28.3. Carrying out density determination procedure
Working mode < Density> enables determining density in 4 different
methods, depending on material which density should be measured.
Methods of density determination:
• Liquid
• Solids
• Pycnometer
• Porous material
28.3.1. Determining density of liquids
Density of liquid is determined by measuring mass of a sinker with
determined volume. First, the sinker has to be weighed in the air, and then
in liquid of which the density should be measured.
The difference between the two measurements is displacement weight,
which is used by scale software to calculate the density of tested liquid.
Before starting the measurement, the sinker’s volume should be inserted
to scale’s memory. The sinker’s volume is given on its hook.
Process course:
• Press < Local parameters> key to enter the setting of local
parameters in density mode.
• Press <
Sinker volume> in order to insert the volume of the
sinker (given in [cm
3
]) which is immersed in the tested liquid.
• On specifying the parameters exit to main menu of the density
mode by pressing
key and saving inserted changes.
• In order to start density determination of liquid, press <
Determine liquid density> key, using a pre-defined hot keys
on terminal’s display.
Caution:
If in the local parameters, <
Ask about sample number> function
is enabled, then on initiating the process, the system asks for inserting
the number of tested sample. The inserted sample number is linked to
the process data and saved in the database.
