Overview ETCR2100C+ Clamp Earth Resistance Tester is our company's technology research and development team on technical quality of the pursuit of excellence, through continuous innovation to improve, upgrade with the old product. Its performance is mainly reflected in: Breakthrough in self-test the boot a long time to waiting, start immediately into the test.Breakthrough relay self-test mode, using the most advanced processing algorithms and digital integration technology.Breakthrough the old product too heavy issues, more in line with characteristics of hand-held devices.New design, panel operation with 6 buttons, better performance.Increase sound and light alarm function, with "beep-beep-beep” alarm sound.Increase the interference signal recognition indicator function, with "beep-beep-beep” indicator.Measurement range: 0.01Ω-1200ΩStored data 99 Units. Lower power consumption, Maximum operating current less than 50mA. ETCR2100C+ Clamp Earth Resistance Tester is widely used in the grounding resistance measurement of the power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment. In the measurement of a grounding system with loop, does not require breaking down the grounding down lead, and no need the auxiliary electrode. It is safe, fast and simple in use. The tester can measure ground faults which cannot be measured by traditional methods. It can be used in applications where traditional methods cannot be measured, because the ETCR series clamp grounding resistance meter measures the combined value of grounding body resistance and grounding lead resistance. Field Application The application of machine room earth resistance measurement The machine room of telecommunication system normally in the upper deck of the building. It is hard to use the meg-ohm meter to measure. However, ETCR Clamp meters are very convenient to test. The application of substation earth resistance measurement ETCR series clamp meter can use to test the situation of contact and connect of circuit. With the help of one test line, it can be used to test the connect situation of equipment in station and the grounding system. The application of building lightning protection grounding system measurement If the earth poles of the building are independent of each other, the earth resistance can be measured by clamp to testing any of the earth poles, and the earth resistance can also be measured by clamp the building roof lightning arrester.When the measured value is less than the allowable value, the earth electrode is qualified.If the measurement value of the clamp meter is larger than the allowable value, please use ingle earth point method to measurement. From the measuring principle, ETCR series Meter can only measure the loop resistance, the single-point grounding is not measured. However, users are able to use a testing line very near to the earth electrode of the grounding system to artificially create a loop for testing. For details, please read user manuals.
