One way it could be better.
By John Calhoun
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.
