3.5.11 Firmware
Updates
3.5.11.1 Overview
The F71/F41 teslameter can update its firmware manually by attaching a
USB Type-C™ stick to the rear panel. However, the easiest method is to connect the
instrument to the internet via Ethernet or Wi-Fi, and update directly from the Lake
Shore firmware server.
Firmware comprises many files, aggregated together to form a Lake Shore Firmware
(LSFW) package. The teslameter stores versions of its LSFW packages in its internal
memory. This local memory location is called the “local repository”. This allows you to
downgrade firmware should you choose, since older versions will still remain on the
teslameter in the local repository. In addition, Lake Shore maintains LSFW packages
on a network server that allows us to deploy those packages to all teslameter custom-
ers. This is called the “remote repository”.
Lake Shore recommends enabling the “Notify when updates are available” setting to
ensure your teslameter firmware is up-to-date with the latest features and updates.
If used with a valid network connection, the teslameter will display a notification on
the notification bar as soon as an update is available, but will not apply the update
until instructed.
