MULTIPOINT MEASURING INSTRUMENT

PURPOSE:To eliminate the power loss of sensors and to commonly use an amplifying means and A/D-converting means for the sensors by changing the amplification factor of measure outputs in accordance with the kind of the sensors so as to control the amplified outputs to the same degree of levels. CONSTITUTION:A CPU 23 successively selects sensors 7 by reading out the setting information of all channels of each measurement board 36-38 from a memory 24. Namely, the CPU 23 first sets the 1st measurement board 36 to an operating state by sending a channel and power supply selecting signals to the 1st measurement board 36. When the board 36 is set to the operating state, the board 36 returns a kind-of-board signal to the CPU 23. The CPU 23 successively performs similar measuring operations to the 2nd and 3rd boards 37 and 38 for all channels. Since the CPU 23 is constituted in such a way that the CPU 23 successively transfers corrected measured values to a host CPU 9 after reading-out the values from the memory 24 and obtains measured values in time-divided state in accordance with selected sensors, the power loss of the sensors can be reduced.
