Project Description
Support testing line anomaly detection, with 6 sets of testing modes, programmable testing and sorting can be achieved.
- HT9931A PV ground continuity tester is designed to grounding resistance characteristics of PV modules, it is also called grounding continuity tester.
- It is a stable and high accuracy instrument with 10~60A programmable current output and 0.01μΩ~600mΩ measurement range. Hopetech’s HT9931A has test line abnormal detection and built-in 3 groups test modes. Each mode is programmable and sorting.
- With optional RS485 interface, HT9931A can be easily implemented instrument network through MODBUS protocol
- HT9931A ground continuity tester is conforming to PV module standard IEC61730.
- Simultaneously display test current, grounding resistance, and test time
- Constant current linear amplification output
- The testing time can be set arbitrarily
- Sound and light alarm function
- Photovoltaic industry
- New energy vehicles
- Electronic components
- Medical equipment
