1. Double frequency conversion,strong anti-interference ability. The instrument adopts the method of different frequency measurement, and with modern software and hardware filtering technology, the instrument has high anti-interference performance, and the test data is stable and reliable.
2. The precision of measurement is high. The basic error is only 0.005 Ω, which can be used to measure the earth network with very small earth impedance.
3. Powerful function. It can measure current stake, voltage stake, grounding grid impedance, grounding resistance, grounding conduction, soil resistivity, step voltage, touch voltage, potential gradient and so on.
4. GPS included Angle function.
5. Vector shunt function.The instrument automatically subtracts the current that is transferred by the tower to calculate more accurate test results.
6. Built-in 1500 Ω imitate human body resistance, when testing step voltage ,users can get the real step voltage data and curve.
7. The operation is simple. All Chinese menu operation directly shows the measurement results.
8. Simple wiring ,no large current line is needed.
9. Built-in thermal printer, easy to print and save test results.
10.USB for easy copying test data.
11.Powerful PC software
12. It is safe and reliable. The instrument has the functions of earthing protection, current limiting and voltage limiting protection, sound and light alarm, and so on to ensure the safety of the test personnel and equipment.
