The specific liquidweight is calculated on the basis of those both values.The display unit for the specific liquid weight is „d”.Density determination becomes even easier when an optional set for densitydetermination is applied. For further information please refer to the operatinginstructions enclosed with the set for density determination.Select the menu element 61 in the menu overview.• Enter the sinker density value.• Remove the cover of the hook for underfloor weighing in the balance bottom.• Attach the sinker on the hook and immerse it in the container filled with theliquid to be tested.• Restore the weighing mode with the ESCON/OFFbutton and press UNITbuttonrepeatedly until the „d” symbol is displayed.• Place the sinker on the balance plate.• When the stabilisation display is illuminated, press MENUCALbutton.
