Before you begin:

  1. Verify at least one file version number listed on the Meter Updates page for AIM is of a higher version than the AIM Version, Filesystem or Firmware versions found in the AIM Config screen. If they are the same, no upgrade is necessary.

PC Procedures:

  1. Insert the memory stick (supplied with the meter) into a USB port on the PC.
  2. Delete all files from the memory stick.
  3. Go to and click on the “meter updates” tab.
  4. Right-click on the “Update AIM” link and save the zip file to the root directory of the memory stick. Use your company login and password when prompted.
  5. Double-click on the zip file to open, then extract all the files to the root directory of the memory stick. IMPORTANT: Make sure the files are extracted to the root directory and not extracted into another folder. Uncheck the “Use Folder Names” option if displayed.
  6. Remove memory stick from computer.

  4. Press “OK”.
  5. This upgrade process can take up to a few minutes to complete.
  6. When the upgrade is complete, press OK to reboot.
  7. The AIM meter will then upgrade and reboot. (If AIM does not power back up, press the power button).
  8. Verify that the AIM meter received the new code.

If using a brand new meter, it is necessary to update both the “application and database”.  Although there isn’t any harm in updating them separately, the instructions on the release notes are correct in that the procedure is to unzip the file then transfer all 4 files to the root directory of a USB drive, then navigate to the ”update firmware” option on the meter- or begin the recovery process if experiencing a crash.  Repeat the process a couple of times if the meter is unresponsive.
