20.5. Air Density

< > Air density value is on eof numerous data required for calculation of measurement result
correction, which correction is an effect of air BUOYANCY compensation. Another value required for
the calculation is weighed sample density. The function of air density determination is enabled only in
balances with reading unit lower than d=1mg.
Determining density of air requires use of a dedicated set of mass standards (additional equipment),
specific for a given balance model.
Procedure:
1. Press < Air density> button.
2. Menu of Air Density function is displayed.
3.
4. Press field for entering weight value of steel mass standard, enter the value as provided in
calibration certificate.
