Time-Based and Meter-Based Work Tasks
The two ways a Work Task can recur — on a schedule, or on equipment usage.
Every Work Task has a Mode that determines what triggers its next occurrence: time or a piece of equipment's usage.
Time-based
A time-based Work Task repeats on a schedule — daily, weekly, monthly, or another fixed or variable interval you set. This is the right mode for maintenance that's due on a calendar cadence regardless of how much a piece of equipment has actually been used, like a quarterly fire-extinguisher inspection.
Meter-based
A meter-based Work Task repeats based on equipment usage rather than the calendar — for example, "every 500 run-hours" or another meter threshold tied to the equipment. This is the right mode when wear depends on usage, not time, like an engine service interval.
Instruction Set
A Work Task can carry an optional Instruction Set — guidance attached to the task that describes what the person completing the occurrence should actually do. Not every task needs one; it's there for maintenance that benefits from a documented procedure.
Choosing a mode
You can't mix both triggers on a single Work Task — a task is either time-based or meter-based. If a piece of equipment needs both a calendar check and a usage-based service, that's typically set up as two separate Work Tasks.
