• 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 instruments, 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. You will
find a preprinted blank of the this form at the back of this manual.
