Offset Calibration Board for Smart Tweezers® and Colibri

Siborg has released an Offset Calibration Board for Smart Tweezers and Colibri. This dummy PCB aides in finding offset values by using holes drilled at variable widths. These holes represent different sized components (0201, 0402, etc.)

To use the Offset Board, set the Smart Tweezers or Colibri device to 10kHz and place the tips in the respective holes to the component being measured. The LCR-meter will display the actual offset capacitance; this value can then be subtracted from the component's measured value.

The previous method of estimating the width of the component using the tips was inaccurate compared to using the Offset Calibration Board.

The Smart Tweezers Offset Calibration Board is available in the LCR-Reader Store and is included in Smart Tweezers Pro and Plus task kits.

Kelvin Probe Connector for LCR-Reader and Smart Tweezers

The Kelvin Probe Connector is a shielded two-wire probe connector for LCR-Reader and Smart Tweezers that turns either device into a Probe Station. The shielded two-wire connection eliminates virtually all offsets due to parasitics between the wires. The connector also allows the devices to measure components that normally do not fit between the tweezers' tips. Read more here


There are two additional probes for the Kelvin Probe Connector: a 124 mm Fine Pin Probe and a 73mm Extra-Fine Pin Probe for more accurate probing. These probes connect to the Kelvin Probe Connector using the 4mm multimeter jack plugs and can be found in the LCR-Reader Store.

New SMD Multimeter Test Tweezers

Siborg is offering a new device for multimeters: the SMD Multimeter Test Tweezer. This new device connects to a pre-existing multimeter and works as tweezer probes. Testing SMDs can be time consuming while working with long wire leads; SMD Multimeter Test Tweezers simplifies the process by using tweezers as probes.

New LCR-Reader and Smart Tweezers Calibration Fixture

Siborg has released a new calibration fixture that allows for LCR-Reader and all models of Smart Tweezers LCR-meters to be calibrated. Most importantly, this calibration fixture will give the LCR-Reader an NIST Traceable Calibration Certificate.
The new fixture uses a 4-wire connection to the devices, which produces less noise than the previously used 2-wire connections.The calibration fixture uses 14 known components that lay within the measurement ranges of LCR-Reader and Smart Tweezers. When a device is connected, a simple press of the button on the fixture signals a different component. The measurement values are displayed on the LCR-meters display, where the values measured can be compared to the known values of the components.
Most importantly, the LCR-Reader can now be accompanied with an NIST traceable calibration certificate for companies that require their test equipment to be periodically calibrated.

New Smart Tweezers and LCR-Reader Task Kits in the LCR-Reader Store

Siborg Systems Inc. has recently launched the newly redesigned LCR-Reader Store! The new store allows customers to read about the products before adding them to a cart. For the new launch, Siborg has begun offering 'Task Kits'; a Smart Tweezers ST-5S or LCR-Reader device with spare or replacement parts. Each kit is a pre-assembled combination that offers customers a better price that ordering each piece separately. An example of the kits: An LCR-Reader with spare probes, bent probes and a charger, or an ST-5S with a replacement battery and precision tips. There is nearly every combination for each device. Come visit the New LCR-Reader Store and see for yourself!

Smart LED Test Tweezers: Multi-function Test Device Now Available

Smart LED Test Tweezers are the newest product from Siborg Systems Inc. This device makes easy work of testing LEDs, shorts, fuses and other micro-electronic components. The device can be used as probes for a multimeter using the included cable.

Learn more about the Smart LED Test Tweezers here.

New Bent Tips

Siborg has released a new 'bent tip' for Smart Tweezers and LCR-Reader. This design is more ergonomic for use over longer periods of time by meeting the component at a more comfortable angle compared to the straight tips. The devices will still be equipped with the straight tips, with the bent tip design as an optional add-on.

