Abstract
A device for increasing the sensitivity of a testing instrument in determining the presence of an electronic component, such as a miniature ceramic chip capacitor, at the test station before beginning the test procedure, including a signal booster having an input and an output in operable arrangement for boosting an incoming alternating signal from the testing device by a multiple greater than one, connecting the input of the signal booster between the signal output of the testing device and the station for positioning the component for measuring, and connecting the output of the signal booster between an independent direct current power supply and the test station to boost the signal of the presence testing program by a multiple that brings the measurable signal of the component within the range of sensitivity of the testing instrument.
