Adjustment - KERN CH 15K20 Notice D'utilisation

7. 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.
Observe stable environmental conditions. A warming up time of approx. 1 minute is
recommended for stabilization.
Prepare adjustment weight, for details see chap. 1 „Technical data".
 Switch on balance
 Press Unit button and hold down (approx. 3 sec) until „CAL" is displayed.
 Wait until the weight value of the required adjustment weight (e.g. 10 kg, see
chap. 1) is displayed.
 Attach adjustment weight, a short time later „F" will appear.
 After adjustment the balance automatically returns to weighing mode.
An adjusting error or incorrect adjusting weight will be indicated by the error
message; repeat adjustment procedure
