button for about two seconds – until the
Power/Cal. LED starts blinking slowly.
B B2 2..2 2..2 2 Move the sensor 50mm to perform Gain /
Offset / Phase calibration. Move the sensor
back and forth if your scale has <50mm of
measuring length. After calibration both
limit LED’s come on steady.
B B2 2..2 2..3 3 Move the sensor to an area of the scale
away from the index and limit markers.
Push the Cal. button once quickly. The
Power/Cal. LED will start blinking quickly.
B B2 2..2 2..4 4 Move the sensor over the index up to 20
passes (one pass is a cycle back and
forth). The Left Limit LED will start blinking
quickly. (Note: if the sensor is positioned
over the left limit marker, the Left Limit LED
