Operation Guidelines
Safety Precautions
- Always power off when connecting/disconnecting sensors due to high input impedance
- Use low-noise cables and minimize cable length to reduce interference
- Professional technicians should handle all connector welding and assembly
Performance Optimization
- Preheat unit for 15 minutes before measurement (30+ minutes if humidity exceeds 80%)
- Keep connectors clean and dry; use shield caps when not in use
- Avoid proximity to high-power equipment and power lines
Application Areas: Water conservancy, power generation, mining, transportation, construction, seismic monitoring, aerospace, and defense sectors.
