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.
