This adjustmentprocess must be carried out during the initial start-up, after change in location andvariation of surrounding temperature. It is also recommendable to adjust the balanceperiodically during weighing operation in order to obtain exact measured values.This menu item is not available for certified scales without internal calibration weight.Adjusting of non verifiable balancesAdjusting of verifiable balances• Switch off the scale.• Remove the scale bottom plate by undoing the Torx TX20 retaining screws .Impor-tant: In order to remove the bottom plate it is necessary to break the certificationseal affixed to it! Once this seal has been destroyed, the scale must be recertifiedby an accredited organization, and a new certification seal must be affixed beforethe instrument may be used as a certified scale again!• Hold down the service switch (pushbutton) on the analogprint (indicated by anarrow in the drawings below, while at the same time switching on the scale. Keepthe service switch pressed in until "Scale" appears in the display.External For scales without an internal calibration weight:1. Unload scale.2. Activate menu item CAL with .

Place the calibration weight on the scale and confirm with .The scale calibrates with the calibration weight loaded. After calibration is com-pleted, -donE- appears briefly in the display, and the scale automatically returnsto weighing mode.
