4.1 Error Messages and Troubleshooting

The following is an overview of the individual component groups, identifying the function of each component, its
potential malfunctions, the effects of the malfunctions on the measurement system, and the possible causes of
the malfunction and the procedure for correcting each malfunction. Conditioning cannot help minimize damage
in this case. It is thus of no consequence whether these malfunctions occur during conditioning or during a
sample measurement. Some errors can be remedied directly by the user or an in-house medical equipment
technician; other errors require return of the unit to the manufacturer.
