Delta Q Alarms - What They Mean & How To Fix Them

 

Delta Q Operating Alarms

 


Eight alarms can occur during a sterilization cycle. All alarms are indicated by a “beeping” sound for one minute (or until “Clear/Start” is depressed) and an alarm display in the lower display window. The alarm display will remain visible until the problem is corrected or until the “Clear/Start” button is depressed.
