Figure 24 Choose yes to make the spectrometer configuration the default settings. The spectrometer has now been configured. Figure 25 Exit the software.
OM17-P4000VIS-NIR Setting Port Order 1. Check Device Manager for port order (Start settings control panel system hardware tab device manager double click ports) 2. Ports will be listed in order, as they should be set in software. Auxiliary case ports Spectrometer case ports Figure 26 In this example the order to set the ports would be as follows: (see Figure 25.
OM17-P4000VIS-NIR 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.
OM17-P4000VIS-NIR Section 4 Field Operation - Electronics Operating software - 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. Set software for either probe or shank mode.
OM17-P4000VIS-NIR How to take Manual Reference In order to calculate reflectance a dark and reference measurement must be taken initially when the software starts, and then every 10 minutes to ensure all measurements are accurate and to compensate for any discrepancies in the spectrometer or light source due to temperature. The software will alert the user when these conditions occur by displaying Take manual reference in the system message as well as the ref check light flashing.
OM17-P4000VIS-NIR 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; and B) transforming the data to a master set of data provided by Veris. A) Before running the external references make sure the window on the probe and the window on the reference are clean.
OM17-P4000VIS-NIR ER buttons Indicator light will be yellow or green Figure 7 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. 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.
OM17-P4000VIS-NIR Master data file, which will be used to transform slave (master file provided by Veris) External reference data that was just taken. 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. Compares the offset of the previous transform the current transform Master and slave data with transform applied master is black and slave is grey.
OM17-P4000VIS-NIR 2. Data Acquisition – The collection of spectral and auxiliary data in the field. Data is streamed to a file in a compact format. Pressing the PROBE button stores spectrum data as absorbance and auxiliary data, which includes EC data, the PROBE button key has been pressed again or the probe pulled out of the ground. 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 the program is in LOG mode.
OM17-P4000VIS-NIR 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. Note: Make sure to run through the setting the integration time procedure after starting up system for the first time or after switching between probe and shank mode Auxiliary data can be scrolled through by pressing the up or down arrow to the left of the indicator.
OM17-P4000VIS-NIR 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 the probe is pushed down 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 probe at any time in Data Acquisition mode. Absorbance should be highest for ER3 and lowest for ER4.
OM17-P4000VIS-NIR 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. There are 384 total wavelengths. Once all the data has been filtered and the complete light is green press close window or F12 to return to main interface. Graphs of each principal component; this is an ASCII text file and may be imported into other mapping software.
OM17-P4000VIS-NIR 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.
OM17-P4000VIS-NIR 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).
OM17-P4000VIS-NIR 7. Interpolation – Uses a Gaussian weighting to average spectra near a sampled location, so the data can be matched up with properties of interest for calibration. Spectra near to the location are weighted higher than spectra far away. Also, this will interpolate several probes into one value if desired. Outputs a file named spectra@locations.txt to the working directory. This file contains the spectra and auxiliary data for each sampled GPS location.
OM17-P4000VIS-NIR Interpolation (continued) Figure 16 This example on the left shows the interpolated output vs. the sampling depth increments. If a core was taken and cut into 10 cm depth increments the output file will show 05 cm thru 95 cm, but the 05 cm data corresponds to the interpolated value using 0-10 cm data, not the data at precisely 05 cm. This continues down the probe until through the 95 cm measurement.
OM17-P4000VIS-NIR Importing sample locations for interpolation 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. Exit the Veris Spectrophotometer Software once these steps have been completed.
OM17-P4000VIS-NIR 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 probe on the probe bench top stand. Place a soil sample in the sample holder and place the holder against the face of the probe window. Use the sample button or F4 to store a dark, reference, and then a sample spectrum.
OM17-P4000VIS-NIR Test/Example Data In order to gain experience with the software before mapping, test/example datasets are included with the Veris software. This allows the user to experiment with the system, without logging data or having GPS signal. 1. Start Operating software (Start programs Veris Spectrophotometer Software Veris Data Processing) 2.
