warranty counter

(PM-SMA)

Means of representing the wear and tear of an object, the use or consumption of a supply within the validity of a warranty.

Example:

A pump has two counters:

The pump is delivered together with a warranty that is valid for up to 6 months or 1000 operating hours. The values are checked using these counters every time a warranty claim is made (for example, if the pump breaks down).
