Features of the Pro 3 audio cable tester:
There are 2 rows of 4 LED's corresponding to each of the possible connector pins and one for the screen (or ground) connection. As each pin is activated, the LED's indicate all connections associated with that pin, so that short, open and crossed circuits can be easily found. The LED's also show the possibility of high resistance or leakage connections.

Memory option:
 There are 3 LED's indicating the state of the MEMORY option.
 If the MEMORY LED is on, then AudioJoG Pro automatically scans all the connections and compares against information held with just one press of the test button.
 MEMORY works in both test modes.

Test modes:
 DOUBLE ENDED - both ends of the cable under test are plugged into Pro 3.
