Balances with AutoCal
TM
contain software which allows the internal calibration mass to be ad 100
divisions at full scale capacity. This permits calibrating the balance using an external ASTM Class 1 mass which is
traceable to a certified standard.

Enter the number of digits shown between the span calibration value of
the balance and the actual reading. For example, on a 400g balance, the
reading is 400.002g. The difference is 0.002g. This indicates a correction of
2 divisions is required.
