Early Maintenance Feedback
Early Maintenance Feedback
Maintenance requires the exchange of components which are subject to wear or
stress. Ideally, the frequency at which components are exchanged should be
based on the intensity of usage of the module and the analytical conditions, and
not on a predefined time interval. The early maintenance feedback (EMF) feature
monitors the usage of specific components in the instrument, and provides
feedback when the user-selectable limits have been exceeded. The visual
feedback in the user interface provides an indication that maintenance
procedures should be scheduled.
EMF Counters
EMF counters increment with use and can be assigned a maximum limit which
provides visual feedback in the user interface when the limit is exceeded. Some
counters can be reset to zero after the required maintenance procedure.
The detector provides the following EMF counters:
• Deuterium Lamp On-Time
• Number of UV lamp ignitions
Using the EMF Counters
The user-settable EMF limits for the EMF Counters enable the early maintenance
feedback to be adapted to specific user requirements. The useful maintenance
cycle is dependent on the requirements for use. Therefore, the definition of the
maximum limits need to be determined based on the specific operating
conditions of the instrument.
