Fig. 4: Set-up on U-shaped core with coils, pole
pieces and U-shaped holder
Place the U-shaped core on a stable, level
surface.
Place coils over the core in such a way that
their connectors are facing the front.
Insert the U-shaped holder all the way into
the hole in the U-shaped core and secure it in
place with the knurled screw.
Place the pole pieces on the legs of the core
and secure them in place with clamps (see
Fig. 4).
Insert the circuit board into the attachment on
the console until the contact pins slot into the
multi-pin socket. Make sure the circuit board
is correctly aligned (see Fig. 5).
Insert the console with the circuit board at-
tached onto the U-shaped holder. Make sure
the board is held parallel with the U-shaped
core. You may need to turn the U-shaped
holder slightly (see Fig. 6).
Insert the magnetic field sensor into the cor-
responding attachment on the console.
Undo the clamps and move the pole pieces
as far as the spacers on the circuit board
(make sure the board does not get warped)
(see Fig. 7/8).
