This instrument was designed by technical department of Huazheng Electric Manufacturing (Baoding) Co., Ltd.. Its performance is mainly reflected in:
u Breakthrough in self-test the boot a long time to wait, start immediately into the test.
u Breakthrough relay self-test mode, using advanced processing algorithms and digital integration technology, a fully intelligent.
u Break the old product to heavy issues, more in line with characteristics of handheld devices.
u New design, panel operation with 6 buttons, better performance.
u An increase of sound and light alarm, "beep—beep--beep --" alarm sound.
u Increase the interference signal recognition indicator.
u Improved anti-jamming capability and test stability.
u Stored data: 99 Units.
u Wider range: 0.01Ω-1200Ω
u Lower power consumption: Maximum operating current not exceeding 50mA.
HZRC series of Pincers Earth Tester is widely used in the grounding resistance measurement of the power, telecommunications, meteorology, oilfield, construction and the industrial and electrical equipment.
HZRC series of Pincers Earth 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.
HZRC series of Pincers Earth 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.
HZRC series of Pincers Earth Tester can measure the integrated value of the grounding body resistance and the grounding lead resistance.
HZRC series of Pincers Earth Tester is equipped with a long jaw, as indicated in the figure below. A long jaw is particularly suitable for the occasion of grounding with the flat steel.
In addition,
C+ Pincers Earth Tester is also able to measure the leakage current and the neutral current in the grounding system
