Seat the running tray between the foam pads in the
casting tray by placing one end of the tray against
the foam pad, slightly compressing it, then seating
the other end of the tray against the opposite foam
pad. (See arrows A and B in Fig 2.) The running tray
should lay flush against the bottom of the casting tray.
3
Place the casting tray assembly on a leveling surface
and level, using the spirit level on the running tray as
a guide. Check that the comb assembly leaves ~
~1 mm
of space between the comb bottom and the running
tray. Remove the level and the comb assembly.
Prepare the combs
1
Align the two slots in the comb with the loosened
thumb screws of the comb back. Tighten the screws
until the comb is just supported.
2
Place the comb assembly into a set of slots on the
running tray seated in the casting tray. Adjust the
comb so that the bottom of the teeth are ~
~1.0 mm
from the running tray. Tighten the screws to secure
the comb.
To run twice as many samples on the 15 and 20 cm
trays, prepare two comb assemblies and place one
near the cathode end, indicated by the black dot, and
one at the center.
