MS2308 Earth Resistance Tester

Features *2 pole resistance measurement. *3 pole & 4 pole earth resistance mearurement. *4 pole soil resistivity testing. *Current Clamp selection method is used to measuring earth resistance without breaking grounding connection. *Double clamp without auxiliary electrode is used to fast measuring grounding resistance. *Automatic frequency control (AFC) is automatically identified interference frequency and then selected the proper measurement frequency, so that reduced the affect of interference voltage. *Automatically measuring the interference voltage and the leakage current. The limited value will be alarmed. *Auto power off *Clock display *Double battery power supply and low battery indication. *Data storage function and uploading to PC by USB 2.0 interface.
