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.

“Calibration” 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

“Ov er view ” 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 “Screen messages”
on page 55 for information on error messages.)

14 Functional verification Welch Allyn Propaq CS Vital Signs Monitor

Required equipment

You will need the following equipment to verify that all functions of the monitor operate
correctly. All test equipment must be calibrated to function within parameters specified
by the manufacturer, and must be traceable to a national calibration standard.

Some equipment can be manufactured. See “Manufacturable test equipment” on
page 135 for information on manufacturable test equipment.

Safety tests

The following two safety tests, a risk (leakage) current safety check and a dielectric
strength integrity (hi-pot) test, must be performed whenever the monitor has been
opened for calibration or repair.

Note

A hi-pot test is only required if the monitor has been opened.

Risk (leakage) current test

A risk (leakage) current test must be performed to verify that the patient remains
electrically isolated from the power circuits of the monitor.

Check leakage currents using a Fluke (Dynatech/Nevada) 431F-1D safety analyzer or its
equivalent. The source current should not exceed 10μA rms. The sink current, measured
between the isolated patient connections (ECG) and the dc power input connector of the
monitor, should not exceed 20μA rms. See the analyzer's operator's manual for the
proper safety check procedure.

Dielectric strength (Hi-Pot) test

Because of the close spacings of the monitor's internal components and the critical
positioning of the insulation sheet within the monitor, Welch Allyn recommends that a
dielectric strength test be performed following any procedure in which the monitor is
opened.

WARNING The Hi-Pot test is extremely hazardous. Only qualified service
personnel should perform this test. Conduct the test only on an insulated table
top, away from other people and equipment.

Use a Rod-L Model M100AVS5 high-voltage potential tester, or equivalent. Refer to the
Rod-L instruction manual for operating information and safety recommendations.

1. Set the parameters of the high voltage tester per the ECG input connector
specifications in the table below.

breakdown.

WARNING If any dielectric breakdown occurs, do not use the monitor. All
internal sheet insulation barriers must be properly installed. Check the monitor to
determine the cause of dielectric breakdown; then repair the monitor or return
the monitor to Welch Allyn for repair.

If the monitor has the Nurse Call Option, continue with steps 5 to 8:

5. Remove the ECG connection from the monitor and the tester’s high voltage output
lead.

6. Set the parameters of the high-voltage tester per the Nurse Call Output Connector in
the table “Summary of connection points and high-voltage test parameters” on
page 16 (be sure to reduce the test voltage).

7. Connect a 008-0634-XX Nurse Call Cable to the Nurse Call Output Connector on the
monitor. Connect the open pins 1 and 3 of the cable to the high voltage output lead.

8. Apply the test voltage for one second and check that the tester does not alarm.

13. Check the monitor display for sync markers on the ECG waveform.

14. Disconnect the defibrillator from the monitor.

Note

If the patient simulator does not also provide an appropriate ECG signal, the heart
rate value will be displayed as “– – –” and an alarm violation will occur.

15. Disconnect the ECG cable from the monitor. (Disconnecting an active channel
initiates an equipment alarm; press any key to acknowledge the discontinuance of
ECG monitoring.)

The following procedure verifies the operation of the invasive blood pressure channels.
Some models of the monitor have no IBP channels; skip this procedure if your monitor
does not support IBP. If your monitor has multiple IBP channels, repeat the verification
procedure for each channel.

Caution Many blood pressure simulators are not intended to be used as
calibration standards. Use only the blood pressure simulators specified in

“Required equipment” on page 14.

Note

If you are using the Fluke (Dynatech/Nevada) model 213A, 215A, or 217A patient
simulator, do not simultaneously monitor ECG and invasive blood pressure (IBP)
unless the modification to the simulator is performed as described in “Fluke

patient simulator modification” on page 137. If you do not wish to modify your

simulator, use ECG and IBP independently.
