### The certified curve for each pump tag, marked with the as-installed impeller diameter and the measured startup operating point, shall be placed in the operation and maintenance manual.
### The curve with the startup point marked on it is the single most useful page in the manual, because every future troubleshooting question about the pump is answered by comparing a new measurement against that mark. {note}
