Product Installation
- Installation method: Use M7 screws to fix and install on the side.
- The main purpose of this product is to monitor the grounding resistance value, which requires two auxiliary grounding grids to accurately calculate the resistance value of the tested grounding grid.
- This product is powered by an external DC 5V, while GPRS is powered by solar energy and batteries.
- Ground wires should avoid areas with strong magnetic fields, and it is best to use metal and steel pipes for wiring.
- Connect the power and communication wires according to their colors, and do not connect them incorrectly.
