‡ If either sensor head moves out of position, do all adjustments, including beam
alignment, from the beginning.
Refer to the instruction manual of LA-305 for more details of beam alignment of sensor heads
Calibrating analog output
‡ The analog voltage output relates to the span and the shift adjustments as in
WKH ÀJXUH EHORZ
How to calibrate the output into 1 to 5V
*1
1. Block the whole beam to enter into the
darkest condition and set the output at
1V with the shift adjuster.
2. Allow the whole beam to be received to
enter into the lightest condition and set
the output at 5V with the span adjuster.
3. For more accurate calibration, repeat 1
and 2.

Further use of shift adjuster
‡ If you want to change the output voltage value after the calibration, the shift
adjuster enables you to shift the analog voltage up or down within about ±0.5V.
(e.g.) To shift the analog voltage from 2.51V to 3V with a certain amount of beam blockage
Collimated beam

(Application) When two sensor heads are used for width measurement the shift adjuster can
eliminate the need to move the sensor heads during set-up.

Adjusting HIGH & LOW output levels (Two independent outputs)
HIGH output threshold level
Block as much of the beam for which you want
the HIGH output. Turn the HIGH adjuster to just
before the point where the HIGH operation indi-
cator lights up. The threshold level increases as
the adjuster is turned clockwise.
LOW output threshold level
Again, block as little of the beam for which you
RU
want the LOW output. Turn the LOW adjuster to
just before the point where the LOW operation
indicator lights up. The threshold level increases
as the adjuster is turned clockwise.
