Product Overview
ETCR Series Clamp Earth Resistance Tester is widely applied in ground resistance measurement, loop resistance measurement in fields such as electric power, telecommunications, meteorology, oil field, architecture and industrial electrical equipment, etc. C+ tester can measure the leakage current of ground wire. ETCR Series Clamp Earth Resistance Tester measures the integrated value of ground resistance and resistance lead. When measuring ground system with loop, there is no need to disconnect the ground wire, without auxiliary electrode, which means safer and faster. ETCR Series Clamp Earth Resistance Tester can measure the ground fault which can not be measured by traditional method, can apply in the occasion where traditional methods are unworkable. The updated ETCR Series Clamp Earth Resistance Testers have better performance: Boot up instantly, avoid boot up errors; More reliable battery cover, convenient to change battery; Wider range, larger memory; Optional RS232 interface, available to transfer data to PC and generate report files, easy to analyze or backup data.
Key Features
• Break open a long time self-test waiting, boot immediately into the test.
• Breakthrough relay self-test mode, out of the relay, the use of advanced algorithms and digital Integrated processing technology, fully intelligent.
• Break the old product cumbersome problem, more in line with handheld instrument features.
• Increase the interference signal recognition, indicating the function, "beep - beep - beep -" tone, NOISE symbol flashing
• Improve the anti-jamming capability and test stability.
