The frequency selection table can only be used with the grounding resistance meter of the large ground network to measure the surface potential gradient, step voltage, and potential difference with anti-interference.
Strong anti-interference capability. It uses high-precision adaptive digital notch technology, which can automatically track and suppress interference frequencies. The theoretical suppression of this algorithm is close to one in a million. Compared to some imported selective frequency voltmeters with suppression capabilities of several percent, the selective frequency voltm can virtually ignore the presence of interference.
Powerful features. It can measure step voltage, contact voltage, transfer potential, potential gradient, transfer potential, etc.
Full touch LCD display, extra-large graphic operation interface, every process is very clear. Operators do not need additional professional training to use it, just light touch can complete the entire process of testing.
It is internally equipped with a calendar chip and a large-capacity memory, which can save results at any time. Historical records can be viewed and at any time. Both the current time and the storage time can be displayed and printed.
Scientific advanced data management: Instrument data can be exported via USB drive, and can be viewed and managed on any PC with dedicated software, capable generating reports and test reports.
The instrument is easy to operate, and the measurement process is controlled by a microprocessor. As long as the correct measurement mode is selected, the measurement can be automatically completed under the control of the microprocessor.
