MS2307,MS2306 Intelligent Grounding Resistance MeterDetailed product description：

Detailed information

1) Six measurement methods, including bipolar AC, bipolar DC, three pole, four pole, current clamp selection method, and dual clamp head without auxiliary pole method, are used to measure the grounding resistance, meeting the needs of various measurement environments.  
2) The measurement voltage is optional at 48V/20V, and the measurement frequency is available in four options: 94Hz, 105Hz, 111Hz, and 128Hz. It also has an automatic frequency selection function, which automatically selects the frequency with the least interference for measurement.
3) The 4-pole method can be used to directly measure soil resistivity;
4) Capable of automatically measuring interference voltage and leakage current;
5) It has a measurement data storage function, which can store 100 sets of measurement data and upload them to a PC for display analysis and output test reports.
6) Dual power supply, optional dry battery and rechargeable battery power supply technical specifications:
