Smarttweezers ST5S-BTW LCR测试仪，蓝牙 (Version W)

Smart Tweezers™ LCR meter allows you to test various component types, including secondary components of Dissipation Factor (D), Quality Factor (Q).

This handheld also includes other functions that result in a more detailed component analysis.

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 polarityand 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 improvecomponent type identification foin-circuit tests.

Variable test signal output from 0.5 to 1.0 Vrms allows to improve test precision in different situation

e.g. for in-circuit measurement and loose leaded ceramic capacitors.
