The rubber winged cap of your EcO has 2 positions:

• Position 1 is called the standby position. The sensors are hermetically sealed in the cap with a liquid bottom. This position applies when you receive your EcO or for winter storage.

• Position 2 is the analysis position. Make sure that you can see the sensors of the probe through the 3 holes of the cap before you put the EcO in the water.

Here is an animation of the transition from the standby position (1) to the analysis position (2).
