Fluke 85xx update v1.21_190828

To update a Fluke 8588A/8558A:

An empty USB stick (of greater than 10Mbytes) will be required. This should be formatted using the Microsoft FAT32 format.

Note: A Microsoft NTFS formatted USB stick is not compatible with the instrument.

1) Expand the downloaded ‘update’ zip file, and copy the contents onto the empty USB stick.
   Note: The USB stick should then have a directory called 'firmware', (containing a number of files), and, (at the same level as the directory) a 'README.txt' file.

2) Turn off the instrument, and then insert the USB stick into one of the front or rear USB slots, and then turn the instrument back on.
3) After 15 to 30 seconds the instrument will display a prompt asking for the USB stick to be removed.
4) On removing the USB stick, another prompt will be displayed to indicate that the update has begun. The update process should take no more than 40 seconds to a minute.
5) The update is complete when the instrument display’s the ‘DCV’ function screen, at this point it is safe to turn the instrument off.
