Possible error cause
Measure
PLB
(implausible measurement
values)
Laser beam interruption
Laser spot must always be incident on the reflector.
Laser spot outside of reflector
Traverse rate < 10 m/s?
Measurement range for maximum distance
exceeded
Restrict traversing path or select AMS with larger
measurement range.
Velocity greater than 10 m/s
Reduce velocity.
Ambient temperature far outside of the permissible
range (TMP display; PLB)
Select AMS with heating or ensure cooling.
ATT
(insufficient received signal
level)
Reflector soiled
Clean reflector or glass lens.
Glass lens of the AMS soiled
Performance reduction due to snow, rain, fog, con-
densing vapor, or heavily polluted air (oil mist, dust)
Optimize usage conditions.
Laser spot only partially on the reflector
Check alignment.
Protective foil on the reflector
Remove protective foil from reflector.
