Factory service on the calibrator
3M Quest Technologies recommends checking the performance and precision of your
calibrator on an annual basis by sending it to a factory-authorized service center.
The AcoustiCal is calibrated at Quest Technologies laboratory, a 3M company, with a
Type L standard microphone and with special instrumentation traceable to NIST. The
calibrators are very stable; however, they are used to calibrate other equipment, and
should be checked periodically against laboratory standards.
