6. Thread the hang-down wire up through the
thermocouple tube into the balance cham-
ber, and hook the top of the wire over the
top of the tube (see Fig. 2.14).
To make the hang-down loops easier to see, we
suggest sliding a piece of white paper into the
balance chamber behind each loop before you hook
the hang-down wire into it. (Do not forget to
remove the paper when finished.)
7. Grasp the top hook of the hang-down wire
with brass tweezers. Being careful to keep
the top hook pointing to the left, pass the
double bend through the hang-down loop so
the wire is hanging from the loop.
8. Unscrew and remove the tare tube.
9. Locate the tare hang-down wire in your
accessory kit.
10. Hold the wire in your hand so that the
doubly bent top hook is pointing to the left
and the bottom hook is pointing to the right.
11. Using brass tweezers, insert the tare hang-
down wire into the balance chamber on the
tare side and down through the hole above
the tare tube connection, taking care not to
bend the wire (Figure 2.15 on next page).
12. Being careful to keep the top hook pointing
to the left, pass the double bend through the
hang-down loop so the wire is hanging from
the loop.
