Pub# OM17-NIR Shank Setting Integration Time: The integration time is the amount of time the spectrometers collect the spectral data for averaging. It is important to have this set correctly because too much light will saturate the spectrometer, while too little light won’t allow the full range of the detector to be used. The integration time needs to be set before acquiring spectral data.
Pub# OM17-NIR Shank Section 3 Field Operations: Electronics Operating software – Software that will guide the user through the field usage steps. This will need to be completed every time the software is started. Open Veris operating software: Folder icon to select working directory. A field folder must be selected before any steps can be completed. Note: Each field or site must have its own folder. BEFORE STARTING: 1.
Pub# OM17-NIR Shank 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.
Pub# OM17-NIR Shank A yellow ER light indicates possible problem. Regard as a good reference unless transform step fails. Reference check light is green for good references and red for a failed reference. If a reference fails, press F2 to store a new dark and reference. Ref check light Auxiliary data can be scrolled through by the up and down arrows on the left of the indicator. Data corresponds to chart listed on the right of indicator. Note: a reading of –1.

This compares the slope of the previous transform to the current transform Previous transform will be a straight line the first time system is ran. . Raw master and slave data (external reference). The master is black and the slave is grey.
Pub# OM17-NIR Shank 2) Data Acquisition--electronics – The collection of spectral and auxiliary data in the field. Data is streamed to a file in a compact format. Pressing LOG button or ESC key stores spectrum data as absorbance and auxiliary data, which includes EC data, until LOG button or ESC key has been pressed again. No data can be logged if there is no GPS signal or there is a bad ref check. No data, including EC data, will be stored unless it program is in LOG mode.
Pub# OM17-NIR Shank These indicate the temperatures and the humidity of the system. If they are not within range (see specifications) the indicator light will be red, if this occurs the system should be shut down. Auxiliary data can be scrolled through by pressing the up or down arrow to the left of the indicator. The auxiliary data corresponds to the chart listed on the right of the indicator.
Pub# OM17-NIR Shank How to know you’re collecting high quality NIR measurements: a) Log light and GPS lights are both green b) Ref check light is green c) Spectrum absorbance doesn’t jump as unit is pulled ahead d) Absorbance spectrum shows a typical soil spectra pattern (Figure 52), and is changing slightly as the data is collected. e) External references can be attached to shank at any time in Data Acquisition mode. Absorbance should be highest for ER3 and lowest for ER4.
Pub# OM17-NIR Shank 4) Filtering -The spectra are compressed using principal components compression, and outliers are removed. Maps of each principal component (up to 10) are displayed, and the results of the PC analysis and filtering are output to ASCII formatted files. Score plots of spectrum data that indicate grouping of spectra. Loadings of each principal component. Number of outlying spectra removed during filtering. Total number of spectra. Wavelengths used by the spectrometers.
Pub# OM17-NIR Shank 5) Clustering – Clusters the principal components (PC's) of the spectra into the same number of clusters as desired sample points. When the clustering program opens it will ask if the settings are correct. The settings this refers to are the number of clusters or sample locations, and the number of PC’s to use for clustering. By default there will be 3 PC’s used and 15 locations to sample. If more sample locations are desired, then this can be changed at this time.
Pub# OM17-NIR Shank 6) Soil Sampling – Allows the user to navigate to the GPS coordinates of desired sample locations (from Step 5), and record actual sample locations. The actual locations that are saved during sampling program will be used for the interpolation of the spectra in the next step. Map of the proposed locations (black circles) and the actual locations (black squares).
Pub# OM17-NIR Shank 7) Interpolation – Uses a Gaussian weighting to average spectra near a sampled location. Spectra near to the location are weighted higher than spectra far away. Outputs a file named spectra@locations.txt to the working directory. This file contains the spectra and auxiliary data for each sampled GPS location. Once the interpolation begins it will ask if the settings are correct. The settings this refers to are a, b, and the depth increments.
Pub# OM17-NIR Shank How to import sample locations for interpolation with Veris software (versions 1.4 and later) This is only to be used when sampling is not completed in the Veris software. By following these steps the user could map a field and then flag the GPS locations where samples were collected and use those locations to get the interpolated values from the Veris software. Step 1: Collect field data, then extract and filter the data.
Pub# OM17-NIR Shank Bench top Usage To use the spectrophotometer to obtain measurements in the a bench top setting, first complete the system check as described in the field usage steps, then proceed to the acquisition. Mount the shank against the shank bench top stand (shown below). Place a soil sample in the sample holder and place the holder against the face of the shank window. Use the sample button or F4 to store a dark, reference, and then a sample spectrum.
