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 <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
