Cable Tester
Please read these operating instructions carefully
prior to operating the unit and keep them for later use.
1 Applications
The CT-1 serves for testing standard audio cables and
therefore is a useful tool, not only for everyday stage
applications. LEDs show the contact connections of
cables with 6.3 mm plugs, XLR plugs, phono plugs,
Speakon
®
plugs (2 and 4 poles), and 5-pole DIN plugs.
The continuity tester with visual and acoustic sig-
nals offers the perfect completion for testing all other
connections.
2 Important Notes
The unit corresponds to all required directives of the
EU and is therefore marked with
G
The unit is suitable for indoor use only. Protect it
against humidity and heat (admissible ambient tem-
perature range 0 – 40 °C).
G
For cleaning only use a dry, soft cloth, never use
chemicals or water.
G
No guarantee claims for the unit and no liability for
any resulting personal damage or material damage
will be accepted if the unit is used for other purposes
than originally intended, if it is not correctly con-
nected or operated, if it is overloaded, or not re paired
in an expert way.
If the unit is to be put out of operation defini-
tively, take it to a local recycling plant for a
disposal which is not harmful to the environ-
ment.
Do not put exhausted batteries into the household
rubbish but take them to a special waste disposal
(e. g. collection container at your retailer).
3 Operation
3.1 Inserting/replacing the battery
1) Unscrew the two screws from the battery compart-
ment cover (16) and remove the cover.
2) If existing, pull out the exhausted battery and
release the contact plate.
3) Connect a 9 V battery or a corresponding recharge -
able battery to the contact plate (observe the polar-
ity!) and insert it into the battery compartment.
4) Reposition the battery compartment cover and
tighten it with the screws.
If the unit is not used for a longer period of time,
remove the battery. Thus, the unit will not be damaged
if the battery should leak.
3.2 Checking the battery
To check the charging state of the battery, set the
selector switch (17) to position BATT. CHECK. If the
LED (5) does not light up or only lights up dimly, the
battery is exhausted and should be replaced.
3.3 Testing the cable
1) Make sure that the cable to be tested does not
carry any voltage (e. g. observe that one cable end
is not connected to the amplifier).
2) Connect the plug of one cable end to one of the
jacks (6 to 10) on the left side, connect the plug of
the other cable end to one of the jacks (11 to 15) on
the right side.
3) With the rotary switch (17) successively select the
contacts of the connection jack used on the left side
of the unit. The table shows which contact corre-
sponds to the adjusted position number in each
case.
CT-1
If there is a connection from the selected contact
to a jack on the right side of the housing, the cor-
responding LED in the lower LED row (4) lights up.
The upper LED row (2) shows the connection of the
selected contact to the respective contacts of the
jack on the right side.
When using the DIN jack, the LED GND (1) lights
up additionally if the selected contact is connected
to the plug housing and the screening of the cable.
When connecting 2-pole 6.3 mm plugs, the con-
tacts 1 and 3 are connected with each other by the
plug, therefore both LEDs light up in the upper LED
row (2).
3.4 Continuity tester
It is possible to connect standard test cables (e. g. CC-
311A by MONACOR) to the two 4 mm banana jacks
.
(3) of the continuity tester. Hold the test probes to the
two ends of the cable to be tested, not carrying any
voltage. A signal sounds with existing cable con-
nection and the LED between the jacks lights up.
4 Transport
When transporting the unit, pay attention that the con-
nections are not accidentally connected by conducting
objects. Otherwise the battery will possibly be ex-
hausted the next time it is used.
