Press the Alignment Tool Cal button to start. (Be sure the sensor has been aligned to the scale, across the

entire length.)

Both the Alignment Tool Signal Level and Index/Limit LEDs will turn solid

green

. This starts the Gain Offset

Phase (GOP) calibration.

Move the sensor back and forth anywhere on the scale, 10mm or more. This movement adapts and ends the

GOP calibration when the Signal Level LED turns

blue

, with the Index/Limit LED solid

green

Index calibration: move the sensor back and forth across the index until both Signal Level and Index/Limit

LEDs turn

blue

. (At this step, the Index has been calibrated and the left limit is ready to be calibrated.)

Left limit calibration: move the sensor over to the “left limit” area on the scale, with both Signal Level and

Index/Limit LEDs solid

blue

. Push the Cal button. The Index/Limit LED will turn

red

. (At this step, the Left Limit

has been calibrated and the right limit is ready to be calibrated.)

Right limit calibration: Move the sensor over to the “right limit” area on the scale with Signal Level LED solid

blue

and Index/Limit LED solid

red

. Push the Cal button. (At this step, the Right Limit has been calibrated.)

Both the Signal Level and Index/Limit LEDs will quickly flash

green

5 times to indicate that calibration has

been completed.

(Note: to skip a step, push and hold the Cal button for 2 seconds until LEDs change color, then release button.)

NOTE:

Correct orientation of the scale for Left/Right Limit calibration is shown below. The

“D” datum edge from the OPS Interface Drawing is designated as the “Top” of the

scale. The Index/Limit track is also the “Top” track on a scale (tape and glass).

“D” datum edge of scale = “Top” of the scale.
