DISCRIMINATION MODE OF SEARCH
Discrimination- The ability of the detector to react to certain types of objects while
ignoring others. In certain cases this is useful to improve the comfort of the search.
Turning on or off discriminate is performed by pressing the button [
AM/DISC
]. When
discrimination mode is enabled [
D]
, briefly pressing the [
AM/DISC
] button the
discrimination
MAP
will appear. This view will give the user a quick view of what
discrimination levels have been set. The discrimination card is broken into 18 sectors with
10 VDI numbers per sector. The exception is VDI n80 to +90 which obviously has
11 numbers in this sector. Each sector will appear as either a completely filled box, partially
filled box or completely empty box. A completely filled box indicates this VDI sector has
been completely included and will not be discriminated out. A partially filled box indicates
some VDI numbers have been excluded and those specific VDI numbers will be
discriminated. While a completely empty box indicates all VDI numbers in this sector have
been discriminated out.
The specific type of discrimination response is set by setting the mode
Visual
Discrimination
(p.
23)
. On the left side of the screen is the current mode of
discrimination. If the mode visual discrimination is enabled the letter
V
will be displayed
When a target is detected and it is not included in the discrimination map the target will
not generate an audio response nor will a hodograph or VDI value be displayed.
If Visual discrimination is off (discriminate mode is enable) the letter
D
will be
present. In this case a target that is not included in the map will not make an audio
response however there will be a hodograph and VDI of the rejected target.
When discrimination is turned off (
All metal
mode ) the Letter
A
will appear and
all targets will generate an audio, hodograph and VDI response.
