5. الصيانة
Proper maintenance ensures the longevity and accuracy of your CHCNAV I93 GNSS RTK Receiver:
- تنظيف: Regularly clean the exterior of the receiver and controller with a soft, damp القماش. تجنب استخدام المنظفات أو المذيبات الكاشطة.
- تخزين: Store the equipment in its protective carrying case when not in use. Keep it in a dry, temperature-controlled environment.
- العناية بالبطارية: For optimal battery life, avoid fully discharging the battery frequently. Charge the battery regularly, even during periods of non-use.
- تحديثات البرامج الثابتة: Periodically check for and install firmware updates for both the receiver and the controller to ensure you have the latest features and performance enhancements.
- فحص الكابلات: Inspect all cables for signs of wear or damage before and after each use. Replace damaged cables immediately.
6. استكشاف الأخطاء وإصلاحها
فيما يلي بعض المشكلات الشائعة وحلولها:
- لا توجد إشارة GNSS: تأكد من أن لدى المتلقي رؤية واضحة view of the sky. Check antenna connections. Verify that the correct satellite constellations are enabled in the software.
- تحديد الموقع بشكل غير دقيق: Check the RTK correction source (base station or network RTK). Ensure the survey pole is plumb and the IMU is calibrated if using tilt compensation. Verify the coordinate system settings in LandStar 8.
- وحدة التحكم لا تستجيب: Restart the LandStar 8 application or the controller itself. Ensure the battery is charged.
- 'Test Equipment' Designation: Some units may be labeled as 'test equipment' for internal purposes or specific market regulations. This typically does not affect the functionality or accuracy of the device for its intended use.
- التوافق الإقليمي: The CHCNAV I93 is designed for global use, supporting multiple GNSS constellations. However, specific network RTK services or local regulations might vary by country. Consult local surveying authorities or your dealer for region-specific information.
