The MTC40 Tone and Probe generator traces cables using a tone generator connected on one side and at the other end the probe. This tests even when cables are in a bundle. It is easily used to verify cable continuity, pair condition, line polarity and voltage in networking cabling systems for CAT5, coax and modular telephone lines.

• RJ11 modular connectors
• Built-in speaker on probe with sensitivity control
• Traces & identifies wires / cables in a bundle or group
• Insulated inductive probe tip prevents shorting conductors
• Tests include wire trace / continuity test clear / busy ringing line test and tip/ring identification
