Get Empowered: Review Window and the Processing Method | Tip #62, Deriving Channels

By March 28, 2018
Empower tip-of-the-week

#62: In Empower Software, deriving a channel lets us mathematically combine two channels of data. What if we wanted to combine more than two channels? There’s a relatively new feature that lets us combine up to 10 channels of data, called Formula Based Derived Channel. Let’s see how it works.
