XL2 Sound Level Meter Calibration according to IEC61672

XL2 Sound Level Meter Calibration according to IEC61672
NTi Audio offers calibration services for its devices in addition to the broad range of audio, acoustic and vibration measurement solutions. Besides the calibration of individual system components, the sound level meter calibration according to IEC61672-3:2013 is now available for the XL2. The specified procedures for periodic sound level meter testing are followed and a comprehensive calibration certificate is presented.

Standards are an integral component of professional measurement technology. They ensure uniform, comparable, reproducible and documented quality. IEC61672-3 deals with "procedures for periodic testing of time-weighting and integrating sound level meters" and is an internationally recognized standard. The current version, from 2013, describes both acoustic measurements, such as noise and frequency, as well as a variety of electrical tests. During the sound level meter calibration the detailed parameters of the XL2 are recorded and compared with the limits specified in the standard.

Traceable Calibration
An essential prerequisite is that the accuracy of all measuring instruments used for each calibration is completely traceable and documented. The procedures for calibration and individual adjustment follow the provisions of the IEC17025 standard for documentation and traceability.

Comprehensive Calibration Certificate
Each sound level calibration is documented in a certificate with a unique number. All the relevant information on the verified XL2 Sound Level Meter and the measuring equipment used are listed. This is followed by the detailed measurement results and the assessment of the test.
