6.6 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.
6.7 Adjustment
The adjustment should be made with the recommended adjustment weight (see
chap. 1 "Technical data"). Adjustment is also possible with the weights of other
nominal values, but not the optimum for measuring technique.
Procedure when adjusting:
Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization.
Operation Display
 Start balance by pressing
The balance displays for approx. 3 seconds [88888]
and then goes to [0]. Now it is ready for operation.
 Press
and keep it pressed, [CAL] is displayed
After approx. 5 seconds appears the size of the
recommended adjustment weight
(Example)
 Place adjusting weight in the center of the weighing
plate, short time later appears [F]
Afterwards the balance automatically jumps back to
normal weighing mode. In the display there appears the
value of the adjustment weight.
(Example)
An error during adjustment or the use of an incorrect adjusting weight will result in an
error message „CAL E“. Repeat adjustment.
Keep the adjustment close to the balance. Daily control of the weighing exactness is
recommended for quality-relevant applications.
