Could you just confirm which of the two leds indicates which polarity of the centre pin. This is not really explicitly stated on the packaging or the tester, just indicated by the symbols on the tester.
Asked by: Anonymous
When the LED illuminates the LED has a + or a - next to it, this is the centre pin.
