Early Maintenance Feedback (EMF)

Using the EMF Counters

The user-setable EMF limits for the EMF counters enable the early
maintenance feedback to be adapted to specific user requirements. The wear
of autosampler components is dependent on the analytical conditions,
therefore, the definition of the maximum limits need to be determined based
on the specific operating conditions of the instrument.
Setting the EMF Limits
The setting of the EMF limits must be optimized over one or two maintenance
cycles. Initially, no EMF limit should be set. When instrument performance
indicates maintenance is necessary, make note of the values displayed by the
injection valve and needle movements counters. Enter these values (or values
slightly less than the displayed values) as EMF limits, and then reset the EMF
counters to zero. The next time the EMF counters exceed the new EMF limits,
the EMF flag will be displayed, providing a reminder that maintenance needs
to be scheduled.
