The XTR110 disorder and span adjusting circuit

Published:2011/6/22 2:37:00 Author:Borg | Keyword: disorder, span adjusting | From:SeekIC

In the figure is the malfunction and span adjusting circuit of 0~10v input voltage and 4～20mA output current. R1 is the disorder adjusting potentiometer, R2 is the span adjusting potentiometer. Disorder adjusting method: input a low voltage that is not 0, adjust R1 and make the output have a right current value, and then make the input be 0, so that the output must be 0. Span adjusting method: the set input voltage as full scale +10v, adjust R2 to make the current reach to top limit of 20mA. What need to be noticed is that the span adjustment will affect the disorder adjustment.
