5.6 AdjustmentAs 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 physicalweighing 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). Thisadjustment process must be carried out during the initial start-up, after change in lo-cation and variation of surrounding temperature. It is also recommendable to adjustthe balance periodically during weighing operation in order to obtain exact measuredvalues.5.6.1 AdjustingUsing a precision weight, the accuracy of the balance can be checked at any timeand 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“ ap-pears 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.• Remove the calibration weight. Calibration is completed.In case of an adjusting error or a wrong adjusting weight “E“ will appear. Repeat theadjusting procedure.Keep the adjusting weight near the balance. Daily verification of the balance accu-racy is recommended for quality assured applications.EMB-BA-e-113210
