Review: Great little instrument - Bought this bit of kit to test some instruments at my work very low price decent quality of build very easy to use
Review: A Great +/- 0-10V, 0-22mA or 4-20mA Source - I was a bit dubious when I first bought one of these. But they're actually brilliant for generating +/- 0-10V, 0-22mA and 4-20mA sources. The menu is a bit confusing when you first look at it, but it doesn't take long to get the hang of it and they really are very useful pieces of equipment. 👍
