    摘要： An apparatus and method for determining the number of turns on a sample coil are disclosed. An alternating current of substantially constant amplitude is passed through a primary winding turn which is coupled to the sample coil and also through a primary winding turn which is coupled to a standard coil of known turns count, inducing currents in the sample coil and in the standard coil in inverse proportion to their respective turns counts. These induced currents are commutated into pulsating direct currents that are fed into a ratiometric current meter. This meter produces a measurement output corresponding to the ratio of the current induced in the standard coil to the current induced in the sample coil. This measurement output is displayed on a calibrated readout device as an indication of the number of turns on the sample coil. In addition, means are provided for indicating coil discontinuity and inverted coil phase.

    摘要： This disclosure relates to a simple apparatus for and method of testing and blocking electrical coils made from an elongated strip of electrically conductive material which utilizes a radially expandable mandrel to hold a coil in position so that one or more leads thereof may be easily connected in an associated electrical circuit using rapidly operating electrical connectors comprising the apparatus, and with a given coil thus held it is rapidly tested and if found acceptable the coil is immediately blocked prior to removal thereof from such mandrel.
