Close the PicoLog Player software and locate the Player.pls file as follows:
C:\Documents and Settings\<User Name>\Local Settings\Application Data\Pico Technology\
C:\Users\<User Name>\AppData\Local\Pico Technology\
To access the Application Data/AppData folder you will need to enable the option to view hidden files/folders.
Find the alphanumeric folder containing the Player.pls and Recorder.pls files. Open the Player.pls file in a text file and find the following lines e.g.:
You can edit the Start and End parameters for the x-axis. Save the file, then open the data file again.
Hopefully, the new settings should take effect. Please note that you can save your settings files separately through the File -> Save as... menu item (you will need to change the Save as type to 'Settings files' (*.pls)).
I hope this helps.
