Discrimination (Accept/Reject) Scale
When a target is detected, an ID number appears on the left hand
side of the screen, an icon appears on the right hand side
of the screen, and a bar and cursor appearing in the
Discrimination scale along the bottom of the screen in
the Grahic Identification Bar.
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 shaded area represents rejected target IDs and the clear
area represents accepted target IDs.

Interpreting target responses
The Target ID Range have 51 numbers from (–10 to +40).

To modify the Discrimination Pattern
The discrimination pattern of a factory pre-set 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.
Method 1 – To reject a specific target/object:
a. Wave the coil over the object. The detector will move the cursor to indicate the object’s
position on the scale, and the targets ID number will appear on the screen.
b. Press the ACCEPT/REJECT button to reject the object’s ID.
c. 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.
Method 2 - To reject a specific Target ID number:
a. In the Detect screen use + and – buttons to select the ID you want to modify. The cursor and
the Target ID numbers will indicate the selected ID.
b. Press the ACCEPT/REJECT button to either accept or reject that ID. You will notice the band
on the discrimination scale will become shaded if rejected or clear if accepted. The
ACCEPT/REJECT button will toggle between accepting and rejecting targets.
