If benching dimensions cannot be provided, proper sensor alignment may require minor
adjustments to the sensor position with respect to the scale. This can be performed easily
using the LED alignment indicators, as illustrated below.
The red, yellow, or green LED will light depending on sensor alignment. Slowly move the sensor
by allowing it to slide on the mounting surface until the green or Proper Alignment LED, is
illuminated. Optimal alignment will be displayed as a “Bright Green” LED.
IIM MP PO OR RT TA AN NT T: Confirm that the Proper Alignment LED blinks when passing over the index.
If not, readjust the sensor in the Y direction and repeat the above procedure. When alignment is
completed, tighten the sensor mounting screws (0.37Nm [3.3 inch-lbs.] maximum torque).

Confirm proper alignment over
the full range of motion.
The “Proper Alignment” LED
must remain on over the entire
range. If not aligned over the
entire range of motion, loosen
the sensor mounting screws
and repeat step 5.

This procedure must be completed for
proper system operation each time the
sensor is aligned or if the SmartPrecision
electronics module is replaced
Position the sensor at
least 7mm (1/4”)
away from the index
mark on the scale.
Next, push the
Index/Calibration
button inside the
module with a small
diameter shaft, such
as a bare cotton swab.
The Power/ Calibration indicator will flash continu-
ously. Move the scale past the sensor in both
directions so that the index mark passes under
the sensor. When the calibration procedure is
complete, the Power/Calibration indicator stops
flashing.
