- Load ThermCon software in offline mode. Ensure that the Text_ID field is blank.
- Scan the core label using a scanner, then click Verify Sample.
- If login is requested, enter UserName and Password and then click OK.
- The folder path is shown on the screen. Do not close this window during measurement.
- Run TK04 program and choose Measuring > Configuration.
- Set configuration parameters as follows (see figure below):
- 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),
- Root Name: six characters or less; suggest Core-Type-Section (no special characters in the root name).
- Serial Number: number of repeat measurements at each measurement point (1–99 single measurements).
- Folder: path for saving data results.
- 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.)
- Measuring Time: set to at least 80 s, or for mini HLQ 60 s.
- Click Expert Options to configure Drift Control and Pause in Minutes (see Step 7).
