"Your result will be *much* more accurate if you accumulate the raw numbers and display the total divided by 3600. (BTW, what do you use MASSBUFF for?) "

Yes you are right. It defenitley will be more accurate that way. And once I start doing this, then the use of MASSBUFF register is not warranted. The only downside in this case, is the size of the MASSVAL register - it has to be 32bit wide to store the maximum possible value(3,599,996,400) for a display of 999,999 kg. But this is not a problem.
