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 <Settings>

• 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

value used for calculating buoyancy correction factor.

Settings:

VALUE – selecting this option opens a window for inserting

determined value of air density (e.g.: determined using other

methods). The inserted value is used to calculating buoyancy

compensation factor. The value is assigned automatically on

carrying out the air density determination (on its completion by

pressing < > key).
