5.6 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 during the initial start-up, after change in
location and variation of surrounding temperature. It is also recommendable to adjust
the balance periodically during weighing operation in order to obtain exact measured
values.
Using a precision weight, the accuracy of the balance can be checked at any time
and adjusted.
Adjustment procedure:
Check that the surrounding conditions are stable.
A short warm-up time of about 3 minutes is recommended for stabilisation.
• Use the
key to switch the balance on.
• Press the
key and hold depressed for approx. 10 seconds until “CAL“
appears on the display.
• Release the
key; the size of the calibration weight is shown on the display
(see chapter 1, Technical Data).
• Now place the calibration weight in the centre of the weighing plate.
• “F“ will appear for a brief period of time before the balance switches off / then
the automatic return to the weighing mode depending on model).
• Remove the calibration weight. Calibration is completed.
In case of an adjusting error or a wrong adjusting weight “E“ will appear. Repeat the
adjusting procedure.
Keep the adjusting weight near the balance. Daily verification of the balance accura-
cy is recommended for quality assured applications.
