The caliper (Figure 3) is used to measure the dimensions of cylinder and rectangular prism-shaped samples. The information is entered in the MADMax software, which calculates the volumes of the solid samples.

As shown in Figure 9, above, double-click on the "Mass Wet (g)" column in the field adjacent to the sample to be analyzed. This will invoke the Balance Measurement dialog box as shown in Figure 11. The container number and the full Label ID of the sample will be displayed to ensure the correct sample was selected. Select the number of measurements to average (at least 300 is recommended, more if the sea state is high) and click "Measure." The measurement speed of the XS-204 balances is 5 Hz, so 300 measurements will take 60 seconds.
Figure 11. Balance Measurement dialog box. A typical expedition Label ID would be formatted as follows: 360-U1473A-21R-2-W 10/12-20127.
The next screen will appear in a minimal size with some detail hidden. If the window is expanded as shown in Figure 12, additional information can been seen.

If the user wishes, they can also look at the details of the mass results as shown in Figure 18. This is a summary of all of the parameters used to determine both the wet and dry masses with the parameters labeled by their database names.
Figure 18. Review wet mass results window.
The mass_dry and mass_wet components are the mass of the sample. The mass_dry_container and mass_wet_container components are the mass of the sample and the container together.

Before any pycnometer measurements can be made, the pycnometer cells must be calibrated. On the main screen, click the "Calibrate Pycnometer" button on the right side of the main screen in order to invoke the calibration window as shown in Figure 19.
Figure 19. Calibrating the pycnometer cells.
First select the standard to be used in the calibration. For the 35 cm3 inserts (Wheaton vials and aluminum cups), the best results are obtained by using "SPHERE_10," which is actually a 3 cm3 and 7 cm3 standard used together.
Once the standard is selected (again, the normal standard used is "SPHERE_10"), assign it to a pycnometer cell using the pull-down selector as shown in Figure 20. Use at least 3 repetitions for good precision between measurements.
Figure 20. Selecting the standard and then assigning it to the cell.
Click "Calibrate" once the standard and the cell have been assigned and the number of replicates is chosen. A window will appear for the cell that was chosen as shown in Figure 21. The first calibration step is to measure the empty cell. Ensure that the cell is empty before clicking "Done." The measurement will start immediately.

The pycnometer will step through its full measurement cycle once for each of the replicates selected (so three times if "3" was selected) as shown in Figure 22.
