Installing the Stage
To install the stage on the TMA, check to make sure the
furnace is raised and off to the side. Then follow these steps
(refer to the figure here for illustration of the parts):
1.
Remove the stage shield by lifting it straight up. (This is a
friction fit.)
2.
Turn the large stage nut counterclockwise to remove it.
3.
Twist the stage retainer ring (with key slots) counter-
clockwise, and pull it up off the three posts.
4.
Remove the stage from the accessory kit.
5.
Slide the wave washer (washer with rippled edges)
down over the top of the stage so that it fits on the flange.
6.
Slide the stage retainer ring down over the top of the
stage so that it rests on top of the wave washer.
7.
Insert the whole assembly (stage, wave washer, and
retainer ring) into the stage opening, aligning the key
slots in the retainer ring with the posts.
8.
Press down and turn the retainer ring clockwise to lock
the assembly in position.
9.
Replace the large stage nut, turning it clockwise to install it.
10. Attach the thermocouple to the stage as follows:
a. Position the tip of the thermocouple so that it bends at a 90° angle and lies flat against the platform. It
should be close to, but not touching the sample.
b. Hold the thermocouple against the stage assembly,
and put on the spring clip to keep the thermocouple in
place (see the figure below).
11. Place the stage shield on
the stage, aligning the slot
in the bottom over the
thermocouple (see the figure
to the right).
12. Install one of the probes
as directed in the next
section. (Refer to Chapter 3
for guidelines to use when
selecting a probe.)
13. Rotate the furnace into
position over the stage.