Instant Evaluations With Just One Touch

The title says it all, Smart Tweezers will show you component value right when you touch it, no adjustments needed to the component type, test frequency, test signal, etc. Not only will it show the main impedance component L, C or R but also the parasitics, such as R for L, C and C for R.

Built for Simplicity

LCR-Reader is twice as light as Smart Tweezers ST-5 and also powered by Li-Ion rechargeable battery with a micro-USB charger connector. Basic accuracy of the new device is about 0.5% which is not as good as that of Smart Tweezers ST5 (0.2%) but about exceeds that of previous models of Smart Tweezers ST-1, ST-2 and ST-3. It also has gold-plated stainless steel twezer tips. There is just one button that turns the device on and allows to change the measurement mode by a single button push: A (automatic), L (inductance), C (capacitance), R (resistance), and ESR (equivalent series resistance). All measurements are done automatically, test signal amplitude is fixed at 0.5 Volts, test frequency is automatically adjusted according to the component type and value. Similarly to Smart Tweezers, LCR-Reader in addition to the the main impedance component L, C or R it will also show the parasitics, such as R for L, C and C for R.
One of the problems with Smart Tweezers LCR-meter has been the price point. Depending on the region and resellers, Smart Tweezers can be from $300 to $700. Criticism about the screen being crowded has also been sounded on the ST5 model. For companies and professionals using Smart Tweezers, there are few issues, but for the everyday hobbyist, the price point is far too high. Siborg had attempted creating a new device with a lower price (not featuring a 1 Volt test signal) but the price cut was only 20%, and would not affect the overall market.
Around a year ago, development of the LCR-Reader began, based on the availability of new microchips and ideas of how to simplify the circuit without losing much of the accuracy. The result evolved into a physically smaller and lighter device and cheaper manufacturing cost (compared to the Smart Tweezers LCR-meter).
The new LCR-Reader is powered by a Li-Ion battery, rechargeable via micro-USB. The device features a lower weight, with about 0.5% basic accuracy. Similarities to the Smart Tweezers models include the gold-plated tweezer tips that have attributed to Smart Tweezers identifiable design, a one-button navigation, and a Li-Ion battery that charges via micro-USB. The new device features a 0.5% basic accuracy, which is slightly lower than the ST5 model, but the same as the ST2 model. The button navigation provides a simple touch solution to switching modes of operation; A (Automatic component recognition), R (Resistance), L (Inductance), C (Capacitance), and ESR (Equivalent Series Resistance). All measurements are automatic, test signal amplitude is 0.5 Vrms, test frequency is automatically selected according to the component type and value.

The image to the left shows an example of the device's screen while measuring. AM shows that the LCR-Reader is measuring in Automatic Mode, Rs is the parasitic series resistance of the non-ideal inductor, 10 kHz is the test frequency being used, L shows that the component under evaluation is an inductance and 104.8 uH shows the inductance value in micro-Henries, the battery icon shows its charge level.

Planned for a summer launch, the new device's estimated sales is four-fold compared to the ST5 model sales.

The Colibri: Variable Test Frequencies

The Colibri is the model right between Smart Tweezers and the LCR-Reader. Built from the LCR-Reader, the Colibri offers a 0.5% basic accuracy, lower price, and easy-to-use design but allows users the ability to select the test frequency for more specific measurements. Just like LCR-Reader, Colibri is able to automatically determine the type of component and the best test mode and parameters for the component under test. The main difference between the Colibri and LCR-Reader is the variable test frequencies on the Colibri. When the button on the device is pressed, Colibri will change the measurement mode (AM, L, C, R, ESR) with frequencies of 10 kHz, 1 kHz, or 100Hz available for selection. To reset the device to the default fully-automatic mode, simply hold the button down until the display flashes. The Colibri is available for around $200, making it affordable for non-professionals. This model does not come with the NIST traceable Calibration Certificate. The Smart Tweezers Blog features all the latest news about Smart Tweezers LCR-meter and the LCR-Reader.
