I have spent hours to find right multiplyer etc. but I'm stuck. can someone give an example for a sonar ruler. I'm using telemecanique xx series sonar. But the results are not correct. I try to change the value with analog amlifier. 500 millimeters gives value 645 to analog input I'm using, 110mm gives 992 and 270mm gives 908.
