A. H. Wolferz

In connection with the installation, operation, and repair of amplifier equipment as used in the motion picture industry, various electrical measurements are necessary. In order to carry out these measurements, a portable test set was designed. This test set was arranged to measure the various voltages and currents encountered in amplifying equipment and in addition, means were provided for testing circuits, amplifier and rectifier tubes, and for measuring resistance and capacitance.
