2.Adjust the sensor or control the material pass line if necessary.

Inspect laser beam path and remove object or obstruction.

1.Tilt the sensor in the non-critical angle approximately 2-3 degrees. The non-critical angle is referenced in Figure 5-1 (Chapter 5) in the instruction manual. Monitor the QF value while adjusting the sensor.

2.Contact Beta LaserMike for additional support.

This happens when the gauge is mounted at a 90° angle to the direction of movement. Verify that the gauge is mounted properly. See the Aligning The Gauge section for the correct orientation.

If the gauge is mounted at the correct standoff distance from the product being measured, then the beams will overlap, making a single laser spot. See Appendices A-C for detailed mounting dimensions.

Verify that "Calibration Number Adjust" is set to 100 and not 0.

Make sure the Walking Threshold is set to a speed lower than the gauge is trying to measure. Set the Walking Threshold to 0 to disable this feature.

For the LS9000, the E setting must always be set to 31. Never change this setting unless specifically directed to do so by Beta LaserMike.

For the LS4000 gauge, set E to 287. For the LS8000 gauge, set E to 31.
