1. Continuity & Wiremap Testing

This function allows for quick verification of CAT5/CAT6 cable integrity. It identifies open circuits, short circuits, and miswiring, ensuring proper cable connections.

• Connect one end of the network cable to the 'CONT' port on the main unit.
• Connect the other end to the remote unit.
• Select the 'CONT' mode on the tester to initiate the wiremap test. The display will show the wiring sequence and any faults.

2. PoE Testing (DC 5-60 V)

The tester supports IEEE802.3af/at/bt standards and non-standard loads, ensuring safe and accurate PoE power delivery diagnostics.

• Connect the network cable from the PoE source to the 'OUT' port on the main unit.
• Select the 'PoE Test' mode. The display will show voltage, polarity, and standard compliance.

3. Length Measurement (5-300 m)

Accurately pinpoints cable breaks or the distance to a fault up to 300 meters, saving time during cable installations or troubleshooting.

• Connect one end of the cable to the 'IN/Length' port.
• Select the 'LENGTH' mode. The tester will display the cable length or the distance to any detected fault.

4. Port Flash (10/100/1000 Mbps)

Quickly identifies active switch ports and their duplex mode (full/half) by flashing the link LEDs on the connected switch.

• Connect the tester to a switch port using a network cable.
• Select the 'Flash' mode. The tester will send signals to make the corresponding port's LED on the switch flash, indicating its location and speed.
