negative numbers

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.

In the units you specified, I think that the equation would be:

Strain = (500 * Voltage) - 2500

Strain = (500 * Voltage) - 2500

Thanks for your help. We were stumped.
