User's Manual

Disconnect the Physilog® from the computer to update the time and date to the time when
the file has been created
Create a new text file each time you update the date, do not just rename or modify an existing
TIME.txt file (TIME.txt file previously created will update to the date it was created, so in the past).
The TIME.txt file will disappear from Physilog's memory when disconnecting the Physilog® from
the computer, therefore it is normal to not find it the next time you open the Physilog® on the
computer.
Via mobile application:
Connect the Physilog® to the Android companion application inside the “Remote control” mode.
Start a short measurement from the app, you can stop the measurement as soon as the stop
button is available in the user interface of the mobile application. Then disconnect the sensors or
completely quit the app.
