[CA11] EV-1 Calibration

[CA11] EV-1 Calibration
Is it possible to validate the EV-1 Compass calibration using an Axiom panel? I do not have the full autopilot solution, I just purchased the EV-1 to feed heading data, while stopped, to the chart.

I've tried forcing the automatic calibration but running figure 9's at 5-10 MPH and I've even seen pop up messages on the Axiom indicating the deviation was configured. Yet the results seem inconsistent.

The compass appears to correct it's deviation during long runs but then when powering up the system the next time it can be off by 20+ degrees.

Thoughts?

Thanks in advance.

Welcome to the Raymarine Forum pinkish_panther,

Many will utilize an EV-1 CCU for just such purposes, particularly if there is any chance of installing the remaining components of an Evolution autopilot in the future. For those having MFD's running LightHouse 3 software who are not seeking to install an autopilot, the AR200 Augmented Reality sensor can be a more cost effective means of supplying heading data to the system. The AR200 will also support LightHouse 3's Augmented Reality feature.

Regarding the symptom reported, please indicate the maximum deviation detected by the EV-1 CCU (HOME->SETTINGS->AUTOPILOT->MAX DEVIATION). Please additionally include some photos of the EV-1 CCU's installation location showing all within 3' of the EV-1 CCU. Please additionally note what is located on the opposite side of the bulkhead that the EV-1 CCU has been mounted to.

Thank you, that put me in the correct direction.
I went over to the boat this evening and followed your suggestion, I had never gone into the Autopilot section before. When I enabled it the compass calibration options are there - I’ll not be able to try it until it goes into the water but I expect that will do it with the calibration lock set to on once it seems accurate!
