PURPOSE:To perform a simple and rapid multipoint measurement without monitoring a meter, by a method wherein measuring points are switched in order, and with this the measurement results are outputted in a sound. CONSTITUTION:A control circuit 5 generates timing signal Ta, Tb,... in order and selects measuring terminals 1a, 1b... in turn. A voltage of a measuring point A and the like passes through an AND gate 2a from the terminal 1a, and is applied to a measuring part 3. A value of 35V and the like is measured, and the title of the measuring point A and the measurement value 35V are applied to a sound output control circuit 8 in a sound output unit 6, whereto a start signal is applied from a circuit 5, through an A/D transducer 4 and the circuit 5. A busy signal is then applied to the circuit 5 from the circuit 8, and simultaneously, a ROM7 is caused to access by means of an address corresponding to an input through the circuit 8 to generate a sound output, such as a point A, +35V and the like. Simultaneously, the subsequent terminal 1b is selected through the circuit 5 cancelling a busy signal to be applied, and the measuring point and the measurement value and outputted in a sound in the same manner described above to perform a simple and quick multipoint measurement without monitoring a meter. |
