8.5 Function to
“
Fix the density
”
The density function allows to determine the density value of solid or liquid substances. The
determination is based on the principle of Archimedes that a body immersed in a liquid
receives an upward thrust equal to the weight of the volume of the displaced fluid. For the
determination, you can use the lower weighing device (if present in the scale or the
"hydrostatic weighing kit" to place on the weighing plate (optional).
To access the function from the "Functions" menu, tap the "
Density
" icon.
Select the mode:
Liquid density:
selecting this type of
measure, you will be required to enter the
solid density value (g/cm3) to be used to
determine the density of the liquid.
Then tap the "
Start
" button to proceed with
the measurement
Solid density:
selecting this type of
measure, you will be required to enter the
solid density value (g/cm3). If using distilled
water or ethanol, select the relevant item
below and enter only the liquid temperature
value. The density of the selected liquid at
the temperature entered will automatically
be entered. (The reference tables are
stored inside the device).
Then tap the "
Start
" button to proceed with
the measurement
Density index:
by selecting this type of
measurement, you can determine the
difference in density as a percentage
between two solid samples. (One solidified
at room temperature and the other under
vacuum).
The density index can be determined by
measuring for both samples their density
value, or by using the "
theoretical density
"
value for the sample solidified at room
temperature and measuring the density
value only for the vacuum sample. In this
case, you need to tap the "
Theoretical
density
" key to enter the value.
Then tap the "
Start
" button to proceed with
the measurement
