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

) on the display! Fault messages immediately affect the operation. Simulations
and positive zero return, on the other hand, are classed and displayed as “Notice messages”.

Caution!
In the event of a serious fault, a flowmeter might have to be returned to the manufacturer for repair.
Important procedures must be carried out before you return a flowmeter to Hauser.
