computer readout vs. test at battery

[mjweber]

1996 Eldorado .The info on the computer ( in car dash) reads a lower voltage than the test on battery . My question is....Is there a way to calibrate the computer to read accuratly?

nada.. but your meter and the car should be close right?? heads up, those caddys eat alternators for lunch, used to change 2-3 a week at the dealer, no joke, look for the rectifier bridge to go out, (or a/c voltage input into the battery/car) very common, which, damages the battery also after prolonged use, have fun...
