Weight recording software – Data logger

Simple Data Logger (SDL) writes the weight from your scale or balance to a CSV 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.

Record the weight from your scale or balance for use in Excel

1. Connect your scale or measuring instrument

Connect your scale or balance to your PC. Our software supports RS232, USB (virtual COM port), Bluetooth SPP and TCP/IP (Ethernet, WLAN) connections.

3. Start recording the weight

Our software writes the weight values sent by your scale to a CSV file. If required, it adds the date and time to each line. The Plus version can also add line numbers and a custom text and use a timer to request the weight from the scale.

  • Data sent by your device (e.g. a scale, balance, serial bar code reader, etc.) has to be in ASCII format.
  • SDL can only capture one number (e.g. the weight) from each line of data sent by your device (or it can capture the entire line without formatting it).
  • SDL cannot connect to more than one device at a time.
