Installing the batteries It is recommended to check the battery prior to testing cables. To test the battery, do the following: 1. Lift the battery compartment cover by pressing the locking tab and removing the cover. 2. Insert the terminals of the snap connector onto the battery. 3. Place the battery into the battery compartment making sure to place the cables underneath the battery. 4. Replace the battery compartment cover and press down until the lock clicks, locking it into place.
Operating the cable tester Testing cables: 1. Plug the connectors of the cable into the corresponding jacks on either side of the cable tester. 2. Set the Power Switch on the sender to the ON position. The power LED will glow red. The first three LEDs will light in sequence indicating that batteries are installed in both battery compartments. Note: The flashing LEDs at this point do not indicate cable continuity. They only indicate that batteries are installed into both sender and receiver. 3.
5. To change the flashing speed of the LEDs, set the speed selector to fast, medium, or slow. Testing long cables that have been installed through walls or ceilings: 6. The sender and receiver can be separated by sliding them apart. Connect each side to the cable to be tested. 7. The pin indicator LEDs will flash on both sides to show each operator the status of each pin’s continuity. Reading the LED indicators: The pin indicator LEDs should flash in sequence from 1 – 8.
None of the LEDs light up and there is no beep PIN 1 is faulty or damaged. PIN 1 needs to be connected in order for the CBT-MF to begin testing the other pins. The number of LEDs that light up depend on the number of pins in the cable A 5-pin cable will illuminate LEDs 1 through 5. The other LEDs will not light up. LEDs light up in order There is good continuity on each pin.
Manually testing cables 1. Plug the banana plugs of the leads into the corresponding red and black jacks on the front panel of the cable tester. 2. Touch each lead to the corresponding pin on either end of the cable. 3. A lit LED accompanied by a beep indicates good connectivity and continuity. Using test tones 1. Switch the Cable Test/Tone Test selector on the receiver to the Tone Test position. The power LED will glow red. 2.
