Enter the name and accept it by pressing button that is followed by displaying windows for entering the values of ambient conditions (humidity and temperature).
Weighing T Selecting this option opens a screen with keyboard for entering name of a sample. Enter the name and accept it by pressing button that is followed by displaying windows for entering the values of ambient conditions (humidity and temperature). Caution: If the option is disabled in the working mode settings – set to then the software skips the need to specify the ambient conditions parameters.
Weighing T+ A Selecting this option opens a screen with keyboard for entering name of a sample. Enter the name and accept it by pressing button that is followed by displaying windows for entering the values of ambient conditions (humidity and temperature). Caution: If the option is disabled in the working mode settings – set to then the software skips the need to specify the ambient conditions parameters.
In case of a single series, and while weighing the following samples, the measurements can be carried out according to the following outline: weighing A, weighing T or weighing T+A. Each of samples saved in a series shall have a description on its data, i.e. a status, which informs a user on current process phase completed for an individual sample. On entering the database of s and previewing a series, the software opens a screen with saved samples in a selected series.
In case a given series includes samples for which weighing of initial mass (Weighing A) is already completed, it is possible to carry out final weighing (weighing B) for these samples. In such case follow below procedure: Select option: After selecting the option, the balance displays the main window, and the workspace area provides new data on an initiated process.
> pictogram On completing measurements of final mass for the samples in a a user can check the results in the database of s. To check the results, enter the database of s and select a . Select a sample to be previewed. The opened window provides the following information: displayed next to weighing data denote measuring cycles. Data on a specific can be printed or exported to a file.
18.17.3.
