network cable tester and toner probe kit — specifically a Fluke Networks IntelliTone Pro 200.
What it’s used for:
It helps technicians find, trace, and test network cables (LAN/Ethernet wires).
Main functions:
• 🔍 Cable tracing (toning):
You plug the transmitter into a cable, and use the yellow probe to locate that exact cable among many others (very useful in racks or walls).
Cable testing:
Checks if Ethernet cables are wired correctly (detects faults like open, short, or crossed wires).
Signal detection:
The probe can detect digital or analog signals from cables.
