FAQs

Q1: Do I need to strip the wire insulation to track it?

A: No, you do not. Specifically, this device utilizes advanced non-destructive tracking technology. Therefore, the probe detects the internal signal through the rubber jacket perfectly. Consequently, your existing network cables remain completely safe and intact.

Q2: Will it work if the server room is extremely noisy?

A: Yes, it absolutely will. We designed this receiver with a dedicated headphone jack. Furthermore, it features an adjustable volume knob. Thus, you can plug in earphones and listen to the tone clearly amidst loud servers.

Q3: Can it distinguish between different types of cables?

A: Yes, it certainly can. First, it easily distinguishes telephone lines from Ethernet cables. Additionally, it verifies correct wiring sequences using the 9 LED indicators. Therefore, network technicians can map out complex wiring architectures accurately.

Q4: How does the open and short circuit test work?

A: Basically, you connect the transmitter to the questionable cable. Next, you activate the testing mode. If the wire is broken completely, the LED indicators will identify the exact open circuit. Consequently, it makes troubleshooting drastically faster.
