Just finished our first trip with our new VMSpc and I am still smiling. I enthusiastically second all the good things everyone has said about the VMSpc. I did discover one item (battery voltage) that I wanted one decimal worth of more detail and one item (turbo boost) that had a decimal point that I would have preferred was an even number.
I suspect that others readily understood how to dictate the degree of accuracy but I could not find it referenced anywhere. As I should have known, it is a very simple adjustment. In the parameter editor, the lower left hand box is "format". This box is usually filled in with something like "%.0f" or "%.1f". I discovered that the zero represented no decimal point and the one dictates a single decimal point in the readout. Simple once you figure it out.
Hello Richard
You can expand on that reading with ' %.3f ' 3 decimal points. However, it may look like one can increase precision--but the accuracy of the reading is another matter. A fellow would need his DVM to track the same readings to verify changes.
