Note: 

Saving a service profile or plot file from the instrument console can

require as much as 150 MB of file space.

4.5 Configuring maintenance warnings

Maintenance counters provide information about real-time usage that can help you
determine when to schedule routine maintenance for specific components. You can
specify usage thresholds and maintenance warnings that alert you when a
component reaches a specified threshold. Thus you can minimize unexpected failures
and unscheduled downtime during important work. For information explaining how to
specify maintenance warnings, consult the Waters console Help.
