ログ出力装置付き計測器。 The measurement signal from the measurement unit is digitally processed in the arithmetic control unit, the processing result is D/A converted by the analog output circuit, and the converted analog output can be outputted via the analog output jack. In a measuring instrument with an analog output device, the A contact of the front analog output jack is connected to the output side of the analog output circuit, while the B contact is connected to one input terminal of the comparator, and the B contact is connected to one input terminal of the comparator. A voltage of a predetermined magnitude is inputted, and a comparison voltage smaller than the voltage and larger than the highest value of the analog output output from the analog output circuit is applied to the other input terminal of the comparator. Further, the output side of the comparator is connected to the calculation control unit, and the calculation control unit automatically turns off the power only when a predetermined output from the comparator is input to the calculation processing unit. A measuring instrument with an analog output device, characterized in that the function is released.
