<p>PURPOSE:To enable zero-point and span-value adjustment to be made easily by setting signal obtained from a potentiometer to a measurement data and by performing calculation using the zero-point data and span-value data which are obtained by a signal-reading means. CONSTITUTION:A slider of a potentiometer 1 is set to a position of 0% before adjusting span and zero point and a zero adjusting command is sent from a communication means 2. By receiving this command, a first signal-reading means 3 reads a resistance signal which is obtained between the slider and one edge on the potentiometer 1. Then, the slider of the potentiometer is set to 100% position and a span value adjusting command is transmitted from the communication means 2. By receiving this command, a second signal-reading means 4 reads resistance signal at that time. A calculation means 4 performs a specified calculation using these two resistance signals for obtaining output signal and then performs zero-point and span-value adjustment easily.</p> |
