How do you run a Channel Check from the aRFR app?

swipe up to where the settings are and then choose channel check. Then select the first fixture and give it a level and then enter. So 1@5 [check][enter].

OMG! I hadn't noticed that menu extension bar despite using the app for a couple of years! DOH!

I've even been closing the app down and restarting every time I needed to connect to a different board and there was (and is) always a way to do it from inside the app.

Thanks for your help and sorry to have been such a duffer!
