產(chǎn)品功能
這是一種易于使用、價(jià)格具有競爭力的三合一工具，將故障定位儀、電纜導(dǎo)線管理器和采用 SmartTone™ 技術(shù)的音頻發(fā)生器組合在一起。只需從任何兩芯或多芯電纜的一端，即可在zui長 3000 英尺（915 米）的距離內(nèi)進(jìn)行測量。易于在電氣電線、線、安全電線和同軸電纜上找到離開路或短路位置的距離。結(jié)果以距離讀數(shù)的形式顯示，而不是顯示波形，因此，它是供對(duì)時(shí)域反射測量 （TDR） 不熟悉的技術(shù)人員使用的理想工具。無需拉動(dòng)新的電線或盲目地將墻壁打開，即可找到和修復(fù)電纜問題。由于在電源接通時(shí)持續(xù)進(jìn)行測量，因此更易于發(fā)現(xiàn)間歇故障。
非常適用于卡車和倉庫中的電纜存貨管理，可通過快速評(píng)估需求和更精確地管理電纜存貨，針對(duì)各種任務(wù)進(jìn)行安排。取得的 SmartTone 技術(shù)提供了 5 種不同音調(diào)，以便對(duì)導(dǎo)線和線對(duì)進(jìn)行精確識(shí)別，甚至在帶電電纜附近。 在將導(dǎo)線接觸在一起以及將電纜對(duì)的遠(yuǎn)端瞬時(shí)短接時(shí)，SmartTone 技術(shù)將改變所發(fā)出音頻的音調(diào)。通過從探頭聽到的這種音調(diào)變化，能夠可靠地確認(rèn)正確的電纜對(duì)。如果意外地夾在一個(gè)通電線對(duì)上（高達(dá) 250VAC），那么測量工具中的電壓檢測功能將立即發(fā)出一個(gè)聲音報(bào)警。
| Power | 4 AA alkaline batteries, provide 50 hours of operation. |
| 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 information on moisture under “Maintenance”. |
| 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 certain cable types, 2000 feet on most cable types, and 500 feet on very lossy cables. The tester will display –Err if the cable is too long to be correctly measured. |
| Representative Maximum Cable Length | 2500 feet: CAT-5 Twisted Pair 2000 feet: 12/2 ac Wire 1000 feet: RG-6/U TV Coax 500 feet: RG-174/U Coax |
| Minimum Length | No minimum length Minimum non-zero 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 voltage falls 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） |
