Main functions and features
Lightweight and flexible. It integrates high-power transmission (1000Vx5A) and high-precision receiving functions into one, small size and light weight;
High-precision measurement-analog and digital multi-stage filtering to ensure 1V repeat accuracy, and high-quality original data can still be obtained in areas with complex geoelectric conditions;
Intelligent control-real-time display and storage of various data and drawing various curves; using universal SD memory card, USB2.0 high-speed transmission;
The panel is equipped with "infinity" pole, which can automatically measure PAS and PRS without manual switching;
Stable and reliable. The whole machine has a P67 waterproof level. The receiving end has instant overvoltage protection, and the transmitting end has overvoltage and overcurrent protection and high-voltage input reverse connection protection.
