Perhaps what you are saying makes sense, but coming from an electronics background I have not problem using my hand held Digital Volt Meter to measure 0.2V or 350V. It is very accurate measuring either.

While a meter might (that's for purposes of discussions only) be somewhat accuracy for both small and large readings, the relevance isn't. Most gauges and meter are built to an accuracy based on the overall scale, ie, ±1% of the scale, so a 200psi gauge is accurate to ±2psi. That's fine at 100psi where it's only 2%, however even if it were equally accurate at 5psi, the error is now ±40%. So when we talk of accuracy in measurement it's both a question of precision and the relevance of the error.

As for the electronic meter, read the fine print, and you'll see the problem of using a large scale for small readings. My digital volt meter has a switch which selects a scale of LT 2v, LT20v, LT200v and GT200v. I use the smallest scale greater than what I expect toe voltage to be. If in doubt, start at max, and work my way down so I don't blow the internal fuse.
