Problem

The Isolight Puck Light Meter appears in Linux, but no values are available. Instead, "~~~" is displayed.

Solution

Provide the user permissions to read from USB devices:

Open a terminal window.
Run the following command:
```
sudo adduser <user> dialout
```
where <user> is the username of the Imatest user.
Restart computer.
