Projects

Otii 3 Desktop App works on a project basis, which can be saved and later opened again.

An Otii project contains all the settings of the device under test (DUT) used, plus all measured measurement recordings of the multiple channels available for current, voltage, and power data.

Project storage

Otii 3 creates a lot of sample data when doing lengthy recordings.

This makes it important to choose the right storage location for your projects:

• Only store the project on a fast locally connected drive.
• When creating a new project, it is recommended to save it before starting a lengthy recording. This is because an unsaved new project is stored in the temporary directory of the OS.
• Do not store the project in a folder that is synced to a cloud service like OneDrive, Dropbox or Google Drive. On many installations the Documents and Desktop folders are cloud synced.
• Do not store the project on a network connected drive (NAS).

The size of the data for a one channel in one recording is:

    4 bytes * sample_rate * no_of_seconds

The default sample rate of the Otii Arc is 4 ksps, and for the Otii Ace 50 ksps.

If you have an Otii Ace you can change the sample rate down to 1 ksps.
