31.3.2. Determining density of solids
Density of solids is determined by weighing a solid object in two different
medium: in the air and in auxiliary liquid with determined density. The
difference between the two measurements is displacement weight, which
is used by scale software to calculate the density of tested solid.
Before starting the measurement select
<
Local parameters>
menu
and choose
<
Standard liquid>
to be utilized in the density determination
process. Also determine the temperature of the auxiliary liquid. Declaring the
temperature of the auxiliary liquid enables matching its density to a table of
liquid densities. In case of selecting liquid type “Other”, its density value
should be specified in parameter
<
Standard liquid density>
. Here, the
<
Temperature>
parameter is specified only for information purpose of the
report.
Process course:
•
Press
<
Local parameters>
key to enter the setting of local
parameters in density mode.
•
Press
<
Standard liquid>
key to select the auxiliary liquid used
for the density determination procedure. If the auxiliary liquid is other
than “Water” or “Alcohol”, then select “Other” from the available list.
•
Press
<
Temperature>
key and specify the temperature of the
auxiliary liquid [°C]. Accept inserted value by pressing
key.
•
If „Other” liquid has been selected, then press
<
Standard liquid
density>
and insert the density value of the auxiliary liquid expressed
in
[g/cm
3
]
for the specified temperature of the measurement.
•
On specifying the parameters exit to main menu of the density
mode by pressing
key.
•
In order to start density determination of a solid, press
<
Determine solid density>
key, using a pre-defined hot keys on
terminal’s display.
