The Whole Round Multisensor Logger (WRMSL) and Special Task Multisensor Logger (STMSL) are two whole-round systems which allow simultaneous measurements of density, magnetic susceptibility and Pwave velocity. The WRMSL and STMSL are the only two systems, which allow continuous core section measurements, one after another.
Note: Both tracks function the same way; however, WRMSL measures density, magnetic susceptibility and P wave velocity, whereas STMSL only measures density and magnetic susceptibility.
It is possible to set the WRMSL acting as the STMSL by changing the setup of the desired instrument. The screenshot below shows how to change the track type of the magnetic susceptibility loop used in the WRMSL to make it work as a STMSL.

Procedures
Preparing the Instrument
- Double-click the MUT icon on the desktop (Figure 1a) and login using ship credentials. For more information on data uploaduploading see the "Uploading Data to LIMS" section below.
- Double-click the IMS icon (Figure 1b). IMS initializes the instrument and checks the movement of the track. Once initialized, the logger is ready to measure the first section.
Note: For Calibration of the GRA and the Pwave, please see the WRMSL & STMSL User Guide.

2. In the Measurement Editor window, select the Instrument you wish to configure and then click in the Parameters window (Figure 2).
Figure 2. - Instrument Parameters window.
3. In the intrument DAQ Parameters window the user may alter the settings for each instrument (Measurement Interval, Edge, Acquisition Time, Setting the Instrument Online or Offline and Setting the Control of the measurements On or Off). Select Accept Changes. The changes will be written to the configuration file (Figure 3).

- Place section in core tray. Make sure sections are oriented with the blue endcap facing towards the instruments (Figure 4).

2. Click START. The Section Information screen is displayed (Figure 5).

3. Place the cursor in the SCAN field and scan the section label. SAMPLE ID and LIMS ID automatically fills. These This ID tags contain tag contains information on expedition, site, hole, core, section number and length.
Additional entry field options are the LIMS and MANUAL tabs.
Missing Top: Used if material is missing or was sampled at the top of the section. If used, the software automatically adjusts the offset.
Max. Length: Used if the core is shorter than the core liner. Measure the core manually and insert the value on the box. It is used mostly during hard rock measurements.
4. Click MEASURE. Core sections will be measured in sequence from the first to last section, generally we do not run the core catcher. Each section will move through the instrument by a pusher.
5. Density, MS and Pwave velocity data graphs are displayed in real time during acquisition (Figure 6).

8. After the last section is measured, place the 'Pusher End Sequence' (water core standard) on the track (Figure 7).

- 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 8).

3. To manually upload files, check each file individually and clip upload. To automatically upload files, click on the Automatic Upload checkbox.
