A-Bug 140 Tone Probe / A-Bug 150 Tone Sender

Model 140 Tone Probe and Model 150 Tone Sender

Model 140

The A-Bug brand Model 140 Tone Probe is an advanced-technology probe that detects and amplifies audio tones in the 500 to 5000 Hz range, and is used by cable technicians for pair identification, cable pair tracing and fault location in telephone LAN and other metallic cables. The Tone Probe uses a non-metallic capacitive tip to non-intrusively detect tones without metallic contact.

Model 150

The A-Bug brand Model 150 Tone Sender is a miniature tone generator that sends a modulated two-frequency alternating tone on working or non-working pairs or individual conductors for detection with the Model 150 Tone Probe or other similar probes. It also tests lines for voltage, correct polarity and continuity (shorts, grounds and crosses); and provides talk battery for communication.

The A-Bug Tone Probe and Sender are commonly used by installers, splicers and repair technicians for:

  • Pair identification between two locations
  • Cable pair or individual conductor tracing
  • Cable identification and tracing
  • Location of faulty (open) conductors
  • Continuity testing
  • Polarity and CO battery testing
  • Indication of ringing voltages
  • Providing talk battery for communication between locations
  • Tip/ring (A/B) side identification
  • Short circuit detection
  • Line verification and condition
  • Tracing station wire
  • Grounded conductor test
  • Buried/aerial service wire identification
  • Testing for crossed conductors (contact faults)

Typical applications include:

  • Identification of individual pairs in outside plant cables at splices, terminals, cabinets, and pedestals
  • Tracing of jumper wiring in central office bays and main distribution frames
  • Tracing of station wiring, cables or key equipment terminations in equipment rooms and distribution terminals
  • Identification of drop wires and buried service wires at terminals an pedestals
  • Location of wiring in walls
  • Location of opens in wires
  • Testing of polarity and continuity in RJ-11 and RJ-45 jacks

Model 140 Tone Probe

The Model 140 Tone Probe is a hand held probe used by telephone or Lan construction, installers, and splicers to detect audio tones used for identification, cable tracing, or repair. The Model 140 will give an audible and visual indication if a tone is detected. The Model 140 detects frequencies in the range from 500 to 1000 Hertz.

  • Simple Operation- Just turn the probe on and adjust the gain knob to approximately mid position. Place the probe against the pairs in question. If tone is detected the Model 140 will give audible and visual indication. Physical contact with the pairs is not required. Once tone is detected, hold the probe tip against the wire pair and adjust the gain until the LED is barely on. Then, compare the signal strength of other wire pairs. If no stronger signal is detected, you have located the correct wire pair.
  • On/Off Switch- The Model 140 automatically stays on without having to hold the power switch down. The Model 140 will automatically shut off after approximately 5 minutes to prolong battery life.
  • LED Indicator- The LED gives a visual indication of the signal strength of the audio signals being received. By setting the gain to a point where the LED is just on, the user can visually compare the signal strength on one wire to the signal strength on different wires.
  • Speaker- The speaker provides clear audible indication of signal strength received. The rugged speaker has a Mylar cone which is water resistant.
  • Adjustable Gain Control- The gain control can be adjusted to fit most operating conditions. Increasing the gain can help the user when trying to detect weak signals. Also, increasing the gain can make the audible indication louder to overcome ambient noise. Adjusting the gain will help the user make audible and visual disrimination of the correct tone pair.
  • Headphone Jack- The headphone Jack allows the connection of standard headphones (1/8" or 3.5mm) to hear the audible indication which aids in loud ambient environments.
  • Bevel-Edged Probe Tip- allows easy insertion into wire bundles without cutting insulation.

A-Bug brand Model 150 Tone Sender

The A-Bug brand Model 150 Tone Sender is a miniature tone generator that sends a modulated two-frequency alternating tone on working or non-working pairs or individual conductors for detection with the Model 140 Tone Probe or other similar probes. It also tests lines for voltage including ringing, polarity, continuity, shorts, grounds and crosses; and also provides talk battery for communications between two locations. Two outputs are provided, an alligator clip output suitable for connection to wires or terminals, and an RJ-11 output for plugging into RJ-11 jacks. The Model 150 can send two types of tone. The factory setting is the alternating high/low (900/800 Hz) tone modulated at 2.5 Hz. If desired, an internal switch changes the output to a solid tone. The unit uses a standard 9 volt battery and battery life is typically 100 hours with an alkaline battery.

Specifications

  • Size: 2.4 x 2.2 x 1.2 inches (61 x 56 x 30 mm)
  • Weight: 4.6 oz. (130 grams) including battery
  • Operating temperature: 0 to 125 degrees F (-18 to 50 degrees C)
  • Storage temperature -40 to 140 degrees F (-4 to 60 degrees C)
  • Power: One NEDA type 1604 9V battery (alkaline recommended)
  • Battery life: 100 hours
  • Case material: Glass fiber reinforced Nylon 6/6
  • Outputs: two clips or one RJ-11 (in parallel)
  • Tone output level: +7.5 dBm typical
  • Tone output frequency: User selectable 800 Hz solid tone or 800/900 Hz alternating high/low tone modulated at 2.5 Hz
  • Output impedance: 700 ohms nominal
  • Maximum Talk current (leads shorted): 23 ma
  • LED on resistance in Continuity mode: 30 kohms (dim LED) to 3 kohms (bright LED)
