PURPOSE:To adjust the output signal of a reference signal generating means without using any external measuring instrument and to reduce the manpower of the connection of a measuring instrument by varying the signal outputted by the reference signal generating means on the basis of the display of a segment display means. CONSTITUTION:Analog signals outputted by a sensor 21 and the reference signal generating means VR are compared with each other, the comparison signal is inputted to the segment display means 7 through an A/D converter 32 and a decoder 32, and the output signal of the reference signal generating means VR is varied on the basis of the display of the segment display means 7. Consequently, the output signal of the reference signal generating means VR is adjustable without using any external measuring instrument. |
