p70 Heading of 180 degrees

mswanicke,

The reported maximum deviation value is quite high, indicating that the EV-1 Sensor Core is experiencing a significant magnetic field in its present location. The EV-1 Sensor Core should be located at least three feet from anything constructed of ferrous materials (ex. engine block, refrigerator, tools, etc.), anything constructed of magnetic materials (ex. electric motors, speakers, etc.) other electronics, and high current carrying cables. After locating a more suitable location for the EV-1 Sensor Core permitting it to sense a much lower maximum deviation, the vessel should once again be taken for a short boat ride. Should newly reported maximum deviation now be less than 15 degrees the heading still be in error, then the heading error may adjusted by either rotating the EV-1 Sensor Core within its mount or using the Compass Offset feature (see section 5 (page 4) of the Evolution Autopilot Set-up and Commissioning with p70/p70R guide) supported by the p70/p70R Autopilot Control Head. Up to 9.9 degrees of EV-1 Sensor misalignment may offset via the p90/p90R's Heading Offset feature.
