Our Digital Earth Resistance Tester Series
Features
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 94Hz,105Hz,111Hz,128Hz four 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 up to 100 measuring values, and uploading to PC by USB2.0 interface.
