Telecommunications network line project and routine maintenance; computer network line project; engineering and maintenance work of other metal wire lines, necessary tools. The fir forest SML-XD68 Features: 1 can use MS and MR measured cable, phone cable, BNC cable, USB cable, open, short, cross, reverse, paired connections and cable break position, and in The visual display on the LCD. 2 cable crosstalk testing to address the potential failure of Suman. Can in many network lines, telephone lines, and a variety of other metal wire through the tips of the volume in the remote identification measured line you want to find, hunt up to 3000 meters long anti-interference and high sensitivity, the receiver The volume adjustment knob can adjust the sensitivity size. MS, MR, the OPEN are three ways to measure network cable, coaxial cable, telephone line, USB line length can measure cable length of 1500 meters, the length of the measuring cable and break positioning accuracy of up to 98% . 5 sentenced to open, can accurately determine the network cable Crystal Head Open in a particular endpoint (left, right, or middle). 6 voltage is too low, the low voltage display. Automatic delay off function. 8, have the self-test with automatic adjustment of the functions of the various test scenarios, the the automatic supplemental feature on the battery capacity and the ambient temperature changes. Measurable router end of the network cable is in good condition, measurements on live telephone line. Test cable types: 8P8C: UTP, E6P6C: TELCOM CABLE NPT, USB COAXIAL, F (S) TP BNC: Coaxial LCD display Features: dot matrix 128x64 size: 48x32mm Unit: m (meter), foot (feet), code ( YARDS) test cable length: 1200m accuracy: 2% (± 0.5m or ± 1.5ft) Power Specifications: 5 large capacity battery power: operating current ≤ 15mA volume: 149 × 66 × 23mm Net Weight: 140g Package: Tools the package + box weight: 600g/pc operating temperature / humidity: 0 ° C to 50 ° C / 20% -70%
