Earth Grid Ground Resistance Tester
1.Excellent power frequency equivalence: The test current waveform is a sine wave, with the frequency deviation from the mains frequency ranging from a minimum of 0.1 Hz to a maximum of 10 Hz. This device can be used for measurements at both 50 Hz and 60 Hz frequencies.
2.Strong anti-interference capability. This instrument employs the measurement method combined with modern software and hardware filtering technologies, enabling it to exhibit exceptional anti-interference performance and deliver stable, reliable test data. 3. High measurement accuracy: the basic error is only 0.005 Ω, making it suitable for measuring ground grids with very low grounding impedance.
4.Powerful functionality: Measures current at grounding electrodes, voltage at grounding electrodes, grounding grid impedance, grounding resistance, grounding continuity, soil resistivity, and more.
5. Full-touch LCD display with an oversized graphical user interface – every step is clearly and intuitively presented. Operators can use the device without requiring any additional specialized training; simply tap the screen to complete the entire testing process.
6. The device is equipped with an internal calendar chip and high-capacity memory, allowing users to save results at any time. Historical data can be viewed or printed at any time. Both the current time and the stored time can be displayed and printed.
7. Advanced scientific data management: Instrument data can be exported via USB flash drive, and the data can be viewed and managed on any PC using dedicated software; the system also supports the generation of reports and test reports.
8. Safe and reliable: The instrument features grounding protection, current and voltage limiting protection, as well as audible and visual alarms to ensure the safety of both test personnel and equipment.
9. Features vector measurement functionality, enabling the measurement of ground grid impedance and ground grid pure resistance; also capable of determining the impedance angle.
