6.5 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 location and variation of surrounding temperature. It is also recommended to adjust thebalance periodically during weighing operation in order to obtain exact measured values.With the built-in calibration weight (refer to the chapter on „Technical data”) it ispossible to check and set the scale accuracy at any time.6.5.1 Procedure when adjustingObserve stable environmental conditions. The warm-up time (refer to the chapter on„Technical data”) is required to ensure the scale stabilisation.To adjust this baby scale when the scale plate is unloaded and the scale is switchedoff, press and hold the ON/OFF key for 5 seconds until the display shows the„CAL0” symbol.Release the ON/OFF key, and the „20.00 kg” display will be shown for a moment.Then place the calibration weight of 20 kg carefully in the centre of the scale plateand the adjustment process will be started automatically.When the adjustment is finished successfully, the display will show the „F” symbolfor a moment and then the scale will be switched off automatically.When an error occurs during the adjusting process e.g. because of incorrect weightvalue, the display will show the „E” symbol for a few seconds and then the scale willbe switched off automatically. As a result of that the scale is not adjusted.6.6 Changing weight unitAt the back of the scale (next to the battery compartment) there is the small slideswitch which you can use to change weight units between kg and lb.When a change is carried out, the display will show the present active weight unit (kgor lb:oz)MBE-BA-e-0911 9
