14. Density Measurement
The balance is equipped with a density mode. It calculates the density of a solid using the
mass value of a sample in air and the mass value in liquid.
Note
The density mode was not selected for use when the balance was shipped from the factory.
To use the mode, change the function table and activate the density mode.
When the density mode is selected, the response adjustment function can not be used.
Minimum display is 0.0001 g while density mode.
Formula to obtain the density
The density can be obtained by the following formula.
Where
ρ : Density of a sample
A : Mass value of a sample in air
B : Mass value of a sample in liquid
ρ
0
: Density of a liquid
Prior to measurement: Changing the function table
Prior to measurement, change the function table as follows:
1 Selecting the density mode.
The density mode is available as one of the weighing units.
Select it by pressing the
MODE
key. To use the mode, select it (unit of
Unit d
.) in the
function table. Refer to "5.2. Changing Units".
2 Selecting a way to set the density of a liquid.
Select the liquid density input method from the function table below.
Note
The function table is available only when the density mode (
d5fnc
) is selected.
