ON AND AUTO MODES
THE AHMCTXLV2 OFFERS TWO OPERATING MODES:
ON (manual mode): The individual contact connections can be specifically selected by
pressing the left/right buttons.
AUTO: In this mode, all connections are run through automatically in order.
CARRYING OUT A TEST
How to test a balanced standard 3-pin XLR cable:
In this cable type, the contacts are connected one-to-one at each end of the cable.
Connect the two cable plugs to the cable tester and move the switch into the ON position.
If the cable is OK, both the red and the green LEDs light up. This means that there is a con-
nection between Pin 1 at one end of the XLR cable and Pin 1 at the other end.
Now press the right-hand button to test Positions 2 and 3. Here again, the red and green
LEDs should light up accordingly. There are several ways of identifying a defective cable.
If for example the connection is interrupted at Pin 1 of the XLR cable, only one of the two
LEDs will light in Position 1. In the event of a short circuit between several pins, the first LED
in one of the two rows will light up at the same time as the second or third LED (or both) in
the other row.
It is also possible to test cables with different plugs, e.g. an XLR and a 6.35 mm TRS jack
plug. To do so, simply connect one end of the cable to the left-hand side of the cable tester
and the other to the right-hand side. Then use the left/right-hand buttons to run through the
test positions and check the individual connections.
In order to be able to interpret the test results correctly, you must of course know which
pins are supposed to be connected to each other.
The figure on the next page shows a wide range of different balanced and unbalanced
cables with the relevant connections.
Once the measurement operation is complete, return the switch to the OFF position.
Note: In order to save the batteries, the device switches off automatically after 180 seconds
of not being used.
