TMA Q Series Getting Started Guide

Cleaning the Thermocouple

Sample residue and dirt may interfere with the accuracy of the thermocouple readings. To clean the thermo-

couple:

1. Raise the furnace and rotate it clockwise to move it off to the side.

2. Remove the stage shield by lifting it straight up. (This is a friction fit.)

3. Remove the spring clip holding the thermocouple in place.

4. Hold the thermocouple away from the probe assembly, and clean it gently with a low

flame using a hand-held burner.

5. Reposition the thermocouple so that the tip of the thermocouple bends at a gentle 90°

angle and lies flat against the platform. It should be close to, but not touching the

sample as seen in the figure here. Note that a sharp bend could damage the thermo-

couple.

6. Replace the spring clip to hold the thermocouple in place.

7. Replace the stage shield.
