[E�033]
Measurement disturbed
by heavy foam build-up or
turbulence�
• If possible, install the unit in a different position�
• If possible, prevent or exclude foam formation
or turbulences by taking appropriate measures

output a little)�
Measurement disturbed by
separation layers (e�g� oil
layer on water)�
Remove the oil layer by suction, stir the medium,
check the composition�
