•
Best results are achieved when the calibrator and sound measuring
instrument are given time to acclimate to the current environment.
•
For proper calibration the ambient sound level should be less than 88 dBA.
•
A non-condensing environment is required for proper measurements.
•
An annual laboratory calibration is recommended to ensure accurate
calibration results. Between laboratory calibrations, or when there is an
accuracy question, the AcoustiCal may be field checked by comparing the
output with another AcoustiCal, or reference meter with similar
specifications/accuracy.
