Advanced Earth Resistance Tester MS2308

Jul 21, 2011

♦Test voltage have 20V/48V Provide choice.
♦2 pole resistance measurement.
♦3 pole & 4 pole earth resistance measurement.
♦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.
♦Auto and manual control the test frequency. Have 94 Hz,105Hz,111Hz,128Hz for frequency provide choice.
♦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: Can memorize u p to 100 measuring values, and uploading to PC by USB2.0 interface.
