Other Possible RangeFinder Signal Degradation Factors
Two other factors that can negatively affect the RangeFinder signal are Laser Power and
Ambient Light.
Laser Power Test
If the Left (or Right) laser signal looks good, but the opposite side laser code words
periodically drop out:
1. Select left side signal and note its signal amplitude.
NOTE: The gain may have to be reduced in order to have a good
representation of the signal.
2. Select right side laser and confirm that the signal amplitude is relatively equal to the left
side signal amplitude.
A noticeable discrepancy could indicate a potential problem with the laser diode, and the unit
could report erroneous height data.
Since there are no field repairable items on the RangeFinder the unit should be replaced.
