After turning on the device, press a brief moment the
RESET
button and regulate the
FREQ.
regulator untill a slow ticking signal is hearable. This signal is acoustically
similar to a second hand. With each new setting press the
RESET
button to set the
zeroing. With the knob
AUDIO
set the desired volume.
There are 2 search methods to choose from:
MT
.
search method:
Thereto set the MODE control to the position
MT
. This search system, all metals.
With the ALLM. search method you draw more power from your device, but without
metal discrimination.
ID search method:
Thereto set the MODE control to the position ID. This search system uses the metal
discrimination. Once the ID -LED lights and a value will be shown in the display.
Ferrous metals will reach a value up to 120; Aluminium up to 40, about 70 copper
and gold reach a value about 160.
3.3 Precise localisation of metalobjects
Your GOLD SCAN works with the pulse induction searching system and is able to
detect, without setting the search coil in motion. With approximating the search coil to
a
metal object, the frequency of the clay/tone is increased. As soon as the search coil
is
exactly over the object, the highest clay/tone is reached.
With this method the exact place of discovery of the object can be located. By the
clay/tone duration the form of the object can be determined. For example, a long
lasting
high clay/tone stands in longitudinal direction for a narrow object, e.g. a pipe. A high
claytone in any direction indicates a circular object.
3.4 Hints to the search
Please note that you do not carry metal articles with you during the search process.
This could cause a wrong adjustment when pushing the
RESET
key and can
produce false indicator effects whilst the search process. In addition this can cause a
wrong discrimination or metal distinction.
During the search, make sure that the clay/tone remains constant, otherwise a wrong
adjustment by magnetic fields may occur. Especially with the search
with the 1 x 1 m coil (search framework) be certain that when an instable clay/tone
appears the
RESET
key is pressed. This must be accomplished in order to prevent
unwanted interferences by geomagnetism.
Strongly magnetized soils affect large search coils (searchframe) more than small
search coils. In the search with the large coil be certain therefore that the search coil
approx. 15-50 cm (depending upon need) is kept parallel to the soil and if possible
without jerky movements.
