Brand New ETCR3000 Digital Earth Resistance Tester 0.01Ω~2000Ω 0~600V Introduction: ETCR3000 Digital Earth Resistance Tester is specially designed and ... moremanufactured for field measurement. Adopting the latest digital and micro-processing technology, 3-pole or 2-pole method for earth resistance measurement, with a unique function of wire resistance verification, anti-interference capability and the ability to adapt to the environment, to ensure high precision, high stability and reliability for prolonged measure, which is widely used in electric power, telecommunications, meteorology, oil field, construction, lightning protection, industrial electrical equipment and other earth ground resistance measurement. ETCR3000 Digital Earth Resistance Tester has a unique function of wire resistance verification, more accurate on measuring on-site low value earth ground resistance. Which can avoid error caused by resistance change due to prolonged usage of testing wire; avoid error caused by testing wire that is failed to be fully inserted into tester interface or by poor contact; avoid error caused by users’ replacing or lengthening testing wires. ETCR3000 Digital Earth Resistance Tester is composed of host machine. Monitoring software, testing wires, communication wires and others. The large LCD display of host machine is with blue backlight and bar graph indicating that can be seen clearly. At the same time it can store 400 sets of data, fulfilling historical inquiry and online real-time monitoring through monitoring software, dynamic display, with the maximum, minimum, and mean indicators, with alarm settings and alarm indicator, and with the functions like historical data access, reading, preservation, report forms, printing and so on. 2. Technical Specifications Model ETCR3000 Function Earth resistance measurement. Earth voltage measurement, Low resistance measurement Power Supply DC 9V(Zi-Mn dry battery R14S 1.5V 6 PCS. Continuous standby for 300 hours) Measuring Mode Precise 3-pole measurement. Simple 2-pole measu
