Type approved software versions

National bodies that type approve sound level meters generally approve specific versions of the sound level meter software.

Updating your analyzer’s software version has no influence on measurement accuracy and in no way affects the quality of the measurement.

Therefore updating your analyzer’s software version will invalidate your calibration. This will always be the case regardless of which laboratory you have chosen to perform the calibration.
