the program automatically calculates the air density and saves the value in balance memory on
operator's confirmation. Now, enter value of weighed sample density to balance 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 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.
Settings:
•
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 you to select 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 (to complete air density determination press
< > key).
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 and internal), then data from the THB
supersedes the other, in such case go to Setup/Ambient conditions/Ambient conditions module
parameter and set SAVE or SAVE & ALERTS value.
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 parameter and set NONE value,
•
external THB sensor exclusively – go to Setup/Ambient Conditions/Ambient conditions
module parameter and set SAVE or SAVE & ALERTS value.
For correct balance cooperation with the THB sensor it is necessary to set port's transmission
parameters, they must be compatible with those of the THB sensor. The THB sensor transmission
parameters are detailed on its data plate.
On returning to the weighing mode, the display indicates an additional symbol
the figure below. From now on the value of indicated mass is corrected, wherein the air buoyancy
compensation factor and sample density are referred to.
The measurement result can only be compensated by a correct value if the operator enters the actual
value of the air density and correct value of weighed sample density to balance memory.
Caution! If the <AIR BUOYANCY COMPENSATION> parameter is set to <ONLINE> value, then <!>
pictogram is not displayed. This means that Setup/Ambient Conditions/Ambient conditions module
parameter is set to SAVE or SAVE & ALERTS value, and that there is either no physical balance-module
connection, or that balance-module communication parameters are incorrect. In such case plug the
