IDEAL-TEK - SMART TWEEZER ST-5S

Smart Tweezers ST-5S is a handheld LCR meter of a new concept.

It provides a perfect solution for testing and identification of Surface Mount Devices as well as
troubleshooting of complex electronic systems.
Its unique mechanical and electronic design combines a pair of precise gold-plated tweezers
and a digital LCR meter in compact, lightweight, battery powered instrument.
The probe is able to measure resistance, capacitance, inductance with high accuracy and
automatic component recognition.

Wide spectrum of additionnal functions:

• 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 TweezersTM 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).
• 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.
• Visible and audible tolerance mode allows to perform component sorting.
• Math null function allows to store a pre-measured offset and improve measurement precision.
