How do I Measure the Polarity of a Permanent Magnet

bar magnet with polarity South top (green) and North bottom (red)

Transvers probe:
determination of polarity of a permanent magnet with transverse probe (south pole)
 
Axial probe:
determination of polarity of a permanent magnet with axial probe (south pole)

With FM 302 and all uniaxial AS-probes it gives:
display > 0 : South,          display < 0 : north.
