THE TWO MODES "ON" AND "AUTO"
THE MCTXL HAS TWO OPERATING MODES:
ON: this is the manual modus, with the "left –right" buttons you can jump from one connection to the next.
Auto: In the Auto Mode, all the connections will be tested in a sequence. You do not need to press the left right
buttons to jump from a connection to the other. This will be done automatically.
TESTING
How to test a standard balanced XLR cable:
On a standard balanced XLR cable the corresponding pins on each end of the cable are directly connected to
each other.
Plug both ends of the cable into the cable tester and turn the switch to the "on" position. If the cable is intact,
both the red and green LEDs will light up. This indicates a working connection between pin 1 on one side of
the XLR cable and pin 1 on the other side.
Now switch to position 2 and 3 with the "right" button. The respective red and green LEDs should illuminate.
A defective cable is indicated in a number of ways. If, for example, there is no connection between the XLR
cable's number 1 pins, neither of the LEDs in position 1 will illuminate. If there is a short circuit across pins,
the first LED in one of the rows will illuminate along with either the second or third LED (or both) in the row
above or below. It is also possible to test mixed cables, for example XLR to ¼ inch TRS (jack). Simply plug one
end of the cable into
the left side of the tester and the other into the right side. Switch through the various test positions with the
left/ right buttons and check the connections. Of course, to be able to evaluate the test results, it is necessary
to understand how the pins are connected to each other. The following diagrams illustrate the pin connections
of a variety of balanced and unbalanced cables.
