Using the CT-3
Example 1.
A. Connect an XLR cable from one side of the Ct3 (the Sender) to the other side
(the receiver).
B. Switch ON the Sender (E), if a battery is installed you should see the first
yellow LED’s lighting in sequence and then the other 5 LED’s not being lit at all.
Note if no cable is connected to the SENDER the Yellow LED’s would not light
up.
C. Switch ON the Receiver (G), if a battery is installed you will see the 3
GREEN LED’s lighting in the same sequence as the YELLOW LED’s in the
Sender side, you will also hear a BEEP sound when PIN1 is detected. (As long
as the cable is not faulty). Please note, the Cable MUST have at least PIN1
connected for the Ct3 to operate properly. You will immediately know that PIN1
is faulty if no sound or lights are working on the Ct3 when you are testing a
cable.
In this way you are now able to split the Ct3 in half (Sender and receiver) and
still see if the cable is working properly by only looking at one side of the tester
(the receiver side).
The order in which PINS are shown in the receiver side (the GREEN LED’s) is
the order in which the PINS (or wires) are being tested and connected).
If for example the XLR cable is wired 1 3 2 instead of 1 2 3 you would first
HEAR the BEEP when PIN1 is connected and then you would see PIN 3 and
then PIN 2. You would then know that the cable is not wired properly.
If for example the XLR cable is faulty with PIN 2 not connected. You would hear
the BEEP for PIN 1 (and see the GREEN PIN 1 LED lit) you would then not see
LED 2 light up and then LED 3 would light up.
