General Q&A specific to RaceCapture/Pro. For app related questions post in the RaceCapture App forum. also see the <a href="http://www.autosportlabs.net/RaceCapture">RaceCapture Information Page</a>
Analog channel #8 is internal and not connected to the terminal block and is hard-connected to measure system battery voltage, if I understand what you're referring to.
Just set a sample rate and select the channel name "Battery" and you're good to go.
