1. The measured power frequency equivalence is good. The test current waveform is a sine wave, with a minimum frequency difference of 0.1Hz from the power frequency and a maximum of 10Hz. Can be used for measurement at two frequencies of 50Hz or 60Hz.
2. Strong anti-interference ability. This instrument adopts the cross frequency method for measurement, combined with modern software and hardware filtering technology, which makes the instrument have high anti-interference performance and stable and reliable test data.
3. High measurement accuracy. The basic error is only 0.005 Ω, which can be used to measure earth networks with very small grounding impedance.
4. Powerful functionality. Can measure current piles, voltage piles, ground grid impedance, ground resistance, ground conductivity, soil resistivity, step voltage, contact voltage, potential gradient, etc.
5. Full touch LCD display screen, super large full graphic operation interface, every process is very clear and clear. Operators can use it without additional professional training. The entire process can be tested by gentle touch.
6. Internally equipped with a calendar chip and large capacity memory, the results can be saved at any time. You can view historical records at any time and print them out. Both the current time and stored time can be displayed and printed.
7. Scientific and advanced data management: Instrument data can be exported through a USB drive and can be viewed and managed on any PC through dedicated software. Ability to generate reports and experimental reports
8. Safe and reliable. The instrument has functions such as grounding protection, current and voltage limiting protection, and sound and light alarm to ensure the safety of testing personnel and equipment.
9. Equipped with vector testing function, capable of measuring ground grid impedance and ground grid pure resistance. Can measure impedance angle.
10. Low wiring labor and no need for high current wires.
11. Integrated model, equipped with standard resistors and constant current source, facilitates on-site testing and reduces on-site wiring.
12. The instrument is easy to operate, and the measurement process is controlled by a microprocessor. As long as the correct measurement method is selected, data measurement can be automatically completed under the control of the microprocessor.
13. When users need high current testing (such as 30A), this instrument can be achieved by using an external power supply.
