Glaze firing set-up

First glaze firing of the Skutt kiln at the center. Digital kilns are very easy to fire unless of course you press the wrong button! I was trying to clear the previous settings and pressed the Menu button. Bad idea. That, turns out, is designed to set specific temperature programs and possibly over ride and change default settings. Did Not want to do that but then couldn't exit that particular Menu. Somehow, I did manage to exit without changing any settings (wish I knew how I did that!). Set it up for a cone 5 firing, no pre-heats, no holds and then got a digital read out that was no where to be found on the on-line manual or anywhere on the internet for that matter. "COST" Could it mean the obvious. ..the cost of each firing or was it initials with meaning such as "cone offset system toggle" ???? I didn't feel safe pressing "start" until I knew what it meant. I emailed Skutt customer service, which is great, by the way. Yes, it was the cost of each firing! A very new feature that will calculate the cost of each firing if you enter the cost of your kilowatts. Good to know.
