FAQ

Answer: It is recommended that the Bruel & Kjaer 4391-V Accelerometer be calibrated annually (once per year), or more frequently if required by critical applications or internal quality standards.

Answer:
- If the scheduled calibration interval has elapsed (typically one year).
- If the accelerometer has experienced shock, overload, or is suspected of sustaining mechanical damage.
- If measurement accuracy is questioned or if results are inconsistent compared to past measurements.
- If required by regulatory or quality system (ISO, internal policy, etc.).
- If the unit has been in storage for a long period before use.
