Calibration Table
To create the calibration table, the user will require calibration samples with known
concentrations; the concentrations should be determined by another method, such as
chemical assay, XRF, etc. The calibration samples must also be in a suitable form and
geometry similar to the local samples found on site. Once the user obtains the
appropriate calibration samples, they must perform five susceptibility measurements for
calibration and the creation of the relation table. The following table is to be used only as
an example.

It is recommended that multiple measurements be taken on each sample; use the average
value to populate the concentration table. Next, the user must transfer the concentration
table to the KT-10
Plus
v2; this can be done with Geoview following the steps beginning
on page 109.

Finally, the user must access the setup menu to select the output in concentration. Once
this final step is complete, the measurements on production samples can begin.
