Metra offers factory calibrations for vibration transducers, instruments and measuring chains consisting of sensor and amplifier. In this case the calibration is the responsibility of the performing calibration lab. Factory calibration service is not accredited and therefore not covered by the EA MLA (European co-operation for Accreditation Multilateral Agreement), nor is it traceable. Factory calibration includes the issuance of a non-accredited calibration report on which the reference standards and the measured values are listed.
The picture shows a view of our calibration laboratory. On the left is a long stroke low frequency vibration table, Next to it is an air bearing medium and high frequency vibration exciter, in the middle the vibration control system and on the right hand side of the medium frequency vibration exciter for heavy objects. The frequency range of our calibration equipment is from 0.2 Hz to 20 kHz.
