differentiated.
From now on the balance continues weighing in the II weighing range.
In order to return to weighing with the accuracy of the

10.7. Use of air buoyancy compensation factor

The application enables correcting mass measurement errors during:
1. Weighing loads that density considerably differs from the density of
standard used to adjusting the balance. Regularly, the balance is adjusted
with a steel mass standard with density ~8.0g/cm
standard with density ~8.7g/cm
