D-D The Aquarium Solution H2Ocean P4 User Manual page 17

Set the time for pump calibration by selecting 'Add time' and scrolling through to the desired time.
This can be set up to 60 seconds. For increased accuracy, a longer calibration time is best. Please be
aware the measuring cylinder needs to be large enough to hold the volume of the water for the
calibration. For normal calibration, a time of 10-15 seconds is advised.
Tap on 'Add start' and the pump will run for the time selected in the previous step.
Once the pump has stopped remove the outlet hose from the measuring cylinder and stand the
measuring cylinder on a flat surface. Use the scale on the side to determine the volume of liquid.
Enter the volume of liquid collected in ml by tapping in the space next to "Enter volume".
Select calibration complete at the bottom of the page and the pump will calculate the flow rate from
the time and volume you have entered. The chosen pump head is now calibrated.
