Fault description

Cause

Rectification

Measured value fluctuates 
around 10 … 20 %

Level

time

0

Various echoes from an uneven medi-
um surface, e.g. an extraction funnel

Check parameter "Material Type" and 
adapt, if necessary

Reflections from the medium surface 
via the vessel wall (deflection)

Optimize installation position and sen-
sor orientation

 

How to proceed if a repair is necessary

You can find an instrument return form as well as detailed informa-
tion about the procedure in the download area of our homepage. 
By doing this you help us carry out the repair quickly and without 
having to call back for needed information.
Proceed as follows in case of repair:

• 

Print and fill out one form per instrument

• 

Clean the instrument and pack it damage-proof

• 

Attach the completed form and, if need be, also a safety data 
sheet outside on the packaging

• 

Ask the agency serving you to get the address for the return 
shipment. You can find the agency on our homepage.
