Siborg Systems Introduces Proprietary Calibration Boards to Extend Tweezer LCR-Meter Measurement Range Below 1 pF/10 nH | PR Newswire [Video]

, /PRNewswire/ — Tweezer-style LCR meters have gained significant popularity in recent years. However, a common limitation among all models is the presence of parasitic inductance and capacitance in the unshielded test leads, restricting the accurate measurement of very small inductances and capacitances. These parasitic effects vary with the distance between the test leads, depending on the component size.

To address this issue, Siborg Systems (Canada) offers proprietary calibration fixtures that effectively compensate for these parasitics, significantly improving measurement accuracy and range.

Since the introduction of the original Smart Tweezers LCR meter in 2005, numerous successors have entered the market. Some of these newer models surpass the original with higher test frequencies, improved accuracy, and additional functionality. Notably, the LCR-Reader line, including the MPA, R2, and R3 models, has expanded the capabilities of tweezer-based multimeters.

Despite these advancements, most tweezer meters share a similar structural design and continue to face the same limitations when measuring extremely small capacitances and inductances due to …
