福祿克 289 Si 真有效值工業用紀錄萬用錶
這台我想不用多做介紹吧, 不僅是頂級的手持萬用表, 其穩定的特色, 深受工業環境信任, 對我這位業餘人士當然是滿足囉~
The Fluke 289 Industrial Logging Multimeter is designed to solve complex problems in electronics, plant automation, power distribution, and electro-mechanical equipment;
it is loaded with powerful features so you can solve problems faster and help minimize downtime. Let the 289 be your watchdog for systems or processes while you are off doing other jobs.
- Line or battery powered; convenience for use in a lab environment or in the field
- Logging function with expanded memory for unattended monitoring of signals (TrendCapture allows users to review logged readings without a PC)
- TrendCapture graphically displays logged data session to quickly determine whether anomalies may have occurred
- Zoom on trend provides unprecedented ability to view and analyze TrendCapture data; zoom in up to 14 times
- Two terminal 50 Ω range with 1 mΩ resolution and 10 mA source current for comparing differences in motor winding resistance or contact resistance
- Low Pass filter for accurate voltage and frequency measurements at the same time on adjustable speed motor drives
- LoZ Volts – Low impedance voltage function for eliminating ghost voltages and also recommended when testing for absence or presence of live power
- Selectable AC filter (smoothing mode) helps display a steadier reading when the input signal is changing rapidly or noisy
- Compatible with optional ir3000 FC infrared connector (sold separately) which allows wireless connection to Fluke Connect mobile app
- Let your team see what you see in an instant with ShareLive™ video call (requires Fluke Connect mobile app and ir3000 FC wireless connector)
| 新型的診斷功能，可讓您發揮最大的工廠生產力 | |
| 新型的289維新世代的高性能工業用記錄式萬用電錶，主要是用於解決發生在電子、 | |
| 工廠自動化、配電與電力機械設備上的複雜問題，因此您可藉由其記錄資料能力， | |
| 以及可以在螢幕上進行圖形化重新檢視的功能，更快速地解決問題，並將停機時間降到最低。 | |
| 此後，在您為了處理其他問題而離開時，就讓新型的289作為系統或製程最忠實的守護者吧! | |
| 特性 | |
| ‧50,000位數大螢幕，搭配白色背光大型1/4VGA顯示器，可多組合顯示組資訊。 | |
| ‧TrendCapture的記錄功能，可有效地量測出設計效能的特性或監控無人監控的施工現場， | |
| ‧且無需使用PC即可重新檢視記錄的讀值。 | |
| ‧在需要從PC下載前，可記錄多達10,000筆資料的長時間讀值。 | |
| ‧有兩個端子，因此在50歐姆範圍內即有1m的解析度與10m電流源助於量測比較馬達線圈或接觸電阻。 | |
| ‧配有低通濾波器，可對可調速馬達驅動器與其他的電雜訊設備，進行精確的電壓與頻率量測。 | |
| ‧設有LoZ電壓，可消除殘留的電壓，以便進行低阻抗電壓量測功能。 | |
| ‧100kHz交流頻寬。 | |
| ‧可精確量測非線性訊號，高達10A(20A 30秒) | |
| ‧50mF電容範圍 | |
| ‧可承受8000伏特由負載切換與工業電路故障所引發的突波衝擊， | |
| ‧並符合第二版的IEC與ANSI電力安全標準。 | |
| ‧峰值擷取，可記錄快至250μs的暫態. |
關於那個289 Si標誌, 和後期289C代表中國製的不同, Si 並不是產地, 而是在1999年左右, 於日本銷售的儀器
標上 SI 代表符合使用 International System of Units (SI) 單位, 詳細內容可以看下面的網頁.
