Repairs

that customers are able to undertake repairs themselves. Spare parts are contained in suitable kits.
They contain the related replacement instructions. All the spare parts kits which you can order from
Endress+Hauser for repairs to the Levelflex M are listed with their order numbers on → ä 73 and
76. Please contact Endress+Hauser Service for further information on service and spare parts.

the data were uploaded to the PC beforehand using the ToF Tool.
Measurement can continue without having to carry out a new setup.
• You may have to activate linearisation (see BA245F – "Description of the instrument functions"
on the enclosed CD-ROM.)
