The new LCR-Reader, the newest model in the Smart Tweezers LCR-meter family

The new design keeps up with Smart Tweezers tradition of an accurate LCR-meter merged with a set of tweezers. The LCR-Reader is smaller and lighter than previous models, while still maintaining a 1% basic accuracy.

Before the release, the new device was showing variations while trying to reach the 1% basic accuracy objective. This problem was fixed by calibrating each unit using the Calibration Fixture.

“We are very happy with the new device. Customer satisfaction is our main priority.” said Michael Obrecht, the Director of Research and Development at Siborg, “Therefore we took additional measures to ensure high measurement accuracy of the LCR-Reader before we start mass production of this model. Basic accuracy of 1% was our target and we eventually have been able to achieve it.”

The most obvious differences between the LCR-Reader and previous Smart Tweezers, from first glance, is the size and the new high-contrast LCD screen. Still available are such features as;

  • automatic Capacitance, Resistance and Inductance measurements
  • ESR measurements
  • 1% basic accuracy
  • ergonomic, one-handed design, now with only 1 oz. weight
  • one button navigation
  • test signal amplitude of 0.5 Vrms
  • automatically selected test frequency
  • Li-Ion battery with micro-USB charging  (cable not included)

The one handed navigation button allows users to easily switch between measurement modes, from Automatic to Inductance, Resistance, Capacitance and ESR modes.

AM indicates Automatic Mode, ‘L’ indicates that the component under test is an inductor, the value 104.8 uH is the main impedance value, ‘Rs’ indicates parasitic series resistance of the inductor. 10 kHz is the test frequency being used. The bottom right hand corner provides an indication of battery power remaining.

While creating a device with a lower cost, some of the features found on Smart Tweezers had to be left out, including; semi-automatic offset subtraction, component sorting, open circuit detection and continuity and diode testing.

The new LCR-Reader still offers the same functionality and easy-to-use experience of previous Smart Tweezers, but the new upgrades will maximize these features, while offering a lower-priced device.

LCR-Reader Delayed for Firmware Revision

// July 31st, 2013 // No Comments » // LCR-Reader, News

With the approaching targeted release date of the new LCR-Reader, Siborg Systems has to review the firmware to ensure that the devices are working at their best.

After the first few hundred models were produced, inconsistencies between each device reaching the projected 1% basic accuracy. This problem is due to a variation of component values on different PCBs,  which Siborg found is easily solved by individually calibrating each and every PCB, using a special calibration fixture.

“Customer satisfaction is our main priority,” says the Director of Research and Development at Siborg Systems Inc., Michael Obrecht, “Therefore we would like to ensure a high measurement accuracy of the LCR-Reader before we start mass production of this popular LCR-meter of Smart Tweezers family. Basic accuracy of 1% is our target and we will do our best to achieve it.”

The new, lighter and cheaper model of Smart Tweezers LCR-meter, the LCR-Reader is scheduled to be available this summer.

A Sneak Peek into New Model of Smart Tweezers LCR-meter with Half the Weight, at Half the Price

// April 2nd, 2013 // No Comments » // LCR-Reader, News

Designed specifically for Surface Mount Technology (SMT), Smart Tweezers are a pioneer in handheld LCR-meters. With a compact design that integrates a set of tweezers, a small display, and an LCR-meter, Smart Tweezers simplifies evaluating and identifying components. The unit’s 2 oz. slender design is easily held and operated with one hand, leaving the other free for taking notes or using other tools, and has been proven as winning combination of tools, currently being used by many major high-tech companies and customers worldwide.


Although Smart Tweezers popularity has grown exponentially over the years, the high price tag can range from $300 to $700 depending on the region and seller. The size of the screen, and overcrowding has also become a problem for some customers on the ST5 model. Even with accessibility and worldwide acclaim, the price leaves the device out of reach for hobbyists and casual users. Siborg had attempted making an alternative model of the device with a lower price, without a 1 Volt test signal option, but the price cut appeared to be only 20% and did not change the market picture overall.

Fig. 1

Fig. 1

A prototype for the new model has emerged (Fig 1.) that features half the weight and half the size of previous Smart Tweezers, but also a much lower manufacturing cost.. Development on this new model began nearly a year ago, based on new microchips and a new idea of simplifying the circuit without losing the accuracy that has become synonymous with Smart Tweezers.


Siborg’s new LCR-Reader is about half the size of current Smart Tweezers and is able to charge the Li-Ion battery via USB. Although similar in design and features, like the gold-plated tweezer tips, the new LCR-Reader features a 1% basic accuracy (the same as the previous ST2 model), a one-button navigation which turns the device power on or off, as well as mode selection; ‘A’ automatic, ‘L’ Inductance, ‘C’ Capacitance, ‘R’ Resistance and ‘ESR’ Equivalent Series Resistance. The new device still offers fully automatic measurements, with the test frequency adjusted according to the component type, test signal amplitude is 0.5 Volts.

Figure 2 shows an example of the device measuring inductance, where AM shows the measurement in ‘Automatic Mode’, ‘Rs’ indicates the parasitic series resistor of the inductance, 10 kHz as the test frequency, L proves that the component is an inductance, and 104.8 uH is the inductance value in micro-Henries, and a battery indication of the charge.


The new LCR-Reader is projected to be available in the summer, estimating sales to be four time more compared to the previous sales of the ST5 model.
