EV-100 Deviation Change with R17

[Chuck - Raymarine - Moderator]

mswanicke,

The response from the engineering team is that both the deviation values are correct.

The initial value (as reported by the pop-up) is after the first minimal swing, as the solution is further refined via the continual calibration of EVO and results for larger deviation fields could change significantly over time.

Correspondingly, it is recommended that the EV Sensor Core's installation location be inspected again for sources of potential magnetic fields and any objects capable of producing a magnetic field be relocated. Alternatively, the EV Sensor Core should be tested in a different location. Should there be some concern that the EV Sensor Core is failing, then it should bench checked / serviced by Raymarine’s Product Repair Center.
