CNAP Calibration
Each time a CNAP measurement starts or the inflation pressure alternates between the dual finger cuffs,
CNAP automatically calibrates. Calibration consists of a pulse determination phase followed by an NBP
correlation measurement. During calibration a triangular wave (for pod firmware version 2.14.14.) displays
in the CNAP waveform area and then the message
CNAP @ Calibrating
displays and the CNAP values
are blank. After a successful NBP measurement, the CNAP waveform and CNAP values display.

Maintenance (CNAP)
Overview
This chapter describes the maintenance measures required to maintain the proper functioning of the
medical device. Maintenance measures must be performed by the responsible personnel.
NOTE
A “rectangular” or “square” waveform displays for previous firmware versions.

Calibrating
CNAP calibration is in progress. Wait until calibration is complete.
NOTE
Calibration could take up to 2.5 minutes.
Depending on the pod firmware version, a
triangular waveform or intermittent
ascending/descending angled lines (pod
firmware version 2.14.14) are displayed when
calibration is in progress. Since 15 minutes is
the maximum time between recalibrations and
includes this 2.5 minutes, the actual useful
duration for CNAP monitoring is 12.5 minutes.
This represents an 83% duty cycle.
WARNING
Risk of infection
Users and service personnel can become infected with pathogenic germs.
Disinfect and clean the device or the device parts before any maintenance measures and also
before returning the medical device for repair.
