considerably the final result, wherein the density is influenced by changes of pressure,
temperature and humidity.
In order to carry out a reliable measurement it is necessary to know the measuring methods, features
of tested sample, air density in the laboratory room and density of weighed sample.
Functioning
The air buoyancy compensation procedure is to be used as follows:
1. Method 1:
Enter air density value and value of weighed sample density to balance’s memory. Wait, the
software automatically calculates the correction factor for weighed mass, next corrected value
of weighed mass is displayed. In order to avoid mistakes, the corrected mass value is
accompanied by <!> symbol, the symbol is visible on a display and a printout.
2. Method 2:
Determine air density value with use of balance software (semi-automatic operation) and enter
value of weighed sample density to balance’s memory.
Determination of air density is carried out using a set of two mass standards, one made of
stainless steel, and the other one of aluminum. Based on mass indications of the two
standards, the software automatically calculates the air density and saves the value in
balance’s memory on operator’s confirmation. Now, enter value of weighed sample density to
balance’s memory. Wait, the software automatically calculates the correction factor for weighed
mass, next corrected value of weighed mass is displayed. The corrected mass value is
accompanied by <!> symbol, the symbol is visible on a display and a printout.
In order to enable/disable the air buoyancy compensation procedure go to the user menu. The
procedure is valid for weighing mode exclusively.
Air Buoyancy Compensation Start-Up
Procedure:
1. Enter home screen and press grey workspace.
2. Select <Settings> parameter.
3. Select <
Air buoyancy compensation> parameter.
Parameter values:
•
Air buoyancy compensation – YES/NO.
•
Sample density (enter value of weighed sample density). If you use products from
databases, then on product selection its density value is automatically uploaded.
•
Air density – parameter designed to enable selecting the method of entering the air
density value.
PARAMETER VALUES:
VALUE – select to open a window where you enter specified air density value (e.g.: determined by
means of other methods). The entered value is used in the course of compensation. It is assigned
automatically upon completed air density determination after < > key has been pressed.
ONLINE – select to make the balance acquire air density value from a connected THB sensor at a
real time, if such is connected to the balance, or from internal sensor installed in the balance.
If your balance features both types of sensors (THB module and internal sensor), then data from the
THB module supersedes the other, in such case go to
Setup/Ambient Conditions/Ambient
Conditions Module and set SAVE or SAVE & ALERTS parameter.
If your balance features only one set of sensors recording temperature, humidity and pressure, then
correct ONLINE operation requires setting the following parameters:
•
internal sensors exclusively – go to Setup/Ambient Conditions/Ambient Conditions Module
and set NONE value,
•
external THB module exclusively – go to Setup/Ambient Conditions/Ambient Conditions
Module and set SAVE or SAVE & ALERTS value.
