Functional verification
Introduction
This functional verification procedure helps to confirm the proper operation of the Propaq
CS monitor and options. This procedure supports the requirements of routine preventive
maintenance. No monitor disassembly is required to perform this procedure.
on page 43 provides the full calibration procedures. Calibration may be
required if the monitor fails certain functional tests or after a circuit board is replaced.
Monitor disassembly is required for calibration.
Always perform this functional verification procedure after performing any calibration. This
procedure contains additional tests that are not included in calibration procedures.
The monitor Service Menus provide access to internal software routines that are required
during the functional verification procedure. Service Menus provide features to test and
verify the NIBP (cuff) channel, display, invasive pressure channel, and printer. Refer to
on page 5 for information about the Service Menus.
Self tests
Many functions, such as alarms, waveform and scale sizing, and printer control, are
software operations. During the monitor’s power-up self-test, the integrity of all
programming is checked first. If software testing is successful, hardware tests are
initiated. If all testing is successful, the monitor is ready for use. (See
on page 55 for information on error messages.)
