9.2 System error messages
Serious system errors are always recognized by the instrument as “Fault message”, and are shown
as a lightning flash (

) on the display. Fault messages immediately affect the outputs. Simulations
and measured-value suppression, on the other hand, are classed and displayed as information
messages.

Caution!
In the event of a serious fault, a flowmeter might have to be returned to the manufacturer for repair.
The procedures on Page 8 must be carried out before you return a flowmeter to Hauser.
Always enclose a fully completed “Declaration of contamination” form. You will find a preprinted
form at the back of this manual.
