Thanks,
I think I have it mostly whipped. I managed to decipher the data sheet
and changed it to the right settings for the thermocouple. It will go to
1372 degrees C.
I can monitor the output and use a butane lighter to heat the
thermocouple and see it cycle.
The only issue is it won't switch to Fahrenheit. I can live with that.
Hell, it is worth the money if you only use it as a pyrometer!
The controller is a bargain. It's the data sheet that sucks.
