REMARKS:

– Please do not expect a quiet room reading to be 0 dBA. The 30 dBA – 130 dBA range is the standard usable range and an average quiet room will be around 30 dBA.
– To calibrate you will need a real external device or calibrated sound level meter as a reference, then adjust the trim value until the reading matches the reference.
