11. Introduction Introduction
ETCR series 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 to heavy issues, more in line with characteristics of hand-held devices.
New design, panel operation with 6 buttons, better performance.
ncrease 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-1200Ω
Stored data 99 Units. Lower power consumption, Maximum operating current less than 50mA.
ETCR series 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 grounding 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.
ETCR series Clamp Earth Resistance Tester have long jaw and round jaw style. Long jaw style is suitable for the occasion of flat steel grounding. C Type clamp grounding resistance tester can measure leakage current grounding system and the neutral current.
ETCR2000B + type Clamp Earth Resistance Tester has passed the certification of explosion-proof and met GB3836-2000 explosive gas environment with electrical equipment. he explosion-proof marks is Exia 2 BT3Ga. Explosion-proof qualified number: CE13.2263.It can be applied to the corresponding inflammable and explosive environment.
