Portable & Lightweight Design At just 3.88 oz (110g) and compact dimensions of 3.94″ x 1.1″ x 4.13″ (10 x 2.8 x 10.5 cm), the JM-468AL easily fits in your tool bag, pocket, or belt pouch. Take it anywhere for on-site testing without adding bulk to your toolkit.

CE Certified Quality CE certification ensures this network cable tester meets European safety, health, and environmental protection standards, giving you confidence in the product’s quality and reliability.

How Network Cable Testing Works

The JM-468AL consists of two units: a main tester and a remote terminator. By connecting each end of the cable to these units, the tester sends signals through each wire pair and displays the results via LED indicators.

What the Tester Detects:

1. Continuity: Verifies all wires are properly connected end-to-end
2. Open Circuits: Identifies broken or disconnected wires
3. Short Circuits: Detects wires touching each other incorrectly
4. Crossed Wires: Shows if wire pairs are reversed or mismatched
5. Split Pairs: Identifies improper pairing that causes crosstalk

LED Display Patterns:

• Sequential lighting (1-2-3-4-5-6-7-8) indicates proper wiring
• Missing LEDs indicate open circuits
• Out-of-sequence LEDs indicate crossed wires
• Multiple LEDs lighting simultaneously indicate shorts
