Remember to manually fill out the LogSheet as you are editing the sample information. For the current version of the logsheet, do not worry about the Run#, this will be automatically assigned and you can fill that in after the measurement starts. It is important to fill in the Time (in UTC) as this will help the X-Ray technician match up the sample with the measurement and correct any errors, if any, before uploading the data. The most important information is the sample TextID and the Offset (if from a SHLF) as these are unique values needed to upload the data to LIMS.

Note: The internal memory of the device is only 512MB (~1200 scans)! Therefore, the internal memory may need to be cleaned up several times an expedition to prevent locking up the device’s onboard computer. The X-ray technician will take care of this, but keep this in mind if you are performing a lot of measurements!

Setting Date & Time

...

To set the time, select on the main display screen. Then select and then select Date/Time from the available list. A stylus or fine pointed tool (non-metal, such as a wooden applicator stick) is helpful to access the small buttons involved in setting the date and time.

In the screen that displays (Fig. 1211), change the date by selecting on year, month and the numerical day. The time can be changed by using the selecting the hour, minute, second and AM/PM and using the small arrows to the right of the box to adjust the number. Please set the device to UTC time (NOT the same as ship operation time). If unsure what UTC time is, check the time on the nearest lab computer.

Once the correct date and time is shown (as close as possible), select ‘Apply’ and then ‘OK’ to exit the screen.
