Discrimination

When your CSI 250 is turned ON for the first time,
it will begin operating in the ALL-METAL mode.
This means that you will be searching using no
discrimination adjustments.
may never require any discrimination adjustments.
However, you can make adjustments by using
the ELIM and DISCRIM pushbuttons for specific
requirements.
The Lower Scale on the graphic display contains
12 segments. The illuminated segments represent
conductivities of the targets that will be detected
with an audible signal. Likewise, the absence of an
illuminated segment (i.e. notch) on this Lower Scale
will suppress an audible signal when a target with
this conductivity is detected.

Method 1 - Pass the searchcoil over an object to
be accepted or rejected as a target. Or, pass the
particular target across the face of the searchcoil
about two inches from its surface. If the segment is
displayed on the Lower Scale, that particular target
will be detected. If you want to reject that type of
target, press the ELIM pushbutton. The segment
on the Lower Scale will disappear, creating a "reject
notch". If the Lower Scale segment is not displayed,
press the ELIM pushbutton to illuminate it, creating
an "accept notch" and your CSI 250 will begin
signaling targets represented by that segment.
