B. Balanced cable fault indications.
1. An intact properly polarized device will light
the green LED in the 2-T position and the red
LED in the 3-R position.
2. If #1 or sleeve is open or there is a dead
short between any two conductors, neither LED
will light.
3. If #2 or tip is open, no LED will light in the
2-T position and the red LED will light in the
3-R position if #1/sleeve and #3/ring are
intact and properly polarized.
4. If #3 or ring is open, the green LED will light
in the 2-T position and no LED will light in
the 3-R position if #1/sleeve and #2/tip are
intact and properly polarized.
5. If #1/sleeve and #2/tip are reversed and
#3/ring is intact, the red LED will light in the
2-T position. No LED's will light in the 3-R
position.
6. If #1/sleeve and #3/ring are reversed and
#2/tip is intact, the green LED will light in the
3-R position. No LED's will light in the 2-T
position.
7. If #2/tip and #3/ring are reversed and
#1/sleeve is intact, the red LED will light in
the 2-T position and the green LED will
light in the 3-R position.
C. Unbalanced device continuity and polarity:
1. In the 2-T position the green LED should light.
If the red LED lights, the circuit is reversing
the polarity. If neither LED lights then there
is either a short between #1/shield and #2/tip
or an open circuit.
2. In the 3-R position most unbalanced devices
ground these connections. Whatever the case, no
LED's should light in this position.
