PURPOSE:To eliminate trouble for adjustment of degree of amplification and signal level by generating parameters corresponding to a connected sensor automatically and then by adjusting the degree of amplification and signal level by the generated parameters. CONSTITUTION:When information for identifying the type of sensor to be connected is input to a parameter-generation part 8, the parameter-generation part 8 outputs an degree-of-amplification parameter 9 and an offset parameter 10. Then, the degree of amplification of an amplifier 4 is adjusted by the degree- of-amplification parameter 9. Further, when an offset-adjusting part 5 feeds offset voltage which is shown by an offset parameter 10 to an A/D conversion part 6, offset at the A/D conversion part 6 is adjusted. Input signal which is input from an input terminal 2 and whose noise, surge, etc., are absorbed by a filter part 3 is converted into digital data by the A/D conversion part 6 and is displayed by a display part 7 where the degree-of-amplification and signal level are adjusted. |
