hi does any one know if this tachometer circuit can be calibrated so that it only starts working at 7750 rpm for example: i want it so that at 7000 rpm to be 0 volt output, 7750 rpm to be 1 volt, 8000 rpm to be 2 volts, 8250 rpm to be 3 volts, 8500 rpm to be 4 volts, 8750 rpm to be 5 volts and 9000 rpm to be 6 volts any ideas would be appreciated?
