Professional Tone Generator  & Probe Kits

Professional Tone Generator & Probe Kits

Professional tone generator and probe kits are widely used for testing electronics, electrical, building maintenance, and construction. The electrical wire tracer tone generator in these kits produces an audible tone when they detect wires or cables. Triplett’s tone & probe kits feature our recognized Fox & Hound series. Our tone generator and probe kits can trace various cable and wire types including: twisted pair, LAN, multi-conductor, telephone/alarm and unpowered electrical wire. The tone generators can produce multiple tones including warble and pulse, and they can provide an audible and visual continuity test. These test kits feature built-in LED headlights, which help illuminate dark areas, minimize fluorescent light noise; an earphone jack for quiet and noisy work areas; a bandpass filter that suppresses unwanted frequencies, and a battery cover to protect batteries. The toner and probe kit comprises test leads, pointed probes, flat blades, alligator clips, batteries, and a hard carrying case.

What is a Tone Generator and Probe?

Tone and probe kits are extremely essential for networking technicians, and they must always carry one with them. Tone generators and probes are simple tools which have evolved with time to include advanced features. An electrical tone generator is a device which converts an electrical signal into a sound signal. The sound signal can be created in various frequencies based on the application requirements. A tone generator and probe tool is used to send a signal from one end of a wire across its length to trace wiring issues or missing wires, unlabeled wires which run into various locations, and have open ends, and so on.

What are the applications of electric tone generator and probe tester?

This electrical wire tracer tone generator has diverse applications ranging from identifying network wiring issues to creating sounds for digital versions of instruments such as guitar, piano, and so on. They are used in music recording studios. They are even used in pest repellent devices which produce certain sound frequencies to get rid of mosquitoes and other pests. They are used in telecommunications as well as television cable companies to trace issues pertaining to shielding of wires.

What is an electric wire tracer?

A wire toner tracer basically checks wires that are hard to reach, deep inside walls, remotely located, or underground. A tone and probe tester and tracer kit is used to check the polarity in telecom lines, identify wire pairs and continuity in connections. There are tone generator wire tracers which can determine the wiring issues in a non-contact manner, which is through an audible sound. This offers better accuracy and reduces the possibility of false detection. This kit comprises a wire tracer or toner probe, alligator clips, batteries, and a transmitter.

How to trace wire using a toner probe?

An electrical probe tester functions in two steps to trace a wiring issue - first, wherein the tone generator with a certain audio frequency is applied to one end of a cable to produce a signal. The second step comprises emitting a sound after the signal is detected anywhere across the length of the cable. The alligator clips on the test leads of the tone generator are connected to one end of the cable which needs to be located. The signal is produced and accordingly the sound is generated through a speaker or amplifier. The good part is most of these probes are compatible with all the related devices and electrical supplies.

Any toner probe has a continuity test feature which helps check the sound as well as battery life. In this case, the test leads need to be put together and the toner needs to be set on a continuity mode. Here, you will get to know if the light and sound are dim, medium, or appropriate. Ensure there is no short before you perform the toning task. Now switch the mode to Tone from Continuity to be able to check the wire which is lost or disconnected. If it is nearby, you would hear the

Tone. This way, you need to move the probe across the location to find the suspected wire.

How far will a tone generator work?

You can adjust the sound of the tone generator to make it loud enough to be audible in a 15-20 km periphery. This depends upon the physical area and the application requirement. If the tone is light, you can add a signal ground to enhance the volume. A signal ground serves as a reference point for the other end of the toner probe. Sometimes, if you are aware of the issue with the wire and its location, such as a cut or burr, a loud sound may not be required.
