1) System Check – This step calibrates the spectra data to known standards to ensure
data integrity. This is accomplished by A) manually placing four external reference
standards against the window and collecting spectra measurements for each standard,
then B) transforming the data to a master set of data provided by Veris.
A) After the Dark and Reference cycle has completed and the ref check light has turned
green, the system is ready for the external references. Before running the external
references make sure the window on the shank and the window on the references are
clean. References can be checked in any order and as many times as necessary.
When program state reads REST, the ref check light is green, and controller is in
neutral (N), place the correct external reference under shank and then press the
corresponding external reference button. If the External Reference (ER) failure light is
yellow, check to make sure the correct external reference was placed under the shank
and that the correct external reference button was pressed, then run the external
reference again. When ER light turns green or yellow, proceed to next reference. Once
each external reference has been run at least once, press end or F12. This will exit this
program and initiate the create transform program, which will take the data just acquired
and compare it to the master data to create a current transform. If the transform is
created successfully, then that transform will be applied to all spectra data acquired
during the acquisition.

Figures 3 & 4
Place the ER securely onto the shank wearplate. The dowel pins on the ER fit into four
allen-head screws on the wearplate. This aligns the ER in the correct position, and
magnets hold the ER firmly in place. The reference material goes towards the front of
the shank and lines up directly underneath the sapphire window on the wearplate. The
allen-head screws can get packed with soil after the system has had soil contact. A flat-
head screwdriver can be used to remove the soil so the ER can be put in place.
