The InstallMates Tone Generator & Amplifier probe is a professional tool used to test and troubleshoot RJ11 cables and individual wires. It can be used to easily identify and trace individual wires or cables within a bundle or group and can perform continuity testing.

Benefits

• The tester is comprised of a Tone Generator and an Amplifier Probe with sensing tip. The Amplifier Probe is used to detect the presence of the tone on a wire that was sent by the Tone Generator. This can be used to detect continuity in a single wire and can test for breakage points along a wire's length. Additionally, it can be used to identify individual wires within a bundle. The insulated inductive probe tip prevents shorting conductors.
• The Tone Generator unit has a (3) position toggle switch that turns the unit on in "Tone" or "Continuity" mode. A metal sheath around the switch prevents it from being accidentally turned on or off. 
• A 3-colour LED is used to indicate line polarity, continuity, and phone line condition
• The Amplifier Probe unit has an adjustable volume control, a speaker, and a 3.5 mm headphone jack for multiple sound options
• Both the Tone Generator and Amplifier Probe units are constructed of plastic and are powered by a 9V battery (Two 9V alkaline batteries are included)
