Firmware Updates for the Fluke 744, 743B and 741B

These models have been out of production since 2011 and are no longer supported. The final version of firmware for the Fluke 744 is available at https://www.fluke.com/en-us/support/software-downloads/fluke-744-final-release-firmware-upgrade. Firmware updates for the Fluke 744 added HART support for additional HART transmitters, but did not affect other features. We never had firmware updates for the 743B and 741B.
