Procedure

Assemble the Balometer instrument on site

Check the anemometer for zero adjustment by placing the instrument away from any air flow, setting the range selector to the OFF position, and verifying that the meter reads zero. (If necessary, use a screwdriver to adjust the zero screw so that the pointer reads zero. Although the meter will typically read zero (within one division) regardless of how the unit is held, it is best to zero the meter in the position in which it will be used.)

Set the range selector to the highest reading in the desired direction, supply or return. This technique is to ensure that the meter will not be damaged by an over range condition.

Bring the Balometer or capture hood instrument into contact with the perimeter of the diffuser or grill to be measured. To assure maximum accuracy, the foam gasket along the top of the frame must be firmly in contact with the surface all around the opening. Take care to ensure that your body or other material is not accidentally affecting the reading by blocking or diverting the air flow at the base opening.

If the reading is found to be below the full scale of the next lower scale, the range selector may be switched to the next lower scale.
