Remark:

It may have 10 digits or less unstable or wrong digits, it will not affect measurement
result.
Hold the Meter tight, do now release.  The Hall components are very sensitive not
only to the magnet but also to heat and machines reaction force.  Any shock will
cause the changing in reading in the short time.  Follow the below procedure to
