SUB MENUS
These SUB MENUS become accessible if the instrument is set for flow. When meas-
uring flow, the area of the duct must be specified. Tables 3 and 4 show the input
range vs maximum flow and duct size. For a rectangular duct the maximum size is
specified in square feet or meters. For a circular duct the maximum size is specified
as the diameter. X, Y and circular dimensions are entered in feet with 0.01 foot res-
olution for

and 0.1 foot resolution for
FLOr = HI
, or entered in millimeters
with 1 millimeter resolution.
