Hood Installation
The hoods are sewn in a trapezoidal shape so that
one open end forms a 14 inch square for
attachment to the base, and the other forms a
square or rectangle to fit its matching frame
assembly. Around each end of the hood an elastic
cord has been sewn into the hood. The cord is
pushed into the open side of the U-shaped
channels of the frame and around the top of the
base.
Attach the hood to the frame assembly first, and
then to the base unit. By stretching around two
corners the cord is slightly reduced in diameter
and is easier to press into the channel.
Note: Always locate the hood seams at the
corners of the frame and base.
After the first side is pressed into place each
remaining side can be done in a similar fashion.
The hood can now be attached to the base in the
same way. Do not attempt to set up the hood with
the hood support and dowels until the hood has
been completely attached to both the frame and the
base.

Hood Support Assembly
The hood support must be in the correct position
for hood set-up. This is accomplished by swinging
the long rods around so they project in a direction
opposite to the short rods which hold the springs.
In the corners of the base are a series of holes. The
ends of the long rods should be inserted in the
bottom hole of each corner. If it is later found that
the hood is not held as tautly as required the rods
can be moved upward to compensate.

assembly
The support dowels are now slid over the ends of
the short rods. The aluminum tips on the dowels
should be facing the top. If the 2 x 4 or 3 x 3 hood
is to be used, a set of 8-inch long dowel extensions
must be added to either end of the long dowels.
The hood can now be raised and the ends of the
dowels inserted in either the corner of the hood
frame, or into one of the ferrules (cups) attached to
the frame channels, depending on the hood and
frame size. Rods go into corners on the 2 x 2, 2 x
4, and 3 x 3 frames, into the set of inner ferrules
for the 1 x 5 frame, and in the outer ferrules for
the 1 x 4 frame. Proper tautness has been achieved
if the springs on the short rods of the hood support
assembly are slightly (but not fully) compressed.
Detachable Handle
For maximum flexibility in using or carrying the
Balometer, install the detachable handle. Simply
screw it "hand tight" into its mating thread on the
support plate above the range selector knob.
