Caution!
• In custody transfer mode, error messages must be reset or confirmed manually. Error messages
are reset via the status input by applying a pulse.
• For certified devices subject to legal metrological control, faults can only be corrected by breaking
the seal. After repair by an Hauser service technician (provisional seal), the device must
be resealed by the appropriate standards authority.
• 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 duly completed "Declaration of Contamination" form
96. You will find a preprinted blank of the form at the back of this manual.
