APPLICATIONS PRECAUTIONS
Several precautions should be observed when using mag-
netometers in general:
the earth’s magnetic field are quite dramatic between
North America, South America and the Equator region.
?
The presence of ferrous materials—such as nickel, iron,
steel, cobalt—near the magnetometer will create dis-
turbances in the earth’s magnetic field that will distort x,
y and z field measurements.
?
Perming effects on the HMR board need to be taken
into account. If the HMR board is exposed to fields
greater than 10 Gauss (or 10 Oersted), then the board
must be degaussed. The result of perming is a high zero
field output code that may exceed specification limits.
?
?
The presence of the earth’s magnetic field must be taken
into account when measuring other x, y and z, fields.
The variance of the earth’s magnetic field must be ac-
Degaussing devices are readily available from local elec-
tronics outlets and are inexpensive. If the HMR board is
not degaussed, zero field offset values may result.
