8.1 P1 Calibration (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.
Procedure when adjusting:
Calibration should be carried out by using a recommended calibration weight.
(See chpt. 1 "Technical specifications"):
Observe stable environmental conditions. A warm-up time of 2 hours is necessary for
stabilisation.
Note!
Sample dishes must be in place. During the adjustment process no objects should be
on the sample plate.
Operation
Call up menu item "P1 Calibration" (see chapt. 7.1)
