Navair Technologies' Results for LCR-Reader Calibration

Navair Technologies Inc. is one of the leading calibration houses in Canada.

Siborg Systems Inc. sent 4 randomly selected LCR-Readers along with the new calibration fixture to Navair Technologies. The results sent back for the LCR-Readers were better than expected; previously it was thought that the device had a 1% basic accuracy, but the results placed the accuracy closer to 0.5%.
The new calibration fixture was sent to be tested for accuracy and certification itself. If the fixture is certified, the LCR-Reader may be able to have calibration certificates themselves, which is one of the main reasons that companies are hesitant to use them.

The Calibration Fixture

The new calibration fixture was created with help from the Institute of Automation and Electrometry at the Russian Academy of Sciences in Novosibirsk, Russia.
The new fixture was designed for testing all models of Smart Tweezers; it utilizes a 2-wire Kelvin connection, unlike an older design of the fixture that used a 4-wire connection. The 4-wire had been proven to eliminate noise between the components and the PCB, but did not allow testing for Smart Tweezers models ST-3 and older.
The fixture utilizes 14 known components. When a ST or LCR-Reader is connected, the fixture will cycle through the components with the measurement results displaying on the ST or LCR-Reader display. These results can then be compared to the known values and the device can be calibrated accordingly.
