How about little feature for next FW update?
VCO!
Many times i was not able to look at screen but need to tune something to the maximum value without being able to look at the screen!
So to have piezo inside multimeter producing sound that would change frequency with value change (i .e. voltage goes up, frequency as tone pitch goes up)
That way you can hook up multimeter to measure certain value, and while you are away, multimeter produces tone that pitches up or down while you are adjusting something, also resetting with delta function can set "new start" or create baseline pitch that will be your baseline (440Hz? idk).
Basically Like voltage controlled oscillator (VCO)!
It would be best to tie that to fast barograph display, or what I'm trying to say, the faster the better!
What is the opinion on this one?
