I am attempting to read weight data from a loadcell in a labview VI. I took a look at the example code posted here; (Link) and noticed that the author multiplied the signal by 5000000. Im wondering what the rhyme or reason is to choosing that amplification value, if there was any at all. Thanks.

Load cells come with a "chart" or formula that relates their output to their specified load, ie: 1mV/1 Kg. Some are relatively linear across their normal range so a simple formula can be used. It appears that the input is configured for a fullscale input of around a millivolt, so X500000 would translate this to 500 of whatever units the fullscale is refered to (pounds, kilograms, whatever)
