The “Differential Weighing” Application
152
When the balance has determined the tare weight, you are prompted to begin weighing.
To perform weighing in, add the weighing sample to the container and then press “OK”.
While the balance is determining the weight, a corresponding message is displayed.
Once weighing in is complete, you are prompted to remove the sample. Remove the
sample vessel containing the sample and confirm with “OK”.
Taring and weighing in of the first sample in the series is now complete. The balance then
automatically starts the above procedure for taring and weighing in all further samples
in the series.
Note: You can terminate all tare and weighing in procedures at any time. All values recorded
up to this point will be saved. If you then press the “T & wgh. in” function key again, the
balance automatically calls the first sample for which there is no tare or weigh-in value.
After the last sample, a message is displayed confirming that taring and weighing is
complete for all samples in the series.
Confirm the message with “OK”. The balance is then ready to perform residual weigh-
ing.
Before residual weighing, you separate components from, or add new components to the
samples. This includes procedures such as drying, centrifugation, filtering, inc ineration,
vaporization, coating, etc..
Residual weighing of samples
Press the “Residual wgh.” function key.
Since you can re-weigh every sample up to 3 times (e.g. for samples in which components
are added or separated in several steps), a window is displayed in which you which residual
weighing procedure is being performed. In this example, no residual weighing has yet
been performed. Only the first residual weighing is therefore offered for selection.
To start residual weighing, press the button for the required residual weighing proce-
dure.
