Perkin Elmer Operetta (Lengg) - 1: Start up

Generally the system is always on, as this prevents condensation in the image formation path

Wait at least 30 sec. before you restart the Operetta CLS after a shutdown

Switch on the Operetta CLS (green button on the side)

The instrument is initialized (status light blinking green). As soon as the status light stops blinking (constantly green), the Operetta CLS is ready and can be used

Switch on the Harmony PC and log into Windows®

Notice It is recommended to let the instrument warm up for 1 hour before starting measurements. Otherwise drift as well as condensation artifacts can occur

Double-click the Harmony icon on the desktop

Log into Harmony. You will be given a user account after training

The Harmony Software has a bug where it indicates that it “isn’t connected to the device”

Override this connectivity error by pressing the “NEW” button under the C02

Afterwards you should see in the top-right corner that the software is connected when the plug symbol comes together
