New Verification Tool for Smart Tweezers and LCR-Reader

Siborg Systems Inc. and the Institute of Automation and Electrometry of the Russian Academy of Sciences in Novosibirsk, Russia have joined to develop a new verification tool for the Smart Tweezers line of LCR-meters.

The jig uses 16 known components, including 8 resistors, 4 capacitors and 4 inductors of different values within the Smart Tweezers and LCR-Reader measurement range. The LCR-meter is connected to the verification jig using a 4-wire connection. When connected, the jig connects to each component and displays the results on the Smart Tweezers’ display. The tester than compares the component value to the resulting test values on Smart Tweezers.

The 4-wire connection used ensures that there is less noise being generated by the connections on the PCB. Each connection is then controlled by a microprocessor and  a set of 32 relays. After a switch, the micro-controller goes into sleep mode which further reduces the effect of the digital circuitry on the measurement.

“Although all Smart Tweezers PCBs are calibrated after the PCB is made, the verification jig is still a desirable tool for incoming control and troubleshooting devices returned due to a failure or malfunction. It can also be used for periodical traceable calibration if the jig is calibrated by a certified agency. The best thing about the jig is that it can be used for any model of Smart Tweezers after the ST-3 where, for the first time, the 4-wire connection was utilized.” says Michael Obrecht, the Director of R&D at Siborg Systems Inc.
