bottom line, 10 degrees a minute to 900. hold 10 minutes next line up, 10 /minute to 1540 hold 150 minutes the top 2 lines are cooling. You could just enter 10 (the rate of cool) down to what ever you want, or the oven allows. Could be... 0 000 0 10 250 0 10 1540 150 10 900 10
The top 2 lines dont have to both be cooling. You could have 3 lines of heating and one line of cooling.
I dont know what that oven is. Is that a programmable hold ime or just showing the total time that step or all previous steps will take? You just want to heat up at 10/minute to 900 and hold 10 minutes. Then continue t heat at 10/minute to the high temp 1540 and hold for 150 minutes. Now cool at 10/minute down to room temp or what ever...200, 250
