the symbol „_“. If there is a difference in both levels balance of the device should be
performed through
„POWER / CLEAR“.
In the discrimination modes, with the pressing of
„SELECT“
,
the
following
settings can be selected:
„
Low tone“ -
(1, 2) – 1 is low tone turned off, and 2 is low tone turned on.
„
olD1“ -
setting of the position of zero for the indication of
ID1 –
it can be moved to the
left or to the right along the scale. I. e., if an object has an indication for
ID1 – „+2“,
if
„
olD1“
is decreased with 4 units, the indication for the same object will become „
-2“.
In
this way, some undesired alloys, stained iron items or caps and other objects of foil can be
avoided and the device to register them with negative values , by preserving the positive
indications for the „more ferrous“ objects – coins, rings etc.
„
olD2“ -
analogue to „
olD1“,
but for the indication of
ID2.
Discr
(1, 2, 3, 4) – choice of a sub – mode of
AUTO DISCR. / auto discr.
rng1
(1, 2, 3) – choice of allowable range for the value of
ID1
upon memorization of a
definite object.
rng2
(1 – 10) – choice of allowable range for the value of
ID2
upon memorization of a
definite object.
The „
AUTO DISCR“
mode is suitable when the background of the soil is negligibly
small and doesn't change in considerable degree the signal received upon localization of a
metal object. I. e., in it one can work on low mineralized or sandy soils.
At a higher mineralization of soil, it gives a signal which can increase considerably,
especially at approaching of the coil to cling to ground surface. Highly mineralized soils,
especially when containing a considerable amount of moisture, additionally increase the
common signal and it can have great values. If in such type of soil there is nonferrous
metal, it will change the common signal to more positive values, but to overcome the
background of the soil, the signal to the object will have to be considerably stronger, i. e.,
the sensitivity because of the background will decrease. For such cases suitable are the
„
auto discr“ / “AUTO DISCR“
modes.
The next mode of discrimination is „
auto discr“ / “AUTO DISCR“
with a sub –
mode
„accept / ACCEPT“
. In this sub – mode the device will not produce any sound
signal until it memorizes a definite nonferrous metal, and the indication on the 3
rd
row to
the right of the display is:
“accept...
or
ACCEPT...“.
