31.3. 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.

31.3.1. 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.
