•
Place the U-shaped core on a stable, level sur-
face.
•
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).

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 corre-
sponding 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).
