In many applications, this is all
that is needed. In cases where the
target is marginal, the user may
need to manually adjust the
sensitivity after trying the Auto
mode.
6.2 Manual Mode
Aim the laser at your target. Turn
the Sensitivity Adjust knob (7)
between Min and Max until the
On Target LED (1) starts blinking
or comes on solid. If you can’t get a good setting, change the gain.
Press and release the Learn/Gain button (6) to change the gain of the
input amplifier. Each time the button is pressed, the gain is changed.
The Auto/Gain LED (3) will blink to show what gain has been selected.
If the button is held down, the gain will increase automatically after
each LED ‘blink’ pattern. Refer to Table 2. The larger the gain, the
weaker the signal being picked-up. Using a large gain for a strong signal
is not recommended since the input will saturate.
7.0 ADVANCED FEATURE (TARGET POLARITY)
The input circuitry can be set to optimally work with two different target
types: a reflective (white, shiny) target on a mostly non-reflective (black,
dull) background or a non-reflective (black, dull) target or a mostly reflective
(white, shiny) background. These will be referred to as a white target or a
black target. When the unit is first turned on, the On Target LED (1) will
indicate which target type the sensor is set up for. While the Laser On
LED (2) is blinking, the On Target LED will be on for a white target or off
for a black target. The unit will still work when set up for the “wrong”
target type, but it won’t have as great a range. When set for a white target,
the unit triggers on the black to white transition. When set for a black
target, the unit triggers on the white to black transition.
