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.
Note: The folder path is shown on the screen. Do not close this window during measurement.

4.

Run TK04 program and choose Measuring > Configuration.

5.

Set configuration parameters as follows:

–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: 6 characters or less; suggest Core-Type-Section (no special characters).
–Serial Number: number of repeat measurements at each 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.

For the HLQ (large and mini puck), set equal to the estimated thermal conductivity value of the measured sediment. The mini puck often gets better results without the thermal compound when measuring the standard.
–Measuring Time: set to at least 80 s (needle probe); set to 60 s for Puck.

Click Expert Options to configure Drift Control and Pause in Minutes (see Step 6).

6.

To configure Drift Control and Pause in Minutes in Expert Options:
–Drift Control (DCL): limit for the range of temperature drift allowed prior to heating and measuring. A larger number allows quicker but less accurate measurement. Default (unchecked) DCL = 10; Recommended DCL =. 10-20

–Pause in Minutes: insert a pause between single measurements; recommended = 10 min. This parameter does not apply when conducting a single measurement on each core or each core section.

1.

Confirm configuration settings shown in the lower part of the TK04 screen, insert the probe into the hole drilled into the sample, and click Start Measuring.

2.

Drift control (DCL) repeats until the criterion for drift (set in the Expert Options window) is met. Each drift control measurement takes 0.5 min.
For DCL = 40, drift control is <10 series (~5 min). For DCL = 10, drift control is <30 (~15 min).

3.

After satisfying drift control, sample heating and measuring begins, and temperature values are corrected automatically for the drift effect predicted from the last drift series. Elapsed measurement time is controlled by the value entered in Configuring Measurement Program > Step 5.

4.

Best solutions calculated by the TeKa SAM algorithm are shown on the screen. Note the sample result on the hand-written log.
