C. FUNCTION CONTROL
This switch allows
the
user
to
choose a mode setting most suited
to
a particular site. The 1200-8
has
two
main modes
of
operation.
1. Meter
Discrimination
Mode:
In this mode the
1200-8
offers ground exclusion
via
the
audio channel
whilst
simultaneously discriminating via the meter channel. The objects
rejected in this mode are small pieces
of
iron
and silver paper.
2.
Analytical
Modes: Tt;lis main mode
is
divided
into
three optional modes:
G -
01
G -
02
G -
03
In
these, modes
the
detector
can
be
used
in either a ground exclude mode (G)
or
a
discriminate mode (D)
01,02
and
03
which
offer
increasing levels
of
discrimination.
Recommended Mode Settings
In general the Meter Discriminate mode is
the
recommended mode
~,o,tting
for
most
sites.
It
is
an
extremely effective mode
of
operation, because
it
is
simple.
The
correct
level
of
ground exclude
is
electronically pre-set
as
is
the
discriminate level.
The
level
chosen
for
ground exclude
is
designed
for
a heavily mineralised inland site.
The
level
chosen
for
discriminate
is
the setting where
the
highest level
of
discriminate can be
achieved
without
sacrificing performance. There
is
therefore no danger
of
rejecting
anything
worthwhile,

F.
& L. ADC AUTOMATIC DISCRIMINATE
CONTROL
In practice, when
you
have chosen and set
your
operational mode.
the
ADC
control
is
the
only
control
necessary
to
operate
the
1200-8.
The
ADC
control
has
two
main
functions:
1. The
AbC
acts
as
a
memory
recall
control
to
automatically
recall
the
'optimum
level
of
tuning.
2. The
ADC
acts
as
a
function
selector.
For
example.
if
the
function
control
has been set
at G-D1.
to
select
the
G mode
the
user
will
press
the
switch
to
the
'Ieft
and then release
it.
To
select
the
D mode. press
the
ADC
switch
to
the
right and
then
release
it.
In
the
meter discriminate mode
the
ADC
control
only
acts
as
a
memory
tuning
recall
switch.
The switch
(Ll
is
an
optional
ADC
control
for
use
when
the
detector
is
used
with
the
optional
hipmount
armsaver
kit.
G. METER
1.
The meter acts
as
a
battery
check.
See
(HI.
,
2. The meter
will
give a visual
indication
of
the
optimum
tuning
level when
the
needle
is
in
the
central
TUNE
position.
3.
When
discriminating in a 0 mode
or
when in the Meter Discriminate mode. the
meter
will
show a negative response
to
unwanted items (needle
will
swing
from
the
centraJ setting
to
the Jeft).
4. When
pinpointing
a target signal,
the
fullest
deflection
of
the
meter
to
the
right
will
indicate
that
the
object
is
situated under
the
centre
of
the search head.
