  1. Load ThermCon software in offline mode. Ensure that the Text_ID field is blank.
  2. Scan the core label using a scanner, then click Verify Sample.
  3. If login is requested, enter UserName and Password and then click OK.
  4. The folder path is shown on the screen. Do not close this window during measurement. 
  5. Run TK04 program and choose Measuring > Configuration
  6. Set configuration parameters as follows (see figure below):
    1. Probe Number: serial number of probe to be used in the measurement (Note: results may be wrong by several percent if the wrong serial number is entered or by a factor of ~2 if the wrong type of probe is entered),
    2. Root Name: six characters or less; suggest Core-Type-Section (no special characters in the root name).
    3. Serial Number: number of repeat measurements at each measurement point (1–99 single measurements).
    4. Folder: path for saving data results.
    5. Heating Power: for the VLQ (needle probe), set to twice the estimated thermal conductivity value of measured sediment. For example, 2–3 is good for sediment. (See the Appendix: TK04 Recommended Heating Power for power guidance.)
    6. Measuring Time: set to at least 80 s, or for mini HLQ 60 s.
    7. Click Expert Options to configure Drift Control and Pause in Minutes (see Step 7).
    8. Enter comments.
