FUNCTIONING
The application provides two ways to use the air buoyancy compensation
procedure.
1. Inserting the specified value of air density and specified value of weighed
sample density to balance’s memory.
On inserting these values the application automatically calculates the
correction factor for weighed mass and indicates corrected value of
weighed mass on balance’s display.
In order to avoid errors, the corrected mass value is accompanied by <
! >
symbol visible on balance’s display and a printout.
2. The application semi-automatically determines the value of air density. The
specified density of the weighed sample is inserted to balance’s memory by
an operator.
Determination of air density is carried out using a set of two mass
standards. One of them is made of stainless steel, and the other of
aluminum. Based on mass indications of the two standards, the software
automatically calculated the air density and saves the value in balance’s
memory on operator’s confirmation. Then the density of weighed sample
has to be inserted to balance’s memory.
On inserting these values the application automatically calculates the
correction factor for weighed mass and indicates corrected value of
weighed mass on balance’s display.
As in case 1, the corrected mass value is accompanied by <
! > symbol
visible on balance’s display and a printout.
Air buoyancy conmpensation mode is enabled / disabled from the level of user
menu. The application is operating in weighing mode only.
STARTUP AND OPERATION OF AIR BUOYANCY COMPENSATION
PROCEDURE
• While in main window press grey coloured workspace
• Select option
• Select parameter < Air buoyancy compensation>
Accessible settings
- Air buoyancy compensation – YES/NO
- Sample density (insert the density value of weighed sample). If an
operator uses products from databases, then on product selection
its density value is automatically uploaded.
- Air density – for selecting the means of inserting the air density
