power on or the detector will not function correctly. If a problem is encountered turn the
detector off to reset the microprocessor.
When you first begin using the CS 8 SST
it is suggested that you set the Discriminate
control, Notch Select and Notch Width fully counter-clockwise. This turns the notch facility
off. To set the Notch Select, the Discriminate control must be at a lower setting than the
Notch Select control (set the Discriminate control to 9 o’ clock initially). As an example, set
the unit to reject iron and pull-tabs but still pick up nickel and coins of other materials: first,
turn the Discriminate control clockwise while moving the search head
over iron. A
screwdriver or your digging tool will work well. Increase the Discriminate control until the
unit no longer responds over iron. Next, set the Notch Width control to 12 o’clock- position.
Now, while moving the search head over a pull-tab, turn the Notch Select control clockwise
until the unit no longer responds. To check, move the search head over the coin and it should
respond. The LED should also indicate a good target, eg A to G on the lower scale.
Adjust the lower stem so that, with the unit in your hand and your arm extended towards the
ground, the search head is just off the surface. Using a slow sweeping motion, swing the
detector from side to side as you walk forward at a very slow pace. The slower you proceed
the more thoroughly you will cover the search area. Try to maintain the search head as close
to the ground as you can without actually touching
the ground. You should concentrate to
maintain this height off the ground, particularly at the end of the swing where the tendency is
to raise the search head before starting the swing back in the other direction.
The CS 8 SST will indicate a target with an audible identifying tone as well as lock on a LED.
Sometimes it helps to
read a target from more than one direction.
Turn 90 degrees over the
suspected target and sweep again. Sometimes the reading will change indicating that the first
reading may be false. Practice will make you more proficient at this technique. In most cases
good targets read the same from any direction and bad targets tend to change.
THE CONTROLS AND WHAT THEY DO
POWER ON/OFF SENSITIVITY
This control turns the instrument on and off, and controls the motion mode sensitivity. Fully
clockwise is the most sensitive position. These instruments have sophisticated programs that
recognise the sensitivity setting and set the instrument for optimum performance. If the
instrument gives a false reading, turn the control counter-clockwise as necessary to stabilise
the instrument. As you turn the control counter-clockwise the maximum detection distance is
reduced. This is similar to non-microprocessor controlled instruments, however, on this
instrument the unit is designed to also increasingly desensitise itself to mineralised ground as
you turn the control counter-clockwise.
DISCRIMINATION
This is a full range discrimination control.
When the control is fully counter-clockwise there
is zero discrimination. When fully clockwise the instrument rejects zinc and screw caps. Zero
discrimination allows the instrument to operate in the All Metal Motion Mode. There is no
discrimination at all and all targets, except the ground are picked up. To give you
an idea
