18.13.4. Density of air
Density of air is one of parameters required for calculating a correction value
for a measuring result related to air BUOYANCY. Another parameter needed
to calculate the correction value is density of tested sample.
1. The procedure requires a set of
two standards: an aluminum one
and a stainless steel one, both
with determined mass. The set of
weights is additional equipment
of a balance 3Y series.
PROCEDURE:
o press Quick access key: AIR
o to open a screen on density
determining of air
o press field with the value of the
stainless steel standard and
enter its value
o press field with the value of the
aluminum standard and enter its
value
o if the mass standards in use are made of other materials, then change
the value of fields related to density of the material
o press START field - the balance is ready to determine density of air
o follow the commands displayed in the COMMAND BAR of the
workspace area.
− Place stainless steel standard on balance weighing pan
− After stabilizing of the indication press OK button
− Place aluminum standard on balance weighing pan
− After stabilizing of the indication press OK button
− Balance display shows calculated result of air density.
