★【 MEASURE CABLE LENGTH & ABNORMAL PAIR AND LENGTH FOR RJ45 】When you use the network cable tester rj45 to measure the cable length, the normal pair & length will be shown in the screen. If there is an open circuit, it will show the specific length range in which this situation occurs. Note that the far end cannot be connected when using pair and length measurement.

★【 CALIBRATION FUNCTION & EASY TO CARRY 】 The cat6 cable tester can do self-checking function and automatically compensates any change in battery capacity or ambient temperature. Dynamically calibrates cable length and make length measurement as accurate as 97%.Simple and easy to use, big LCD screen to display test results. Compact, lightweight, easy to carry and use.

★【 EASY TO USE & HIGH QUALITY 】Efficient, effective, reliable. A person is enough to complete network cable continuity check and cable sequence. Cat6 cable tester will indicate pair integrity of the cable. Internet wiring tester can auto time delay shut off.
