AMSspin is a Labview program written by Jeff Gee for Anisotropy of Magnetic Susceptibility measurements. The code has been modified to meet the needs of IODP. For detailed instructions on the use AMSspin and the files written by this program, see the vendor manual AMSspin – A LabVIEW Program for the Kappabridge KLY-4S and KLY-3S paper found in IODP Share\IODP Technical Manuals\Paleomag\Current\Kappabridge. This program is controlled with keyboard keystrokes. Be aware of what menu you are operating in as some keystrokes have multiple useshave multiple uses. AMSspin operational instructions are under construction as of December 2018.  The AMSspin program is undergoing modifications to allow for easy data upload.  AMSspin is not currently available on the Kappabridge PC.

To Start AMSspin:

...

  1. Make sure the sample holder is empty and the screw is securely in the holder (Figure 7). Also check that there are no obstructions in the path of the sample handler.
  2. Press N to name a new specimen and to begin a measurement.
    1. Do not put a sample in the holder at this time.
  3. Enter the TextID as the sample name in the pop up window and select OK.
    1. The TextID is required as the sample name for data upload
  4. After user enters a sample name, the program will move to the Measurement Mode menu (second menu).
    1. The blue bar in the center of the screen above the empty graphs will display "Ready for Sample Holder."
  5. Press the space bar to begin the sample holder measurement.
    1. The sample holder value will be displayed at the top of the screen when the measurement is complete.
  6. Evaluate the sample holder value
    1. The value should be small (E -5 or -6) and should be negative.
    2. If the value is high, the program will allow the user to complete the measurements, but will not allow the user to save the data.
      1. If the value is high, make sure the Kappabridge is away from the pole and that no computers/laptops/metal devices are next to the Kappabridge. Then press R to repeat the sample holder measurement.
      2. If the value looks acceptable, continue to step 6.
  7. Place the sample in the sample holder following the orientation scheme shown on the front of the Kappabridge and press the space bar to initiate the measurement.
    1. Between any of the measurements the user may:
      1. Repeat a measurement (press R).
      2. Start the measurement process over (press S).
      3. Return to the main menu (press M)
  8. When the holder returns to the up position, rotate the specimen to the second position and then press the space bar to initiate the measurement.
  9. When the holder returns to the up position, rotate the specimen to the third position and then press the space bar to initiate the measurement.
  10. When the holder returns to the up position, press space bar to initiate the bulk susceptibility measurement. The sample should remain in position 3 for the bulk susceptibility measurement.
  11. When bulk susceptibility is complete, the program will automatically move you to the third menu, Data Mode. You can choose to:
    1. Discard (D) the measurement
    2. Remeasure (R) the specimen. This option allows you to select which of the positions you wish to remeasure.
    3. Modify (M) the sample name. This option allows you to change the sample name before saving the data.
    4. Save (S) the measurement
  12. Press S to save.
    1. If a file is already selected, the new data will be added to the file.
    2. If no file name was assigned at the start of the measurement, the program will prompt the user to designate a file name or select a file.
  13. When the save is complete, the user is returned to the main menu.
  14. User may save the current holder value at this time by pressing H.
    1. This will save the holder value and you will not need to remeasure the holder for every specimen.
    2. When the holder measurement is being held it will say "OLD" under the Save SH heading at the top of the screen.
  15. To continue measurements, press N to assign the next sample name.
  16. If the holder value is saved, place the next specimen in position 1 and continue the measurements as in steps 6-11.
  17. Continue this process for each sample.

To stop the program press the red STOP button.

...

Uploads are completed using the MegaUploadaTron (MUT) application. For Anisotropy of Magnetic Susceptibility measurements, MUT requires an .asc and a .ran file. MUT only accepts the AGICO Sufar program data files. Currently the AMSspin data can not be uploaded.   To upload bulk susceptibility files, MUT requires the .ky4 file.

Currently the AMSspin data can not be uploaded. 
To complete an upload, place the files to be uploaded in the IN folder and select upload. MUT will not recognize if the same file has already been uploaded.  This will result in duplicate data being uploaded.
The Text ID must be the sample name for upload to work.  It is not possible to edit the names after the fact because the names need to be altered in the .ran file.
