Claims

[Scope of utility model registration request]

An A/D converter 2 that converts an analog signal from the detection unit 1 according to the measured quantity into a digital signal and outputs a conversion end signal, and an A/D converter 2 for instructing the A/D converter to start A/D conversion. a control unit 3 that supplies a conversion start signal, inputs a conversion end signal from the A/D converter 2, and outputs a data read signal;
A measuring device comprising a processing section 4' which receives a data reading signal from the control section 3, inputs a digital signal from the A/D converter 2, performs arithmetic processing, and outputs the arithmetic processing result as a measurement signal. , when the A/D conversion start signal is supplied from the control section 3 and the A/D conversion end signal is not supplied from the A/D converter 2, the measurement signal output from the processing section 4' is transmitted to the device. A measuring device characterized in that it is provided with a failure detection section 6 that switches to a signal indicating the worst state of the measured quantity.
