- The annual calibration due date is approaching or has passed,
- There has been a significant impact, drop, or other physical stress to the equipment,
- The unit’s readouts seem inconsistent or produce unexpected results,
- After major repairs or component replacements,
- As recommended in the manufacturer’s user manual for preventative maintenance schedules.
