When leads are reversed, the LED will not light up.
Powered by two 1.5 volt AA or one 9 volt battery (not included).
For the Manaka Ion Cords, a dim light may show on the LED when the clips are connected red-to-red and black-to-black. However, these cords are still functional - the battery in the tester is overpowering the sensitive diode.
