Updating the instrument software
Under www.testo.com/download-center you can download the
current instrument software (Firmware) for testo 350 (registration
required).
Control Unit and meas. box must be separated for updating
the instrument software.
Before the firmware update is started, the control unit's
rechargeable battery must be fully charged. If the battery is
not fully charged, this will affect the firmware update. The
flue gas analyser must then be sent in to Testo Service.
Once the instrument software has been updated, the
descriptions in the operating instructions will no longer
match the instrument functions. For the latest version of
the operating instructions, visit www.testo.com\download-
center.
