Fill the Hydrometer Cylinder:
•
Insert the Transfer Nozzle into the Hydrometer
Cylinder.
•
Slowly OPEN the Transfer Nozzle Valve until
solution starts to slowly accumulate into the
Hydrometer Cylinder. Allowing solution to fill down
the side of the beaker minimizes the creation of
bubbles within the solution (Figure 9, item A).
•
Fill the Hydrometer Cylinder approximately 2/3
rd
full.
•
CLOSE Transfer Nozzle and then press PAUSE on
the Display Panel.
•
Place Transfer Nozzle onto a clean surface.

Make sure the solution you gathered does not have
excessive amount of bubbles. To release excess
amount of bubbles from the solution gently tap the
Hydrometer Cylinder and/or gently swirl the entire
Hydrometer Cylinder until a majority of the bubbles
have been released from the solution(Figure 10).
