Abstract

A measuring device provided with a memory unit for storing correction data, wherein the memory unit is controlled by a control circuit; the correction data is transmitted to a main memory through an input-output device; a transducer measures living body data, and converts the measured data into an electric signal; a digital signal converted from the electric signal by an analog-digital converter is delivered to a central processing unit as measured data; the transducer, memory unit and control circuit jointly constitute a measurement-correcting module, which is detachably attached to the input-output device; the central processing unit corrects the measured data by the correction data stored in the main memory, and converts the corrected measured data into a display signal; and a display device indicates the measured data in accordance with the display signal received.

Claims2

Dependent claims

A measuring apparatus comprising:

a. measuring means including a plurality of transducers for measuring a plurality of different data and converting the measured data into analog electrical signals;
b. analog-digital converting means connected to the measuring means to convert analog electric signals from the measuring means into digital signals;
c. correction means connected to the analog-digital converting means for storing a plurality of different correction data for the plurality of measured data, for correcting each of the measured data using the corresponding correction data, and for further correcting a first of the corrected measured data using a second of the corrected measured data, said first corrected measured data being a function of at least two variable factors and said second corrected measured data being a function of at least one variable factor and being one of said at least two variable factors of said first corrected measured data;
and
d. display means connected to the correcting means for displaying corrected measured data.
