Test current: 3mA.
PI, DA
Features
- Test voltage provide 20V/48V choice;
- 2 pole resistance measurement;
- 3 pole&4 pole earth resistance measurement;
- 4 pole soil resistance measurement;
- Current Clamp selection method is used to measure earth resistance without breaking ground connection;
- Double clamp without auxiliary electrode is used to fast measure ground resistance;
- Auto and manual control the test frequency. 94Hz, 105Hz, 111Hz, 128Hz four frequency choices. Automatic frequency control(AFC) is automatically identified interference frequency and then selected the proper measurement, so that reduced the effect 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 store up to 100 measuring values, and uploading to PC by USB2.0 interface.
