Weight recording software

Simple Data Logger (SDL) writes the weight from your scale or balance to a file on your PC (with date and time). It can also be used with other measuring instruments, bar code readers, etc. sending data in ASCII format.

Connect your scale

1. Connect your scale

Connect your scale or balance to your PC. SDL supports RS232, USB (virtual COM port), Bluetooth SPP and Ethernet (raw TCP) connections.

2. Record the weight

Our software writes the weight sent by your scale to a CSV file. If required, it adds the date and time to each line.

Open in Excel, Google Sheets

3. Process in Excel, Google Sheets, etc.

You can easily open the file in Excel and other spreadsheet applications for further processing and visualization.

  • Data sent by your device (e.g. a scale, balance, serial bar code reader, etc.) has to be in ASCII format.
  • SDL cannot yet send commands to the device (it waits for incoming data).
  • SDL can only capture one value from each line of data sent by your device.
  • SDL cannot connect to more than one device at a time.
