This is a question to those who have tried both 30v analog voltmeter and Digital.
I have this 30V Digital Voltmeter that I want to pair to my LM317 variable voltage regulator...
Anything around 3V and above looks ok - there's that red display lighting up, but when the voltages are lesser than 3V, the display starts to turn off... (there's only two wires on this voltmeter, positive and negative.).. I needed it to display if its running 1v or 2v or 2.5v...
What I'm curious about is that...
Does this problem exist in 30V analog voltmeters?
And, do other 30v digital voltmeters have the same limitation?
