To conserve reagents, remove and reinstall the reagent module only
when necessary.
When removing any EasyStat components, follow the procedures
under Replace Components in Operating the Analyzer for the compo-
nent being removed, to ensure that all reagents are purged from the
sample flow path before component removal.
It is critical that the EasyStat sensor module surfaces and electrode
exterior surfaces are completely dry before reassembly. The presence
of moisture in these areas will interfere with normal calibration and
sample analysis.
It is recommended that quality control material be analyzed after
troubleshooting to verify performance.
To remove or replace any EasyStat electrodes, follow the instructions
under Components in Operating the Analyzer.
