testlab2 Posted November 16, 2004 Report Share Posted November 16, 2004 We are having problems with representing Strain outputs on our display. the strain input is a varing voltage which is to represent 5 volts = o strain, 0 volts = -2500 micro-inches Strain , and 10 volts = +2500 Strain. basically we can't seem to get the math formula right which will give us the true neg and pos values in micro-inches. :headbang: Quote Link to comment
