Adjustment - KERN EOA Series Operating Manual

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"). Weights of different nominal values may be used for
adjustment but are not optimal for technical measuring.
Procedure when adjusting:
Observe stable environmental conditions. A warming up time (see chapter 1) is
required for stabilization.
Operation
 Start balance by pressing
 Await zero display
 Press
and keep it pressed, [CAL] is
displayed
 After approx.5 seconds appears automatically the size
of the recommended adjustment weight
 Place adjustment weight in the middle of the weighing
plate, short time later [F] will appear.
Afterwards the balance automatically jumps back to
weighing mode. In the display there appears the value of
the adjustment weight.
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.
