6: SMF (STATIC MAGNETIC FIELDS)
Setting range is 1-100
Factory preset 50
Description
SMF is the interaction of your coil's movement through the Earth's
Magnetic Field.
As a search coil is swung through the Earth’s magnetic field (Static
Magnetic Field), an undesirable signal (voltage) is generated in the
search coil particularly when detecting vertically up the sides of banks
or cuttings.
The SMF value is used to adjust/cancel this Static Magnetic Field.
The bigger the coil and the faster the swing speed the bigger the
problem.
The factory pre-set setting of 50 is used to minimize this signal.
Further, if as a result of the ageing of the electronic components the
SMF cancellation can be adjusted.
To adjust SMF, use a large coil, and:
•
swing the coil vertically as when detecting vertical creek banks.
•
Adjust SMF up or down to minimize any signal fluctuation.
Adjusting SMF
Select Menu Option #6, then press the
button to open the SMF
setting, then either:
•
Increase the SMF setting with the
button.
•
Decrease the SMF setting use the
button.
