If you want to be nit-picky dead on accurate put an osciloscope across the rails. Measure the square wave on the screen and you have your voltage reading. If you don't have ready access to a 'scope and don't want to invest in one (THAT I understand) just deal with the approximation you get from a voltmeter. It's not accurate because the meter is designed to read a sine wave and give you the RMS voltage, but it will let you know if there is a signal on the rails and give you a relative feel for "how much" signal is on there. <br /> <br />Cheers, <br /> <br />Ed
