3.10 Differential Weighing (Cont.)
Procedure (Cont.)
First, the container is tared and stored, then the product is
intially weighed in the container and stored for each sample.
A name is given to the samples which is stored in the balance.
After all samples have been weighed and entered, a summary
table indicates the weight of the containers and each sample.
After the samples have undergone a process such as heating
or cooling, the entire procedure is repeated starting with sample
number 1 and continued until all samples have been completed.
The balance then displays a new table which indicates the tare
weight of the container, the initial weight of the product, the
final weight of the product and the difference weight. To enter
samples, proceed as follows:
Initial Weighing
• Press # button.
• Place container on pan, wait for stable indication, then
press Enter button. The display indicates the container
weight.
• Place the first sample in the container on the pan. The
display indicates the initial weight of the first sample.
• Press Enter button, display changes to sample 2.
• Remove first sample and container from pan.
• Place container on pan for sample two, press Enter button.
The display indicates the container weight.
• Place the second sample in the container on the pan. The
display indicates the initial weight of the second sample.
• Press Enter button, display changes to sample 3.
• Remove second sample and container from pan.
• Repeat the above procedure for all samples. The example
shown at left is for one sample.
When the last sample is placed on the balance, a summary
display indicates the TARE WT and INITIAL WT.
• Using the arrow buttons, select CONTINUE or SAVE, then
enter Data File Name.
Final Weighing
When all of the samples have been removed and processed
externally, reenter Differential Weighing and select RESUME.
The final samples are weighed with their containers one after
another. When the last sample is weighed on the balance, a
final summary display is shown. See example at bottom of the
page. The final summary indicates the TARE WT, INIT WT, FINAL
WT and DIFF (difference weight). This can be printed. The RE-
SAMPLE and EDIT selections on the displays allow corrections
to be made.
