If the 171h is a pressure transmitter or actuator with a 4-20mA loop:
Because "fix" is broad, you need to match the part to the symptom. The most common replacement parts for the Covadis 171H are: covadis 171h fix
Fixing a Covadis 171H is not for the faint of heart. It requires patience and a clean workspace. Here is the roadmap for the most common "Major Fix"—the Spindle/Drawbar rebuild. If the 171h is a pressure transmitter or
| Cause | Description | |-------|-------------| | | Base antenna sees obstructions (trees, buildings). | | Short observation time | Base not initialized long enough. | | Multipath | Reflections from nearby metal, water, or glass. | | Incorrect antenna height entry | Height in Covadis config mismatched with physical setup (leads to false residuals). | | Base/Rover mismatch | Different GNSS constellations enabled (e.g., base uses GPS+GLONASS, rover GPS only). | | Radio link interference | UHF or internal radio weak → corrections delayed. | | Firmware bug | Specific to Covadis 171H revision. | Here is the roadmap for the most common
To apply this fix effectively, users should follow these steps: Verify Version : Ensure your base installation is at least version 17.0. Administrative Rights
