Product characteristics
Compared with the traditional hand-operated earth resistance meter, this instrument has the following characteristics:
1, the application of DC/AC conversion technology, set three-end button, four-end button as one, the use of power can be AC, DC dual use.
2, the use of phase-locked synchronous tracking detection mode, and switched capacitor filter, so that anti-interference ability is strong.
3, abandon the traditional manual hand-operated power generation mode, do not need human work.
4, no manual adjustment balance, clear panel touch key operation, LCD digital display makes the measurement is very convenient and rapid, eliminating the visual error of the pointer instrument.
5, the allowed auxiliary grounding resistance resistance value is very large, better ensure the measurement accuracy, high resolution.
6. In addition to testing the grounding resistance, it can also test the electrical group value of the low-voltage resistance conductor. Soil electrical composition and alternating voltage.
