9. All instrument data (density, magnetic susceptibility, Pwave velocity) are stored in C:\DATA\IN.
10. MUT is used to upload data to the LIMS database. See section "Uploading Data to LIMS" for more information.
11. Once uploaded, data is available to view on LORE and LIVE. If data is not instantly visible, please contact the PP technician.
Evaluating Your Measurement
The program will automatically calculate the velocity from its auto-picked first arrival wave. It will display the value in the "Velocity – Auto" box (see Figure 3) and display the auto-pick location line (Figure 12). If either of these do not look good, the following steps A, B, and C are suggested, in that order.
A) First Arrival Picking
The program's method of automatically picking the first arrival from the signal is a multi step process. For more information on how an auto-pick is made, see the user manual or ask the Physical Properties Technician.
To evaluate the auto-pick velocity, you need to look at two graphs.Auto-pick location line
The signal graph has several different displays, all accessible by clicking on different tabs at the top. Tip, you can zoom by pausing the program and clicking on the magnifying glass in the Graph Tools box, Figure 12. The first graph you need to examine is the stacked raw value ("RAW STACKED" tab), (Figure 11). Here you see the stacked measurements display with a vertical red line showing the location of the programs auto-pick of the first arrival wave. If the red line appears very near the first significant deviation from 0 on the Y-Axis, then the value is very likely reliable.
Figure 12. Raw Stacked signal display with red line indicating auto-pick location.
Uploading Data to LIMS
- Click the MUT Icon. Log in using database credentials.
- Once activated, the list of files from the C:\DATA\IN directory is displayed. Files are marked ready for upload by a green check mark (Figure 7).
Figure 7.- Main MUT screen
3. To manually upload files, check each file individually and clip upload. To automatically upload files, click on the Automatic Upload checkbox.
4. If files are marked by a purple question mark or red and white X icons, please contact a technician.
Purple question mark: Cannot identify the file.
Red and white X icons: Contains file errors.
5. Upon upload, data is moved to C:\DATA\Archive. If upload is unsuccessful, data is automatically moved to C:\DATA\Error. Please contact the PP technician is this occurs.
