>>I don't quite understand this since, when calibrating with Avia or DVE, the readout, either digital or analog, goes to it's reading and stays there

You must not have dogs in the house. Test tones make the dogs bark... dog barking makes the SPL change... changing SPL makes the digital hard to read.

It's even worse when the dogs are not matched and bark at different volumes... I get sort of a "WOOF woof WOOF woof WOOF" superimposed on the test tones. Needless to say, I went analog.
