After initial pressure differential reading is taken, refer to flow rate charts to obtain flow rate based on pressure differential and valve setting. If flow rate is in excess of that specified, turn indicator towards closed position, noting pressure drop and valve setting and determining new flow rates from flow rate chart. Once correct flow rate setting has been established, slide memory stop clockwise towards open side of indicator plate until memory stop ring hits indicator plate. Do not force beyond this point. Tighten memory screw. Refer to Figure 1. The unit or system has now been balanced and the memory set.
