Figure 23.3 Spinner, Polarizer BM-34(A), packing and packing diagram.
(4) When the presentation has been completed, press the power
switch.
(5) With the spinner motor turned off, but with the spinner
housing in position, any segment of the polarizer cycle can
be emphasized by rotating the pointer to the required position
on the scale. This operation is used to highlight a single
point in the demonstration. A slow-motion effect can be
obtained by moving the pointed back and forth by hand.
The scale is limited to 180, but within this arc all effects of
polarization can be demonstrated.
Caution: DO not rotate the spinner manually when power is applied.
