8.3.1 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 re-
ceive accurate measuring values it is also recommended to adjust the balance peri-
odically in weighing operation.
Using the inbuilt adjusting weight the balance automatically carries out an adjustment
after any temperature change of 3 °C or any time it was disconnected from the power
supply.
Of course it is also possible to check the accuracy of the balance manually any time.
You can choose between two options:
1.
Adjustment is started by pressing the
F
-key three times.
After successful adjustment the balance automatically returns to weighing
mode.
2. Under menu item “
P1 01 Adjustment with internal weight
” (see table below)
Procedure when adjusting:
Observe stable environmental conditions. A warming up time of ca. 1
hour
is re-
quired for stabilization.
Note!
During the adjustment process no objects should be on the weighing plate.
