Sample
Preparation
Samples used with the flexure accessory should
have the following specifications:
• No wider than the flexure platform
• Uniform width and thickness
• Thick enough to be rigid when placed on
flexure platform
• 7 to 10 mm long.
To load your flexure samples on the TMA 2940,
follow these steps:
1. Raise the furnace and rotate it clockwise to
move it off to the side.
2. Remove any previously run samples from
the stage and ensure that no residue remains.
3. Open the probe.
4. Place the flexure platform on top of the
stage
5. Place the sample on the flexure platform so
that it is centered across the points.
6. Position the sample and platform on the
stage under the flexure probe tip so that the
probe knife edge is parallel to the platform
points and is centered between them (see
Figure 4.8).
7. Press
ZERO LENGTH
on the keypad to
provide a zero reference point.
