LCR-Reader MP: the Ultimate PCB Debugging Tool

With LCR-, ESR-meter, AC/DC Voltage/Current meter, Oscilloscope and Signal Generator this device covers all needs for low frequency PCB debugging.

LCR-Reader-MP recently released by Siborg Systems Inc. which joins the LCR-Reader family of handheld LCR- and ESR-meters, offers users unprecedented functionality for testing circuits and components and a record high basic accuracy of 0.1%.

The IEEE International Electron Devices Meeting (IEDM) is an annual nano- and microelectronics conference held in December since 1955. The scope covers technological breakthroughs in the areas of semiconductor and related device technologies, manufacturing, design, modeling, physics and circuit-device interaction.

Digital Multimeter LCR-Reader-MP is a continuation of the LCR-Reader line of products and features a design of combining a lightweight multimeter, and LCD display and a set of tweezers with gold-plated probes. The device is controlled using a jog-wheel navigation similar to the one used in the original Smart Tweezers ST-1. The new device offers more measurement features than any other tweezer meter uo to date. These features include: oscilloscope mode, LED/diode measurements, AC/DC voltage measurements, continuity testing, pulse counting, signal generator, super large capacitance measurements, etc. Most importantly it offers the ability to test at 100 kHz test frequency that allows for a 0.01 pF resolution for capacitance and 1 nH resolution for inductance.

Analog Capacitor ESR Tester


TallMan’s lab @ runawaybrainz.blogspot.com build a nice looking and simple analog ESR capacitor meter based on a EEVBlog forum topic.

I finally got round to making my capacitor ESR tester this week after finding a nice simple 5 transistor version by EEVBlog member Jay_Diddy_B. Unfortunately, for me, the design was only SMD so, I decided to replicate his schematic in Eagle PCB using a through hole component design.

Elektor 500ppm LCR meter case tips


NopHead wrote a review of Elektor 500ppm LCR meter:

I recently bought a 500ppm LCR meter from Elektor because I didn’t have anything for measuring inductors or the ESR (equivalent series resistance) of capacitors, both of which are important for modern electronics, particularly switch mode regulators that have become ubiquitous. It is also more accurate than any of my multimeters and has wider measurement ranges.
