4.3. Dual Pivot Frame Bar
The dual pivot frame bar provides mounting positions for probe holders as well as
ratchet levers which lock the dual pivot frame bar in place.
To pivot the frame bar, follow these steps:
1.
Rotate the dual pivot frame bar ratchet levers
(Fig. 16)
to allow movement of the
dual pivot frame
(see “Ratchet Lever” on page 12).
2.
The dual pivot frame will pivot both sides of the frame bar simultaneously
(Fig. 17-1)
.
Position the dual pivot frame at the angle required.
