This PCB emulator allows Smart Tweezers and Colibri LCR-meter users to easily and accurately find the offset capacitance to a varied range of components (02014, 0402, etc.) with a simple measurement. The PCB uses holes at the width of components; when the tips of a device are inserted in the holes, the device will give the actual offset value. This value can then be subtracted from the value of the component being measured.
Previously, to find out the parasitic value, users had to approximate the width of the component with the tips. This method was unreliable for accuracy.
The Offset Calibration Board also makes setting the Smart Tweezers’ semi-automatic offset subtraction value easier.
