Oven status
SYSTEM SETUP
The oven enters the system setup state any time an action is performed such as calibrations, during

temporarily disable any non-critical alarms which may be affected, and the Yellow light on the light tower
will be on.

will occur. An alarm shutdown can occur when any parameter set for critical alarm goes over

too cold, Red = too Hot
