10. Device adjustment and preparation for work
The metal detector is ready for use when the battery is charged and intact (the BAT LOW LED is not
lit up).
Before initial use, to the modifications with NiMH battery, please charge the battery at least 8
hours (from 8 to 16 hours) through the automatic battery charger available in the standard
package, as described in 12. The NiMH battery reaches full capacity and respectively
toughness, after at least about 5 cycles of charge-discharge.
After the metal detector is assembled according to the description in 8, it can be turned on via
turning the VOLUME potentiometer from left (level "OFF POWER") to right. This potentiometer
also serves for adjusting the desired audio volume (levels from "1" to "MAX").
The choice of manual or automatic mode to eliminate the influence of land is done by GROUND
switch described in 9.2, and the optimal way of tuning and balance, according to the selected
mode are made according to the description available in 9.3 and 9.4.
The setting of the desired degree of discrimination (distinction of the metals) is performed by
DISCR LEVEL potentiometer as description in 9.6. The width of the discrimination is set by
DISCR WIDTH potentiometer as description in 9.7, and the depth of discrimination is set by
DISCR DEPTH potentiometer as description in 9.8.
If the target is detection of any type of metals is necessary DISCR LEVEL potentiometer to be
set at level "0". For a complete exclusion of the discrimination, DISCR WIDTH potentiometer
and DISCR DEPTH potentiometer should be placed at its minimum level (DISCR WIDTH at a
level "NORM", DISCR DEPTH at level "0").
In the case of ignoring the whole black metal (detection of non-ferrous metals only), ie this is
a discrimination mode, it is necessary DISCR LEVEL, DISCR WIDTH and DISCR DEPTH to be
set at the following recommended levels:
1.
DISCR LEVEL potentiometer:
-
For LTC48X v2:
from „4“ to „6“.
-
For LTC48X v1:
from „6“ to „10“.
2.
DISCR WIDTH potentiometer:
-
For LTC48X v2:
„NORM“.
-
For LTC48X v1:
„NORM“.
3.
DISCR DEPTH potentiometer:
-
For LTC48X v2:
from „6“ to „10“.
-
For LTC48X v1:
from „6“ to „10“.
And lastly, with the THRESHOLD potentiometer are adjusts the audio threshold to the desired
level.
With this, the metal detector is adjusted and ready for work.
11. Search method
Metal detector BLISSTOOL LTC48X works in motion mode, ie it reacts to a metal object buried in
the ground only when the search coil is swung above it.
The searching for metal objects is actually by moving the search coil above the ground surface.
While doing this, the search coil has to be held parallel towards the ground surface and at a
minimum distance above it. The raising reduces the search depth.
