Firstly set up Plug-in Mode to use the Clarity M plug-in as a sound source for the Clarity M meter.

When the Clarity M is set to Plug-in, the input will automatically be changed to Plug-in, note that changing the input causes the meters to reset.
When you switch to Plug-in Mode, a prompt will appear advising you to eject the Clarity M from your PC (the first time the Clarity M is switched on)

Please open your DAW and insert the plug-in on the track or bus of your choice. Keep in mind where it falls in relation to other plug-ins that might affect the metering. The exact process varies depending on your software

Once the plug-in is inserted in the signal chain in the desired location,  you can begin metering on the Clarity M hardware unit.
The connection status is indicated on the right side of the plug-in window, a successful connection is indicated with a green circle and “Connected to Clarity M”  is displayed.

The “Not connected” status might happened if another instance of the plug-in already exists on another track,  this will be identified by a yellow circle and a text box will notify you where the plug-in is currently active, if you click on the “Take Over” button this will allow a connection between the hardware unit and the new plug-in location and it will state “Connecting...”

Any connection problems are indicated by a red circle. This could be caused by a number of things but the main reasons are; if the USB cable is not connected, the Clarity M unit is powered off or USB Mode is set to Disk Drive.

Note: Most DAWs offer the capability to move or drag plug-ins from one track/bus to another, and this is also possible with the Clarity M.

Also you need to consider that most DAWs automatically offer an ON/OFF switch for plug-ins, accessible inside the plug-in window and/or the track itself.
Muting the plug-in will stop the data stream but will not shut down the connection.
When you select the “Follow Transport” option, this will automatically start the measurement when the DAW is in Play mode and stops it when the DAW stops.

When selecting “Reset on Play” this automatically resets the meters when the Play icon is pressed, or when the DAW starts to play in “Follow Transport” mode. You need to consider that the Reset parameter can also be automated using the DAW's automation feature. This process will vary depending on the software you are using.

When it comes to track information, this section displays the track number, name, and channel configuration.
Some DAW programs can automatically supply this information to the plug-in.
 In cases where this is not supported, you can enter the track name and number manually.
The number and name are stored within the project, allowing them to be recalled when you open the project again.

The track configuration mode will also be listed in this section (mono, stereo, 5.1).
When “Take over on focus” is selected, a newly-created instance of the plug-in within a DAW project will automatically be connected to the hardware unit.
Otherwise, an instance of the plug-in that was already active will take priority and remain connected.

“Take over on insert” –
When it is selected, this allows any instance of the plug-in that is currently in focus to be automatically connected to the hardware unit.
