REFLECTOR: Compass Calibration

[Al Gietzen]

Ron;

 

One solution is to replace it with an electronic compass with remote mounted
magnetometer.  I’m going to try the Stratomaster MAG-1.

They have 2 ¼” and 3 ½” versions

Subject: REFLECTOR: Compass Calibration

 

I have a vertical card compass mounted in my instrument panel that has an
error that I have not been able to calibrate out:

 

At North, It indicates 15 degrees

At South, it indicates 165 degrees

At east and west it is dead on.

 

If I adjust the error out at north - make it read 0, then it reads 150 when
pointed south or vise versa - if I calibrate the error out at south - make
it read 180, then it reads 30 degrees when pointed north.

 

I understand that a small magnet(s) can be mounted near the compass to help
take these errors out.  I have tried this I am not having much luck in
removing these errors.  

 

Any one have any experience in correcting these errors?

 

THANKS

Ronnie
