7 Adjustment
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.
• The weight to be used depends on the capacity of the scale. Carry
out adjustment as near as possible to the scale’s maximum weight.
Info about test weights can be found on the Internet at:

• Observe stable environmental conditions. A warming up time (see
chapter 1) is required for stabilization.
