FAQ

Typically, calibration is recommended once a year (annual calibration) or according to your quality system requirements.

You should calibrate the preamplifier if:
- It has been subject to mechanical shock, vibration, or exposure to harsh environments.
- There are observable changes in measurement results, noise levels, or signal quality.
- It has exceeded the recommended calibration interval (usually one year).
- After any repair or significant maintenance. Let me know if you need information on suppliers or datasheets.
