Adjustment; Models With External Weight (Kern Als/Pls); Adjustment With Recommended Adjustment Weight (Factory Setting) - KERN ALS Series Operating Manual

8 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.
 Observe stable environmental conditions. A warming up time (see chapter 1)
is required for stabilization.
 Ensure that there are no objects on the weighing plate.
