Whoops, I think you will find this is the wrong way to LEAVE Eng Mode
"press FUNC , 0 , 0 , then eng code twice"
1. To ENTER Eng Mode
Func, 0, 0, then Eng code
2. To LEAVE Eng Mode
Func, 0, 0 , then Eng code (ONLY ONCE THIS TIME)
I expect what you have now done is to go back straight into engineering, therefore any key presses you have made since the second entering of the Eng code, has now altered the programming.
If I'm right, I would now strongly suggest you get an engineer in who is conversant with the Stirling 10 as it will need to be re-set to Factory defaults and re-programmed.
To help you through the defaulting (should not really do that, as we don't know who you are) and re-programming is not really something to be done through a Forum like this, would take weeks, and you can see how easy it would be for a simple mistake to be made, we would then be back to square one.
Good luck, hope I'm wrong, but ...............
ps
Unfortunately the Engineering Programming Manual is NOT available from Pyronix, you are only allowed the User Manuals, sorry
