faults that cannot be measured with conventional methods, can be used in applications where traditional methods cannot be measured, and is widely used for measuring ground resistance of various devices.
• 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.
• Alarm Threshold Setting Range:Resistance: 1-199Ω; Alarm Sound and Light: "Beep-beep-beep" alarm tone, Alarm Symbol Flashing, Press AL key to turn on, turn off Alarm or set Alarm Threshold.
• Protection Level: Dual Insulation; Clamp Size: Φ32mm; Resistance Resolution:0.001Ω; LCD Screen: 4 Digits LCD display; Highest Resistance Accuracy:±1%±0.01Ω
• Structural Feature: Clamp CT; ETCR2100 + clamp ground resistance tester, ground resistance and loop resistance measurement (range: 0.010Ω ~ 1200Ω).
