8 Adjustment
8.1 Adjust balance
As the acceleration value due to gravity is not the same at every location on earth, each
balance must be coordinated - in compliance with the underlying physical weighing
principle - to the existing acceleration due to gravity at its place of location (only if the
balance has not already been adjusted to the location in the factory). This adjustment
process must be carried out for the first commissioning, after each change of location
as well as in case of fluctuating environment temperature. To receive accurate
measuring values it is also recommended to adjust the balance periodically in weighing
operation.
• Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization.
• Carry out adjustment with placed sample dish. Ensure that no objects are within
the sample dish.
• Weight value of the required adjustment weight see chpt. 1 “Technical
specifications“:
 In weighing mode press the CAL button.
 Wait until the weighed value for the required adjustment weight appears
flashing.
Example 100 g
 During the flashing display put the required adjustment weight carefully in the
centre of the sample dish. The flashing display disappears.
After successful adjustment the balance automatically returns to weighing mode.
 Take away adjustment weight
In case of an adjustment error (e.g. objects on the weighing plate) the display will
show an error message, repeat adjustment.
