产品简介
产品性能和技术指标
Smart Tweezers智能镊子式量表是一种全新概念的便携式LCR测试表。它为复杂电子系统的故障检测和贴片元器件的检验及分类提供了一个的解决方法。
精巧的镀金镊子和数字式LCR测试表组成的小巧，轻便的测试工具堪称机械和电子设计结合的又一个杰作。高精度的自动识别功能为频繁的测量电阻、电容、电感和电压提供了一个选择。
智能镊子式量表在电子行业生产，检验，检修和研发过程中被广泛运用。
方便地测量贴片元器件
因为贴片元器件通常都比较微小而且没有引线，所以在电子行业中检测和分类这类贴片元器件比常规元器件要困难的多。
Smart Tweezers智能镊子式量表的*设计对识别和分类这类贴片元件提供了方便。使用单手操作，智能镊子式的 LCR 探针能够很容易地夹住并有效接触小到0201的贴片元器件。这种探针同时也能测量由于引线过短而不能使用常规测量仪表测量的元器件。
自动的测量功能
Smart Tweezers智能镊子式量表可以自动辨别元器件的类型（电阻、电容、电感），并可根据被测元器件的数值自动调整测试量程以获得准确的读数。在液晶显示器上，会清晰地显示出被测元器件的种类，主要读数，次要读数以及测量条件。
主要显示位于显示器的，用于显示当前主要读数。次要显示位于显示器的上端。用于显示当前次要读数。比如，当测量电容时，主要显示为显示电容值，次要显示为显示ESR（等效串联电阻）。条形图表位于显示器的下端。用于模拟显示当前主要读数。
Smart Tweezers™ LCR meter allows to test various component types, including secondary components of Dissipation Factor (D), Quality Factor (Q).
The built-in Equivalent Series Resistance (ESR) mode helps you better understａnd the inherent resistance - behavior typically found in capacitors across selected frequencies.
In its DIODE mode Smart Tweezers™ tests diode polarity and indicates if it is short.
Smart Tweezers™ has a continuity detector. Variable beeper sounds for resistance reading below set thresholds. Additionally, this function helps to locate shorted conductors (e.g. on a PCB).
In manual modes Smart Tweezers™ measures a specific circuit parameter — L, C, R, Z or ESR. Manual modes also improves component type identification for in-circuit tests.
Variable test signal output from 0.25 to 1.0Vrms allows to improve test precision in different situation e.g. for in-circuit measurement and loose leaded ceramic capacitors.
Visible and audible tolerance mode allows to perform component sorting.
Math null function allows to store a pre-measured offset ａnd improve measurement precision.
