I have a snap on Vantage ultra among other snap on scanners and I am having trouble figuring out if this has the ability to test amperage in circuit like the Vantage pro does. The only options I see are to use an amp clamp but the Vantage pro allowed me to perform a parasitic draw test in circuit between the battery negative post and Battery negative cable. I don’t know if this is a hardware option that is no longer available or if it is a software update issue. Can someone please help me out?
