Olympus Delta Handheld XRF:Quick Start Guide- Computer System
Introduction
The Handheld XRF gun makes contact elemental measurements on section halves and prepared powder mounts. The XRF emits a primary X-Ray beam that bombards the material and excites electrons. The movement of electrons emits secondary fluorescent radiation that is measured in the gun. These energy patterns are characteristic to elements and determine what is present.
The Handheld XRF can be run either independently or through an attached computer monitor. The Innov-x-Delta Advanced PC Software is available on both the gun and computer, and functions the exact same. However, layout and presentation of the software is different. For this reason, two quick start guides exist. This is the guide for XRF analysis using the attached computer system.

You will see this initial startup window (Figure 2). Click on the 'Import Data Only' Button. This allows data storage on the computer. Do NOT click 'Import to PC' as this removes all configurations from the gun.

Then Click the 'Start' button. This brings up a login screen where you will enter the following information and then click 'Login' (Figure 3):

You are now in the main measurement window. First set the Mode to measure in. The gun has a Geochemical and Soil Mode. Each mode has different scanning parameters which preferentially pick up some elements better than others. The gun will remember the chosen mode and does not have to be chosen each time a new measurement is taken or the Gun is turned off/on.
To access the Modes click on 'Mode' at the top of the screen (Figure 4). This directs you to the 'Mode' Screen and in the left panel you can choose between the Geochemistry and Soil modes. Click on each to see the features of each Mode and select the one best for your analysis.

Now that the Mode is set, establish the measuring time for each beam. Each Mode has preset measuring times but these are changeable. To access the Measurement Time click on the 'Setup' Button at the top of the screen (Figure 5). Then in Left Panel click on 'Test Condition.' This brings up a screen that shows the Minimum and Maximum time currently set for each beam. Adjust the settings to your liking and click 'Save'.

Note: If the minimum time is set to 1 and the maximum to 30, if the gun determines it has a good profile in less than 30 seconds it will stop actively measuring. If you want to ensure it measures for the full time, set the minimum and maximum time to the same number. Ex: Minimum 30s and Maximum 30s
Making a Measurement
...
When you turn on the gun for the first time you need to make a 'Cal Check' Measurement before any other measurements are taken. Place the gun in its stand as shown in Figure 6.
Figure 6. Handheld XRF Gun resting in stand.
Then click on the blue 'Cal Check' button on the bottom left of the screen (Figure 7). This tells the gun to measure the stainless steel disk located in the stand. This is an internal calibration which ensures the gun is measuring properly.

This measurement is taken when the gun is turned on and every 10 hours. When a Cal Check is needed the white bar will say 'Perform a Cal Check' and the 'Start' button will gray out and be disabled until the Cal Check is completed (Figure 7).
...
In the Analysis Window, click the blue button with three dots in the upper left corner (Figure 8). The white bar shows the current run number.

Now you are in the measurement naming window (Figure 9). Enter sample information here.
Figure 9. Test Information Window. A. Editable fields for each measurement: Run Number, Sample Name, Text_ID, Offset for SHLF, Comment. B. Save Button
Editable fields are as follows: Run Number, Sample Name, Text ID, SHLF Offset, and Comment (optional field).
Run Number: A sequential number increased by +1 with every measurement, ex: 1, 2, 3… This number will start at 1 for the measurement of the expedition.
Sample Name: Sample Name according to the sample or section half label. Ex: 366-U1234A-20F1-W
Text ID: Unique 11 digit ID for each sample or section half located under the barcode on the label.
Offset for SHLF: The point where a measurement is made on a section half, measured as distance from the top of the section. This field will only have a value for section half measurements.
Comment: A brief description of the measurement. An optional field.
Enter the run number. Then in the 'Sample Name' field scan your label. For a section half use the end cap label and the scanner labeled 'SECTION HALF'. For a powder mount scan the label on the mount with the scanner labeled 'POWDER'. This populates the 'Sample Name' and 'Text_ID' Fields. If measuring a section half enter in the offset, for all other measurements leave the offset field blank. You may enter a brief description of the measurement in the 'Comment' Field.
Click 'Save' in the lower right portion of the screen. If you do not click save the information will revert back to the prior run and there will be two measurements with the same name. The measurements are parsed by time so measurements will not overwrite one another there will just be multiple measurements with the same information.
Now that a Cal Check has been performed and the sample information is updated you can start measuring.

Take the gun out of the stand and either attach it to the FlexStand for powder measurements or screw it into the leaded shielding drape for section half measurements (Figure 10).

Press the green 'Start' Button in the bottom left of the screen to start the measurement (Figure 11).
Figure 11. Start Button
This can be done while in the 'Test Information' window or you may click 'Back' to go back to the Analysis page and then click 'Start'.
Record each measurement taken on the paper log sheets provided by the technician.
...
The gun writes one file per day that contains all the measurements taken in that 24 hour period. Until that file is exported the measurements are not permanently attached to the file. If files have not been exported do not disconnect the gun, turn off the software, or turn off the gun otherwise those un-exported measurements will be lost.
To export a file go the 'Set Up' in the top right and then click 'Data Management' in the left panel (Figure 12).

The Data Management Screen is now up and files can be exported. First select the date file you want to upload in the right panel (Figure 13). A 'Data' and 'Spectra' file need to be exported per file. The active filetype has the red check highlighted in the type Box. In the Figure below, the Data filetype has the red check so it is the active file-type. The Filename for each file needs to be the same. The file extension for the data file is ".csv" and the file extension for the spectra file is ".spm". Follow this naming convention: "MM-DD-YYYY"
Example: Data File: 03-17-2020.csv
Spectra File: 03-17-2020.spm
Note: If you would like a different data file-type let the technician know

Click the 'export' button for the data file and then repeat for the spectra file and click 'export'. After the files have been exported the measurements are attached to the file. Multiple exports can be done in the same day however the measurements will still be written to the same date file.
For example: 10 measurements are exported at 11:00 on 03-15-2017. Then 5 new measurements are taken and exported at 15:00 on 03-15-2017. The 03-15-2017 file now has 15 measurements that are exported in spite of 10 measurements being exported earlier in the day.
