<P>PROBLEM TO BE SOLVED: To provide a multipoint switching type measuring apparatus that can measure all channels by shortening the updating cycle of measuring of a specific channel and extending the updating cycles of measuring of other channels. <P>SOLUTION: A multipoint switching type measuring apparatus which sequentially switches, with a multiplexer, analog input signals to a plurality of channels and an internal calibration signal and inputs the switched signals digital-converted with an AD converter to a digital processor. The digital processor comprises a sequential operating means which provides the multiplexer with operation signals for sequentially switching, out of the input signals of the plurality of channels, a combination of channels that require fast updating and other channels or the internal calibration signal, and inputting the switched signals to the AD converter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
