5. Handle Attachment

Determine from the work to be done which handle arrangement will be
most convenient to use. Generally, if you are working from the floor, the
handle location near the bottom of the instrument will be most
convenient, while ladder work will be easiest with the handle installed on
the top of the range selector housing. Installation is accomplished by
simply turning the handle into the threads at either the top or bottom of
the range selector housing. Make sure that the handle is secure before
using. See Figure 5.

6. LoFlow Adapter

The LoFlow adapter screen can be used for measuring air volumes below
200 cfm (340 cmh, 95 l/s), but is strongly recommended for use only
when measuring very low flows, below 125 cfm (200 cmh, 60 l/s).
The LoFlow adapter is inserted by carefully pushing it into position
against the manifold on the side which the air will enter. (For example, if
the air will move through the hood to the base of the instrument, the
adapter goes on the ―hood‖ side of the manifold.) It is necessary that the
adapter be in very close contact with the manifold. Gaps of more that
/ " may cause reading errors. Take care not to distort the manifold

unless measurements of less than 100 cfm (200 cmh) are to be made. It is
strongly recommended that the adapter be used only when measuring
very low flows (up to 125 cfm, 200 cmh, 60 l/s).
This completes the assembly of the instrument. Proceed to the Operation
section for step by step instructions.
