4.0 out of 5 stars
One way it could be better.,
This review is from: Extech 407750 30 Decibel to 130 Decibel Sound Level Meter with RS232 Computer Interface and Background Sound Absorber (Tools & Home Improvement)
Meter works as expected. I wish that it would hold the "fast" vs. "slow" setting on power-off like it holds the scale setting and other settings (it always resets to "fast" on power-off). I expect most users perform the majority of tests on the same settings, and it makes testing more error-prone to have some settings retained and others not.
