Discrimination (Accept/Reject) Scale
When a target is detected, an ID number
appears on the left hand side of the
screen and a bar and cursor appear in the
Discrimination scale along the bottom of the
screen in the Graphic Identification Bar. In
Coin and Coin & Jewellery Modes a Target
Icon also appears on the right hand side of
the screen.
The location of the target cursor corresponds
to the discrimination rating or ID number of
the object.
When an object is detected, the target cursor
will momentarily flash.
On the Graphic Identification Bar the black
area represents rejected target IDs and the
clear area represents accepted target IDs.
Interpreting target responses
To Modify the Discrimination Pattern:
The Discrimination Pattern of a factory
preset mode can be modified and saved as a
personal setting, so that your own preferred
Discrimination Pattern is ready for use any
time you wish.
The icon will be displayed on the screen
to indicate that a mode has been temporarily
modified.
There are three methods of modifying the
Discrimination Pattern.

object’s ID.
3 Wave the coil over the target and check
that it is being rejected. If it still produces
a response, reject its new ID by pressing
Accept/Reject a second time.
