Step

Action

1. To start calibration, press and hold the Cal. button for about two seconds until the Power/Cal.

LED starts blinking slowly.

2. Move the sensor 50mm to perform Gain/Offset/Phase calibration. Move the sensor back and

forth if scale has <50mm of measuring length.
Result: After calibration both limit LEDs come on steady.

3. Move the sensor to an area of the scale away from the index and limit markers. Press the Cal.

button once quickly.
Result: The Power/Cal LED will start blinking quickly.

4. Move the sensor over the index up to 20 passes (one pass is a single cycle back and forth).

Result: The Left Limit LED will start blinking quickly.
Note: If the sensor is positioned over the left limit marker, the Left Limit LED will come on
steady.

5. Move the sensor over the left limit marker and press the Cal. button once quickly.

Result: The Right Limit LED will start blinking.
Note: if the sensor is positioned over the right limit marker, the Right Limit LED will come on
steady.

6. Move the sensor over the right limit marker and press the Cal. button once quickly.

Result: All LEDs will flash together twice to indicate that setup is completed.

7. The encoder is now ready for connection to the controller for use in servo control.

Note: To skip any portion of this calibration and move to the next procedure, press and hold the

Cal. button for two seconds.
