Twisted pair cable tester Fluke LIQ-100 RJ-45 USB 305m

The Fluke LIQ-100 twisted pair cable tester verifies performance of RJ-45 and USB network cables and measures cable length up to 305 meters. It validates cable performance up to 10 Gig using frequency-based measurements, provides distance-to-fault and a wire map of the cable under test, and features built-in lithium-ion battery power for extended field use. The compact, portable design and support for LinkWare PC result management make the LIQ-100 suitable for professional technicians who need combined cable and network diagnostics.

Advantages

The Fluke LIQ-100 combines cable certification-level diagnostics with basic network tests in one handheld unit. It measures cable performance up to 10 Gigabit speeds, reports distance to fault, and generates a wire map for quick identification of miswires and shorts. Nearest-switch diagnostics show switch port information and help validate switch configuration. Additional functions include analog and digital toning, port blink, 802.1x authentication support, remote office locator compatibility, and result management via LinkWare PC. The built-in 6400 mAh lithium-ion battery provides long runtime for on-site testing.

Suitable for

• Installation and verification of RJ-45 Ethernet cabling

How to use

Connect the LIQ-100 to the cable under test using the appropriate RJ-45 or USB port. Select the desired test mode to run cable performance measurements, obtain a wire map and distance-to-fault, or perform nearest-switch diagnostics. Use toning or port blink to physically locate ports and use 802.1x checks to validate authentication where required. Save or export test results to LinkWare PC for documentation and reporting.

Usage recommendations

For reliable field results, ensure the LIQ-100 battery is sufficiently charged before extended test sessions, verify connector seating before each test, and export critical test results to LinkWare PC for archival and report generation.
