Early Maintenance Feedback feature
Both the Headspace and Agilent Instrument Utilities include
the capability to alert users of upcoming maintenance needs.
This feature, called Early Maintenance Feedback, notifies
users when a counter (such as a gripper pad counter, valve
loop counter, or probe cycle counter) has reached the
specified maintenance point. After performing the required
maintenance, reset the applicable counter. Refer to the
Operation manual for details about this feature.
