ADJUSTING THE
DETECTION DISTANCE
The scale setting on the PCB’s left
and right edge, along with the lens you
select, determines the detection dis-
tance.
Note:
The detecting distance is mea-
sured at an operating temperature of
68°F (20°C).
Follow these steps to adjust the detec-
tion distance.
1. Use the tables to determine the
scale setting for the desired
detecting distance for the lens you
installed.
2. Insert the PCB between the two
PCB holders on each side of the
back case, and route the cable
through the lower slot on the PCB.
Align the desired scale setting (1–
5) with the top of the PCB holder
on the left side of the case and the
bottom of the holder on the right
side of the case.
3. Secure the PCB with its screw.
Note:
Before replacing the upper
case, be sure the jumper is on
both pins of P1. If the jumper is off
one pin of P1, the test indicator
will not light.
