VI. Application of the RESET-button
The function of the RESET-button is very important; the button should be
implemented after every modification.
After every turn-on procedure,
after every change of MODE-function,
after every swap of the searchcoil
during the search if sound gets unstable due to poor soil conditions or earth
magnetism.
While searching it must be observed that the sound is constant. If this not should be
the case, it is possible that a magnetic field caused a misadjustment.
It also must be ensured that during zero balance no metal objects are
located in the immediate vicinity of the metal detector. This can produce a
false calibration and unwanted indication effects.
VII. Indication of metal
The indication of a metal will be shown through the left-hand LED and the pulse tone.
Your device has a sound location system. With the approach of the searchcoil at a
metal object the tone frequency will rise. Once the soil is exactly over the object, the
highest tone is reached.
This method not only helps to locate the exact spot of discovery but it also detects –
based on the duration of the sound –the object‟s shape.
Examples:
A long-lasting high tone in longitudinal direction stands for a narrow object
(e.g. a tube),
a high tone in any direction calls for a circular object.
During search it often happens that side noises appear to be disruptive. Therefore we
recommend the use of the provided headphones.
