Established LCR Meter Goes Multi Purpose

Offering a basic accuracy of 0.1%, test frequencies up to 100 kHz, the latest version of the Siborg Systems LCR meter, the  LCR-Reader-MP, offers an array of new multi-purpose features the likes of ac/dc voltage measurements, diode and LED test, frequency measurements, oscilloscope mode and a few others. It is suited for measuring large capacitances up to 600 mF.           


The LCR-Reader-MP becomes even more powerful when used with the LCR-Reader Probe Connector. The device becomes a complete probe station and can check waveforms at various nodes on the Printed Circuit Board. The LCR-Reader Probe Connector comes with five attachments for various applications; it allows LCR-Reader and Smart Tweezers to measure components larger than the allowable size between the tweezers' tips.

Industrial Ethernet Solutions from ADI Chronous™ Available Now from Digi-Key

ADI’s Chronous portfolio of edge-to-enterprise Industrial Ethernet connectivity solutions is designed to accelerate your path to Industry 4.0. The compatible and interoperable Industrial connectivity products enable best-in-class performance.


Oscilloscope mode allows users to analyze voltage waveforms with frequencies up to 100 kHz on active circuit boards. The recently released LCR-Reader Probe Connector makes the device even more powerful by allowing it to check waveforms at various nodes on the board quickly and easily.


A summary of features is as follows:

•Automatic LCR, ESR and Diode/LED measurement

•Basic accuracy better than 0.1%

•AC/DC voltage measurement up to 15 V

•Oscilloscope Transient Voltage display for up to 100 kHz

•Measurement of Frequency, Pulse period, Duty Cycle up to 400 kHz

•Signal Generator: Sine, Rectangle, Triangle pulse shapes up to 100 kHz

•Li-Ion Battery, USB Charger

•Diode/LED and Continuity test

•Two Test Signal levels, Automatic Test Signal Reduction to 0.1 V for in-circuit measurement

•Easy Short/Open Calibration, Offset Removal

•Handling of components as small as 0201 size (about 0.3 mm)

•Display of active and reactive impedance components

•Just 2 Oz (60 grams) weight


Drawbacks of the new model: maximum test signal available is 0.65 Vrms, that is not enough for reliable evaluation of some ceramic capacitors resulting in a lower than actual capacitance values. Another issue is a rather high test signal source resistance of 1 kOhm.


Physically, the new device is larger and twice as heavy of the original LCR-Reader and the latest model of Smart Tweezers ST-5S, but the larger size allows for a bigger screen with better readability for results and icons.


The new LCR-Reader MP will be available for sale after September 1, 2017 with an introductory offer of $388.99 each. Pre-orders are available and will be shipped as soon as the devices become available. For more details, visit the Siborg Systems website.
