C-SCOPE CS4ZX Operating Instructions Manual page 12

This control allows the user to optimise the detector for use on each site. This is
achieved by reducing the effect of natural mineralisation sometimes found in the ground,
but it must be individually set for each ground type.
In high performance detectors, like your CS4ZX, mastering this control is essential to
gain the full capabilities.
The range provided should allow accurate setting to exclude from the most neutral
ground through to more 'mineralised' ground. This control is used in conjunction with the
INLAND/BEACH switch described in B.i. above.
iii. METER FUNCTION SWITCH (P in diagram 7).
This is a three position switch located on the front panel in the central position and is
labelled METER DISC/GROUND/BATTERY. It allows the user to select which
information the meter will display.

a) Meter Disc
a. METER DISC
In this position the meter responds to signals by referring to the pre-programmed
discriminating channel of the detector. After retuning the needle will normally be in
the centre of the scale. The needle will move to the left for iron and small pieces of
aluminium foil, i.e. a negative response, and stay central or move to the right for
other targets, i.e. a positive response.
b. GROUND
With the switch in this position the meter shows the responses from the variable
ground excluding channel of the detector. The meter will show no response to
ground mineralisation when the BEACH/INLAND switch and the GROUND
rotary control have been correctly set. When correctly set, all targets will produce
a positive response on the meter, i.e. the needle will always move to the right.
Note: in the BEACH setting, items of iron can give a negative response at high
settings of the GROUND control.
This facility is provided for setting the GROUND control. The control should be
adjusted until the proximity of the ground causes no movement of the needle. The
detector should be retuned before the head is presented to the ground after each
