Troubleshooting
Friction is a common problem that affects gauge accuracy. Some liquids produce corrosion in
the mechanism. Periodic inspection and maintenance provided by a Varec service contract can
prevent problems from occurring. Periodic cleaning, lubrication, and replacement of worn
parts stops trouble before it starts.
