Troubleshooting
The Eclipse transmitter is designed and engineered for
trouble-free operation over a wide range of operating
conditions. Common transmitter problems are discussed
in terms of their symptoms and recommended corrective
actions. Information on how to handle material buildup
on the probe is also provided in this section.
WARNING!
Explosion hazard. Do not connect or
disconnect equipment unless power
has been switched off or the area is
known to be non-hazardous.
