The Network Tone Probe allows you to trace cables and find cable ends, and also doubles as a telecom polarity and voltage tester. The probe requires a tone generator such as VPI's TESTER-CABLE-NTWK Network/Cable Tester in order to function.

How to Trace Live CAT5: As a tone probe, use the volume control and visible tone LED indicator to make tracing cables easy even in noisy environments.

As a voltage tester, it has LED indicators that signal the presence of voltage and the polarity of the line.

• Compatible with most available tone generators, including VPI's TESTER-CABLE-NTWK Network/Cable Tester.
• Detect line voltage as AC or DC.
• Low battery indicator.
• 2.5mm earphone connector for isolation of tone in a noisy environment.
• Lanyard cable for easy access to probe.
• Use test pins to detect voltage via alligator clips.
