We produced by way of experiment the autmatic electricity quantity-recording meter which converted the quantity of electricity (voltage, current,power etc.) into the proportionate direct current output by the transducers and recorded it in the portable recorder.
　This report described the principle and organization of the measuring apparatus.
　Finally, we tested the instrument for development and compared the measured value of the standard meter with the recorded value of the measuring apparatus.
　Consequently, we made sure of that this measuring apparatus was practicable enough.
