Pin-Point; Discrimination; Assembling The Cs3Mx - C-SCOPE CS3MX Operating Instructions Manual

4) Pin-point. The 'motion' aspect of the CS3MX is switched off whilst the pin-point button is
depressed. In pin-point mode the search-head can be held still to determine the precise target
position. Pin-point mode operates in 'All Metal', ie whatever level of discrimination you have preset will
be switched off while the pin-point button is depressed. This is a useful facility which allows you to
trace around the edges of a signal to identify large pieces of iron. (Note: very large pieces of iron, such
as discarded agricultural machinery and iron stakes tend to give positive signals even when the
detector is set to high discrimination settings).
5) Discrimination. Set to '0' there is no discrimination, ie all metals are detected. Set within the green
area (1-4 on the scale) signals from most small iron rubbish are ignored, ie there is no audio signal.
The discrimination level can be increased (4-10, red area on the scale) so that the signals from more
categories of metal object are ignored.' (see 'Notes on Sensitivity, Ground Effect and Discrimination').

Assembling the CS3MX

The stem height adjuster should be slackened to allow the lower stem to enter the upper stem
section. The search-head lead may then be wound around the stem as shown in the photograph.
A search-head lead which is not well secured to the stem could move about causing false signals.
Cable ties or tape may be used to hold the lead in position. There are slots in the lower stem plastic
section into which the lead can be fi tted. When the search-head lead is fi tted correctly, the stem
adjusting device can be tightened at a height suitable for the user.
Adjust the position of the search-head so that it is parallel to the ground when the user is in a
normal standing position. Tighten the wing-nut on the search-head retaining screw. Do not over-
tighten. Friction of the head lugs against the neoprene washers keeps the search-head in position.
Excessive pressure on these parts should not be necessary.
(If some form of lubricant should ever fi nd its way onto these washers it will be necessary to disassemble
the parts, wash and dry them before careful reassembly).
