7.4 Cleaning
During DUT-E operation mud or paraffin formation is possible on the surface of the measuring
probe pipes. Pollution of the cavity between the pipes of the measuring probe can lead to
significant increase of accuracy error.
ATTENTION: Mud coating inside the inner measuring tube does not affect DUT-E
normal operation. Examine the space between the tubes for mud and paraffin.
To clean the tubes wash them with the clean fuel.
It is also recommended to wash the screen filter as well.
ATTENTION: Avoid fuel getting on DUT-E head body, interface cable and its
connector when washing the tubes.
