12 The “Differential Weighing” Application
This section describes the “Differential Weighing” application. Here you will find information on how to work with this application and
on the relevant setting options.
Please note that all settings for the “Differential Weighing” application are stored under the active user profile. This means that you can
enter user-specific settings for this application. You must therefore ensure that you have first selected the desired user profile.
Important: Specific data related to differential weighing (definitions and names of series and samples, etc.) and weighing results are
stored in a database. The database is independent of the user profile. There is only one database available for all users.
12.1 Introduction to the “Differential Weighing” Application
The Differential Weighing application is used to analyze changes in the weight of one or more samples. The first step is to determine
the initial weight of the sample (weighing in). Selected components are then separated from or added to the sample. This includes
procedures such as drying, centrifugation, filtering, inc ineration, vaporization, coating, etc. After the sample has been processed, it is
re-weighed (residual weight). The balance then determines the difference between the two weighed values.
You can define up to 99 series, each of which can contain multiple samples (the balance can manage a maximum total of 500 samples).
Each sample can be tared, weighed in, and re-weighed up to 3 times.
For each series, you can also define whether the operating sequence is performed automatically or manually. In automatic processing,
the balance guides you through each step of differential weighing for every sample (taring, weighing in, residual weighing). In manual
processing, you can specify the order in which you want to process the samples. In both types of processing, the balance stores the
current status of each sample in consecutive order, and thus prevents the accidental duplication of operating steps (for example, it is
not possible to weigh the same sample twice).
Many of the application-specific settings are identical to those of the “Weighing” application. However, there are some additional
application-specific settings for Differential Weighing. In the following description, only settings that differ from the “Weighing” applica-
tion are described in detail.
12.2 Selecting the Application
If the “Differential Weighing” application is not already active, press the «D» key. Choose
the icon for the application in the selection window.
When the application has been selected, the display opposite appears. Some of the
specific function keys, as well as specific information fields for differential weighing, are
activated ex works. You can adapt these and other settings to your own requirements, as
described in the following sections.
Note: The figure opposite shows the application after the initial start. All function keys are
inactive, as no settings for series and samples have yet been made. Only one series is pre-
defined ex works. This series does not contain any samples (“Series 1” with 0 samples).
