Density determining of liquids
It is determining mass of a plunger if weighed in the air and in tested liquid.
The density of tested liquid is calculated according to a formula:
d
V
B
A
+
−
=
ρ
ρ - density of liquid
A - plunger mass measured in the air
B - plunger mass measured in tested liquid
V - plunger’s volume
d - air density ( max 0,001 g/cm
3
)
Before starting the procedure, assembly the density determination kit, and
insert to balance’s memory volume of the plunger.
−
Press <
Density of liquid > key
−
The display opens a menu, press <
Plunger’s volume> key and insert
the numeric value of volume specified on plunger’s hanger,
−
The balance is ready to start density determining process of liquid.
PROCEDURE
1.
Assembly the density determination kit
2.
Should the density value be saved in a product record of the database of
products, set parameter <Assign density to product> in <Settings> and
activate product using quick access key <Product>,
3.
Press <
START > key,
4.
Follow displayed commands,
5.
Carry out measurement in the air, and on stabilization of measurement
result press <
> key,
6.
Carry out measurement in tested liquid, and on stabilization of
measurement result press <
> key,
7.
The display indicates result of determined liquid density,
8.
Press <
> key to finish the procedure.
Caution:
Pressing <
> key starts another density determining process with the same
settings
