Magnetoic field test in DO-160

[lfresea...@aol.com]

Hi all,
 
I'm looking into the best way to perform the magnetic field from equipment
test in DO-160. I'm currently using a compass, but has any one got a better
idea?
 
If I have to stick with a compass, has anyone go a preferred Vendor/model?
 
Thanks,
