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).
Fig. 4 Set-up on U-shaped core with coils, pole pieces
and U-shaped holder
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
corresponding 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).
