Today, there are two types of universal testers: digital and analog. Some digital testers have the advantage of automatic gauge selection, making them much easier to use. Always choose the highest rating of the quantity being measured if the rating selection is not automatic. Reminder: The ground wire is usually in the middle of the socket.
