4 Adjusting the Balance
4-1 Adjusting (Calibrating) the Balance
Calibrating a balance is also called span adjustment. Be sure to perform span adjustment to
ensure highly accurate measurements.
Electronic balances are influenced by the acceleration of gravity. For this reason, you should
adjust (calibrate) your balance every time you relocate it. You should also adjust (calibrate) it
after a long period of use or if it does not indicate correct values.
To perform span adjustment (calibration), wait more than 5 hours after connecting
the AC adapter. Use a weight for adjustment (calibration) that weighs 50% or more
of the weighing capacity. To calibrate the balance more accurately, use a weight
that is equivalent to the weighing capacity.
For calibration of the internal weight, use a weight that has a mass equivalent to the
weighing capacity.
