Siborg Finalizes Universal Calibration Jig

// July 31st, 2015 // No Comments » // LCR-Reader, News

With help from the Institute of Automation and Electrometry at the Russian Academy of Sciences in Novosibirsk, Siborg Systems Inc. has created a universal jig that can calibrate all models of Smart Tweezers and LCR-Reader LCR-meters. Siborg has sent the jig to Navair Technologies in Toronto, one of the leading calibration houses in Canada. Navair will be able to grant the jig its own NIST Traceable Calibration Certificate.

The jig itself cannot create a calibration certificate, but is helpful for periodic calibration, or to troubleshoot devices that have malfunctioned or failed.

The jig utilizes a set of 14 known components of different types and within the Smart Tweezers measurement ranges. A previous version of the jig used a 4-wire Kelvin probe to connect to the LCR-meters; this has been changed to use a 2-wire connections. The 2-wire connection means that the jig can calibrate all models of Smart Tweezers ever made. ¬†When the jig is connected to a device, it will cycle through the components; the measurement results are displayed on the Smart Tweezers’ display which can then be compared to the known values of the jig.

“We have also decided to create two versions of the Jig for both 4-wire and 2-wire terminals. The jig is helpful in that it can be used for periodical traceable calibration if the jig itself is calibrated. The 4-wire jig is best for models after Smart Tweezers ST-3, including the LCR-Reader. The 2-wire jig is used for models before and including the ST-3.” says the Director at Siborg, Michael Obrecht.

The 4-wire Kelvin probe that was initially used minimizes noise generated by the connections on the PCB, but does not cater to older models. The 2-wire jig is best suited for the Smart Tweezers ST-1, ST-2 and ST-3 where the 4-wire connection wasn’t used in the handles.

Along with the jig, Siborg sent 4 randomly selected LCR-Readers to Navair. The results that were sent back were better than expected; the LCR-Reader was thought to have a 1% basic accuracy, where as the measurement results showed closer to 0.5%.

Siborg Gets Results from Navair about Calibration Jig

Siborg Systems Inc., with help from the Institute of Automation and Electrometry at the Russian Academy of Sciences (Novosibirsk) have created a Calibration Jig for the Smart Tweezers and LCR-Reader models. This jig was sent to Navair in Toronto, Ontario, one of the leading calibration houses in Canada. The results have made their way back to Siborg with surprising results.

4 Randomly selected LCR-Reader units were sent for testing and calibration. Siborg had been claiming that the LCR-Reader had a basic accuracy of about 1%, which turned out to be underestimated; almost all the measurement values were closer to 0.5%. The only measurement to be out of the estimated range was the 1 Ohm, which was slightly higher because of parasitics between the tips. All the measurement results can be seen on the LCR-Readers’s website.

The Calibration Jig does not in itself create NIST traceable certificate, and must have a certificate itself; but this device will allow users to sporadically check the accuracy of their devices or to troubleshoot in cases of failure or malfunctions.

Siborg Systems Inc. has paired with Shanghai Cuiyan Electronic Instrument Co., LTD. to resell Smart Tweezers and LCR-Reader in China and surrounding areas.

Shanghai Cuiyan Electronic Instrument Co. LTD. is a premium reseller for all types of products for the electronics industry.

“We are excited to have Shanghai Cuiyan Electronic Instrumen Co. LTD. as a reseller for Smart Tweezers and LCR-Reader. We believe that it will be a good fit among their other products and their customers will appreciate the Smart Tweezers line of LCR-meters. This deal also offers a closer-to-home option for customers who need their device repaired or maintained.” says Michael Obrecht, the Director at Siborg Systems Inc. in Canada.
