ETCR 2000+ Earth Resistance Tester, in the measurement of a grounding system with loop current, does not require breaking down the grounding wire, and need no auxiliary electrode. It is safe, fast and simple in use. ETCR 2000+ Earth Resistance Tester can measure out the faults beyond the reach of the traditional methods, and can be applied in the occasions not in the range of the traditional methods. ETCR 2000+ Earth Resistance Tester can measure the integrated value of the grounding body resistance and the grounding lead resistance. --------------------------------------------------------------------------------------------------------- .Technical specifications Earth Resistance Tester (ETCR2000C+) Technical specifications Range 0.01-1200Ω; 0.0mA-20A Resolution 0.001Ω; 0.05mA Sound and light alarm "beep - beep - beep -" alarm sound, Flashing alarm symbol, By AL key to open, close, set LCD 4-digital LCD, 47*28.5mm in length Working temperature -20-55 degrees Relative Humidity 10%-90% Explosion-proof mark Exira ∏ BT3 Shift Automatic Shifting External Magnetic Field <40A/m External Electric Field <1V/m Single Measurement Time 0.5 second Resistance Measurement Frequency >1KHz The Measured Current Frequency 50/60Hz Automatism Storable Measurement Data 99groups Setting Range of Resistance Alarm Critical Value 1-199 Ω Setting Range of Current Alarm Critical Value 1-499mA Protection Level Double insulation Structural Feature In the jaw way CT Power Source 6VDC (4*5# alkaline battery) Span of Jaw 28mm Net Weight (including batteries) 1160g Dimension 285mm long, 85mm wide,56mm thick Accessories Meter: 1 PCS; Test Ring: 1 PCS; Meter Box:1 PCS
