2.4 Adjusting (calibration)
To obtain accurate weighing results, the balance must be adjusted to match the gravitational acceleration at its
location.
Adjusting is necessary
• before the balance is used for the first time
• at regular intervals during weighing service
• after a change of location
Procedure
To obtain accurate results, the balance must be connected to the power supply for 30 minutes (AB-S analytical
balances 60 minutes) in order to reach operating temperature before adjusting.
Analytical balances (AB-S), Precision balances (PB-S certified)
Adjusting with internal weight
➞ To carry out this operation, in the second menu option (Adjustment) select “CAL int” (=factory setting)
(Section 4.1).
➞ Unload weighing pan
➞ Press and hold the «Cal/Menu» key down until “CAL” appears in the display, then release key.
