31. WORKING MODES – DENSITY
Working mode <
Density>
enables determining density of solids, liquids
and materials of high viscosity. The density is determined on basis of
Archimedes principle, according to which any floating object displaces its
own weight of fluid. The density mode also enables utilizing a pycnometer
for determining density of liquids.
31.1. Starting the working mode
Procedure:
• While in main window of the software, press on-screen key, located
in the upper bar of the window, which opens submenu Modes>
containing list of available working modes,
• Select working mode <
Density>
, the software automatically returns
to displaying the main window, and the upper bar indicates the icon of
selected working mode,
• Simultaneously, the workspace of the display indicates a message:
.
31.2. Local setting of a working mode
Local settings for the working mode <
Density>
are accessible
on pressing a hot key < Local parameters>:
Standard liquid
Function dedicated for determining the standard liquid.
There are three options: water, alcohol and other. If option
“other” is selected, then its density should be specified. In
case of the other two types of liquids, their ensity values
are implemented in the software
Temperature
Parameter of the standard liquid inserted by the scale
user. Declared temperature of the standard liquid
automatically determines its density based on a table of
liquid densities. In case of the liquid type “Other”, the
temperature parameter is not applicable, the density value
is inserted manually
Standard liquid
density
Parameter designed for manual determining the density
of standard liquid in [g/cm 3 ]
Sinker volume
Parameter implemented for manual determining the
volume of a sinker expressed [cm 3 ]
