I have found all the info on your site. Thankyou Gents

Hi Guy's Sorry. I am causing all sorts of confusion here. To clarify....This digital volt meter is a great idea. I will build my own 0-30vdc variable supply at 3 amps. very similar to what you have on your site. However instead of using analogue meters. I would like to build this digital voltmeter into it. I would also like some detailed guidance from you knowlegable gentleman as to how to change the digital meter into a digital ammeter. Your assistance would be greatly appreciated. Greg

Ante, What would the circuit look like and what value shunt resistor would be needed to enable the meter to measure 30 vdc and 3 Amps Greg
