SHMSL Quick Start Guide
...
The SHMSL (Section Half Multisensor Logger) makes point-source, contact measurements of magnetic susceptibility and color reflectance; as well as a surface laser profile. Split core surfaces, predominantly from the archive half, are measured.

Procedures
Preparing the Instrument
- Open MUT and login using ship credentials. For more information see the "Uploading Data to LIMS" section below.
- Double-click the IMS icon on the desktop (Figure 1). IMS initialize's the instruments and checks the movement of both Exlar actuators. Once initialized, the logger is ready to measure a section.

QE Pro Calibration
- The Instrument Calibration screen appears automatically if the QE Pro is out of calibration,.
- Click Calibrate Instruments to begin the calibration process, starting with the White calibration. The QE Pro integrating sphere lowers over the QE Pro calibration standard until contact. The Integration Time should be less than 0.55 seconds (Figure 12).
Figure 12.- White Calibration
Note: If the integration time increases, contact the PP technician. - Click Accept.
- After the White Calibration is complete, the Dark Calibration will begin (Figure 13). The difference between the calibration values of Dark Pixels and the Spectral Mean should be less than 100. If this difference is higher or if negative values appear on the spectrum, please contact the PP technician.
When finished click Accept. Figure 13.- Dark Calibration - After the Dark Calibration is complete, the normalize spectra will appear (Figure 14). Click Accept to apply the calibration.

Making a Measurement
NOTE: If you would like to change measurement parameters, please contact the PP technician.
...
- All instrument data (laser profile, MSP, color reflactance, and standards) are stored in C:\DATA\IN.
- Data is automatically uploaded to the LIMS database, and is available to view on LORE and LIVE. If data is not instantly visible, please contact the PP technician.
- 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 if this occurs.
Uploading Data to LIMS
1. | Click the MUT Icon (Figure 10). Log in using database credentials. |
2. | 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 11). |
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. |
