VC‑02 Portable Vibration Calibrator In vibration testing experiments and equipment condition monitoring, the measurement accuracy of sensors directly determines the reliability of data. After prolonged service or accidental impact, the sensitivity of sensors will drift, making regular calibration indispensable. The VC‑02 portable vibration calibrator integrates signal generation, excitation, a standard reference sensor, and signal acquisition and analysis. It can complete rapid calibration of multiple types of vibration sensors without additional auxiliary equipment, suiting both laboratory and field on-site deployment.
