Calibration is needed if:
- The device is due for its scheduled calibration (e.g., annually)
- The photo tachometer has been exposed to mechanical impacts, electrical surges, or environmental extremes
- Unusual or inconsistent readouts are observed
- You are using the instrument in a regulated environment requiring traceable measurements If you need any further details or documentation, please let me know!
