To open files collected on the EM38-MK2 in the DAT38MK2 files program, an EM38-MK2 file must be converted from the data logger file extension (.N38) to the DAT38MK2 file extension (M38).

This is a common error that a user may not realize when dealing with EM38 survey results. Follow the directions below to properly convert these files.

DAT38MK2 Shortcut

1. Open the DAT38MK2 program by clicking on its shortcut.

If there is no shortcut for the DAT38MK2 program, click the Start Button on the computer and look under the heading “All programs” for it. The user may also be able to search for it after clicking the Start Button.

Convert EM38 Files

2. Pick the Convert Tab and select Convert EM38-MK2-1 Raw Files (N38) to Profile (M38) Files.

This is assuming that the user has already transferred the files to the computer via compact flash drive. Files can be transferred via serial cable. However, transferring with a serial cable tends to be difficult and not user-friendly.

3. Push the Input File Button and find the .N38 file that needs to be converted.

Convert EM38-MK2 Allegro Files to M38

This is an important reason that a user must give a file a relevant name to his or her files and directories. After selecting the Input File, push the Output File Button. The Output File Button asks the user to rename the new DAT38MK2 file and to save it to a directory of his choice. The old N38 file will be still around to access after creating the new converted file in case the new file becomes corrupt. Next, push the Convert Button. This will finish the process of converting the new DAT38MK2 file.

Newly converted files will not automatically open after being converted. If the user wants to open a newly converted M38 file, he click the File Dropbar Menu from the DAT38MK2 and select “Open Profile File”. From here, open the correct directory and select the M38 file to view in the DAT38MK2 program.
