FAQ

Industry best practice and standards (such as IEC 61094 and ISO 17025) recommend calibration annually (every 12 months), or more frequently if used in critical or regulated settings.

Calibration is due if:
- The annual calibration certificate has expired.
- The device has experienced physical shock, contamination, or environmental extremes.
- Measurement drift or results anomalies are observed.
- Regulatory or customer requirements stipulate recalibration intervals.Let me know if you need datasheets, links, or further configuration details!
