Firmware Update
For Products with a firmware version 1.03 or higher, firmware may be updated by the
product administrator with the front-panel USB port. New firmware versions are
available from the Fluke Calibration web page for the Product under the Knowledge and
Information tab.
For Products that have firmware versions below 1.03, contact Fluke Calibration Service
to schedule a firmware update as these versions do not support the USB firmware update
process.
Update instructions for Products that use version 1.03 and above:
WCaution
• Do not cycle the power or remove the USB device while the
firmware update is in process. These actions will cause an
instrument failure during the update process and require a
return to a Fluke Calibration Service center to correct.
• The Product automatically re-boots when the update
process is complete. Updates can take several minutes to
complete and the display screen will not illuminate until the
re-boot.
Note
Fluke Calibration recommends that you move all internal data files and
setup files from the Product to a USB device before the update of the
firmware.
Before the update process starts, verify that the current firmware is version 1.03 or above
by viewing “Firmware” under . If your firmware version is below 1.03, do not
continue the update process. You must return the Product to Fluke Calibration Service for
the firmware update.
