PURPOSE:To enable continuous measurement with good accuracy by combining organically a large range measurement device and a small range measurement device. CONSTITUTION:The output signal E5 (E5=0.333E4) of the inclination equal to the inclination of the measurement signal E1 of a large range measurement device 1 is transmitted from a coefft. multiplier 4. On the other hand, the voltage 3.33V corresponding to a range change-over point is transmitted as a set signal E8 from a signal generator 8. A high selector 7 compares the signal E1 of the device 1 and the set signal E8, and transmits the signal E1 as a selection signal E8 when the signal E1 is larger than 3.33V and transmits the signal E8 as a selection signal E9 when the signal E1 is smaller than 3.33V. A low selector 5 compares the output signal E5 of a multiplier 4 and the signal E8 and transmits the signal E5 as a selection signal E10 when the signal E5 is smaller than 3.33V and transmits the signal E8 as the selection signal E10 when the signal E5 is larger than 3.33V. |
