The
aim
of thissection
is to describe
how
to setupthedetector
for a particular
product,
including
automatic
setting
of detection
parameters
andcalibration
of timersfor
accurate
rejection.

4.1 Detector
Display
and Keypad
Switch

Figure: Detector displayandkeypad
Thedisplay
has
two
linesof20characters,
and
after
power
onorreset,
thetopline
shows
the current
product
name
andthe bottom lineshows
a "bargraph". The
bargraph
can
beusedtosee
how
good
a product setupis:
thecircles
showthesize
ofsignal

themorecircles
the
larger
thesignal.Solid
circlesindicate
that metalhas beendetected.Hollow
circles
indicate
product

or metal
contamination
that
isnot large
enoughtotriggerthemetaldetector.
lf manyhollow
circles
are
displayed
eachtimea productpasses
thenthedetector
maybeat risk
from
false
triggering.
When
no

4.2 Initial
Test
Everydetector
is shipped
witha testsample
- a small
piece
of metal
to testthe
detector
with.

beembedded
intheend
of a 30cm
grey
plastic
stick,
orina credit-card-sized,
plastic-laminated
card.
Before
thedetectoris
shipped,
it is setupto see thissamplewithout
false
triggering
(false
triggering
is
whenthe
detectorindicates
that
ithas
seenmetal
when
none
ispresent,
andis
due
to electrical
noise,
vibration,
large
product
effect,etc.).
This
setupis stored
onthe

under
thename
"FACTORY
