VFC 311-USB FAQs
Once you have some recorded data, it’s very easy to view or download your data.
To do this, just plug the data logger into your computers USB port and visit vfc.local in any web browser on that computer. Once it loads, you will see the dashboard for the data logger where you can view or download any stored data.
If you press the button on the logger multiple times it will cycle through different screens, such as: MAX, MIN, then the WiFi signal strength, then back to the current temp.
While in the MAX or MIN screen (each of these will be performed separately) simply hold the button down for around 5 seconds or until you see two rows of dashes (—-). This will clear the MIN or MAX until the next time you go through the procedure again.
