20.5. Density of air
Density of air < > is a piece of information required to calculate correction
of measurement result related to air BUOYANCY compensation. Another data
required in this process is the density of weighed sample. The function of air
density determining is enabled only in balances with reading unit lower than
d=1mg.
Determining density of air requires using a dedicated set of mass standards
(additional equipment), specific for a balance model.
PROCEDURE:
1. Press < Air density > quick access key,
2. The display indicates options related to this mode
3. Press field with mass of steel standard and insert its value as provided in
its calibration certificate,
4. Press field with mass of aluminium standard and insert its value as
provided in its calibration certificate,
5. Press field with density of steel mass standard and insert the density
value,
6. Repeat process for the aluminium mass standard,
7. Press START field – is ready to start density determining process of the
air.
8. Load steel mass standard on balance’s weighing pan and on stabilization
of measurement result accept it by pressing < > key,
