1. Press and hold TEACH for longer than 2 seconds to start the selected TEACH mode.
2. Present the target.
3. Press TEACH to teach the target. The target is taught and the sensor waits for the second target, if required by the
selected TEACH mode, or returns to Run mode.
Complete steps 4 and 5 only if prompted by the sensor for the selected TEACH mode:
4. Present the second target.
5. Press TEACH to teach the target. The target is taught and the sensor returns to Run mode.
See the Instruction Manual for detailed instructions and other available TEACH modes.
Manual Adjustments
Manually increase or decrease gain using
or
.
1. From Run mode, press either
or
one time. The current signal strength value flashes slowly.
2. Press
to decrease the sensor's gain or
to increase the sensor's gain, or press and hold
or
to rapidly
decrease or increase gain. After 1 second, the normalized signal strength flashes rapidly, the new setting is
accepted, and the sensor returns to Run mode.
Locking and Unlocking the Sensor Buttons
Use the lock and unlock feature to prevent unauthorized or accidental programming changes.
To lock or unlock the sensor using the buttons, press and hold
and immediately press
four times.
Performance Curves
Performance is based on a 90% reflectance white test card.
