Exterior cleaning

When exterior-cleaning the Levelflex M, always use cleaning agents that do not attack the surface
of the housing and the seals.

Repairs

The Endress+Hauser repair concept assumes that the measuring devices have a modular design and
that customers are able to undertake repairs themselves (see Chap. 9.4 "Spare Parts" Page 72).

Replacement

After a complete Levelflex M or electronic module has been replaced, the parameters can be
downloaded into the device again via the communication interface. As a prerequisite, the data have
to have been uploaded to the PC beforehand using FieldCare.
Measurement can continue without having to carry out a new calibration.
• You may have to activate linearization (see BA366F – "Description of Device Functions" on the
enclosed CD-ROM.)
• New interference echo suppression (see Basic Setup)
After a probe or the electronics have been replaced, a new calibration must be carried out. This is
described in the repair instructions.
