产品功能
这是一种易于使用、价格具有竞争力的三合一工具，将故障定位仪、电缆导线管理器和采用 SmartTone™ 技术的音调发生器组合在一起。只需从任何两芯或多芯电缆的一端，即可在zui长 2500 英尺（7620 米）的距离内进行测量。易于在电气电线、线、安全电线和同轴电缆上找到离开路或短路位置的距离。结果以距离读数的形式显示，而不是显示波形，因此，它是供对时域反射测量 （TDR） 不熟悉的技术人员使用的理想工具。无需拉动新的电线或盲目地将墙壁打开，即可找到和修复电缆问题。由于在电源接通时持续进行测量，因此更易于发现间歇故障。
非常适用于卡车和仓库中的电缆存货管理，可通过快速评估需求和更精确地管理电缆存货，针对各种任务进行安排。取得的 SmartTone 技术提供了 5 种不同音调，以便对导线和线对进行精确识别，甚至在带电电缆附近。 在将导线接触在一起以及将电缆对的远端瞬时短接时，SmartTone 技术将改变所发出音频的音调。通过从探头听到的这种音调变化，能够可靠地确认正确的电缆对。如果意外地夹在一个通电线对上（高达 250VAC），那么测量工具中的电压检测功能将立即发出一个声音报警。
Power of operation 4 AA alkaline batteries, provide 50 hours Reverse Battery Protection No damage to the tester will occur if the batteries are installed backwards. Input Protection 250 V rms ac, continuous or intermittent Moisture If the tester is exposed to water, some may get inside, but it will suffer NO DAMAGE. See the moisture notes in the Maintenance section. Impedance Range 35 Ω to 330 Ω with auto-compensation within this range. Cables with an impedance outside this range will not be properly tested and may produce erratic or incorrect readings. Maximum Length 2500 feet on most cable types, and 500 feet on very lossy cables. The tester will feet on very lossy cables. The tester will display –Err if the cable is too long to be correctly measured. Representative Maximum 2500 feet: CAT-5 Twisted Pair Minimum No minimum length Minimum non-zero Length reading is 2 feet Length Accuracy ±2 feet for cables less than 10 feet ±5 feet for cables longer than 10 feet and shorter than 200 feet ±3 % and ±5 feet for cables longer than 200 feet High Voltage Detection An ac voltage of more than 5 V rms will trigger the High Voltage Warning. Measurement Rate Maximum of 4 complete measurements per second, decreasing to 2 seconds per measurement based on cable size and uniformity. VOP Adjustable from -20- to -99-, retained during power off. Default to -66- when batteries are changed. Measurement Technology Time Domain Reflectometry （TDR） with 50 Ω drive impedance, 6 V maximum pulse height. Low Battery Indicator flashes when battery voltagefalls below 4.1 V Tone Injection Approximay 1 kHz at an amplitude of 80 % of battery voltage. Variable frequency and cadence. Tone characteristic is changed as cable condition changes to “normal-open” from any other condition. Cable Type Virtually all two or more conductor cables Temperature Range Operating Storage 32 °F to 131 °F （0 °C to 55 °C） -40 °F to 158 °F （-40 °C to 70 °C） Humidity Operating Storage 0 % to 80 % 0 % to 100 % Weight 1 lb with batteries and clip leads Operating Altitude 10,000 ft max Certifications and Compliance Conformité Européenne. Conforms to relevant European Union directives. CAN/CSA-C22.2 No. 60950-1-03 CAN/CSA-C22.2 No. 1010.1-92 CSA-C22.2 No. 1010.1B-97, UL/ANSI 3111-1
