Test Operations
1. Plug one end of the subject cable into the RJ45 jack on the master unit and
the other end into the RJ45 jack on the remote terminator.
2. Push and release the test button and check the results:
a. First check the 5 horizontally aligned green LED indicators (1-2,
3-6, 4-5, 7-8, shield) for integrity status:
Solid light = pair is OK
Flashing light = pair is faulty
No light = open pair
b. Simultaneously, check the 4 vertically aligned LED indicators
(short, reversed, miswire, split pairs) for the wiring faults.
c. For more detailed information about what faults are occurring in
which pairs, hold the TEST button for 2 seconds to activate
“Debug Mode”. The tester will test each pair on by one, pausing
briefly on each pair, and display the corresponding fault status.
3. After the test is done the device will automatically turns itself off.
Tone Generator Operations
1. Connect the subject cable to the RJ45 jack on the top of the master unit of
the tester. To send a tone into a patch panel, connect one end of a patch cord
to the RJ45 jack on the tester and the other end to a jack on the patch panel.
2. Generating a tone:
a. Single tone – press TONE and TEST button simultaneously and
then release both buttons before 2 seconds elapse.
b. Dual tone - press TONE and TEST button simultaneously holding
them down for more than 2 seconds.
3. Use Model 261 cable tracer or any cable tracing product in the market to
trace the subject cable. The signal reception will be strongest near the
subject cable.
4. Press either TEST or TONE to stop the generator.
Battery Replacement
When the LOW BATTERY light illuminates, the battery does not have sufficient
power to support an accurate test. At this time, you must replace it with a new
battery.
Warning
1. Do not connect the 240A to a live circuit as this may damage the tester.
2. Testing in a high frequency activated area may cause the tester to give
inaccurate readings.
3. Do not drop or get the tester wet as it may cause internal damage.
4. Do not place the tester in areas of high humidity or direct sunlight.
5. Do not open the tester or attempt to repair in case of malfunction. Please
send it back to your distributor for repair or replacement.
