Version: 1.5.0: New profiles for scales and balances

New device profiles for scales and balances

The following profiles have been added to Simple Data Logger (SDL):

Selecting a Device profile and clicking on Set default parameters for device allows you to easily set all interface parameters:

Each device profile also includes a “send immediately” command, which can be used with a timer to request the weight from the scale:

Reminder: SDL has a “Generic measuring instrument” and “Generic text device” profile for devices which do not yet have specific pre-defined profiles.


SDL now supports UTF-8 and ISO-8859-1 in addition to ASCII:

This means that data sent from your device that goes beyond the ASCII range can be correctly decoded, processed and displayed:

UTF-8 data received from an Ohaus scale
UTF-8 data received from an Ohaus Scout STX scale. Note that the Umlaute are correctly displayed, e.g. in “Überprüft”.

Note: The CSV file created by SDL is not affected by this setting, it is always encoded as UTF-8 (without a BOM).

Write data to file immediately

For performance reasons, SDL uses a write buffer when writing to the output file: Data is only written to the file when the buffer is full. For applications which require all data to be written to the file immediately, you can activate a new setting in the Output tab:
No buffer for output file

Note: If you want to concurrently access the CSV file created by SDL from another application, it must be opened in read-only mode. This can often be achieved by first pressing the Start button in SDL and then opening the file in the other application.

Default Regular Expression changed

SDL uses regular expressions to capture the relevant measuring value (e.g. the weight) from the data sent by your device. The default regular expression has been slightly modified in this version (a consequence of the “line feed” control character contained in the NCI format). You should not notice any difference.

Minor UI improvements and changes

This version includes many small user interface improvements. We’ve also moved the auto-start and auto-stop functionality from the Control tab to the Settings tab. This will allow us to add new functionality to the Control tab soon.
