im in the process of building my tps tool off one of the sticky threads. just wondering about the regulators. i bought a couple of them to test, and they were 4.98 and 5.02. tested them with different 9volts as well with no change in voltage. but just for fun i tested with a different volt meter and one of them measured right at 5.00v. is this going to throw off my reading if i use this regulator and meter? just dont want to spend the time doing it if its not going to be right.
