Hi Arran,
The system needs to be initially programmed on a computer, where the configuration settings are chosen, the device can then be disconnected from the computer for a length of time. The measurements can then be downloaded to the PC when the devices is connected to the PC and the software is running. You can also have the logger connected to the PC ata all times and the software running, there are a number of ways really.
This is really heading towards more of
support@picotech.com email.
However I would recommend you downloading the enviromon software, which you can find on our software download page.

If you have any further questions could you email me at
support@picotech.com and I can go into further detail perhaps I can also call you.
Kind regards
