20.4. Determining density 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 in and
activate product using quick access key ,
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
