Calibration/Maintenance Manual
Section 2—Installation and Service
The Calibration/Maintenance Manual provides instructions and information
for technicians to repair the Propaq at the replaceable module level.
Replaceable modules include circuit boards, large hardware items, such as
the air pump, check valve, chassis parts, and other parts easily replaced
without desoldering of surface-mount components and other small hardware.
Module-level repair allows monitor repair in minimal time and for a
nominal price for the replaceable module.
Because of the specialized equipment and knowledge required to
manufacture and repair the Propag, Protocol Systems, Inc. recommends that
only Protocol’s authorized repair facilities provide component-level repair. If
repair by other than Protocol’s authorized repair facilities is required, such a
facility must have the necessary equipment to service and repair surface
mount technology (SMT) electronics as well as the specialized equipment to
service Propaq monitors. The Schematics & Drawings Set (orderable as
810-0334-10) and appropriate option section (SpO2 PN 810-0334-20, Printer
PN 810-0334-30, or CO2 PN 810-0334-40) provides schematics, parts lists,
etc. helpful in component-level servicing. Contact Protocol Systems, Inc. for
more information.

Functional The functional verification procedures verify proper operation of the
Verification monitor, oximeter, and printer. This procedure should be performed at
intervals or conditions listed in Table 2-1.
Self Test Many functions, such as alarms, waveform and scale sizing, and printer
control, are software operations. Since system software 1s automatically
checked during the monitor’s power-up self-test, all software functions work
normally if no error messages appear during the power-up sequence. (Some
error messages indicate hardware failures.)
The Service Menus Service Menus are provided to facilitate functional verification. The Service
Menus (Figure 2-1) contain several functions for testing and verifying the
Cuff channel, display, invasive pressure channel (models 104 and 106 only),
and printer. During the functional verification procedure, the Service Menu

CO Functional This procedure verifies CO2 accuracy. If the verification test results are
Verification within specifications, board calibration is not required.
Functional verification and calibration procedures require calculations of
local barometric pressure and partial pressure of the test gas source (in
mmHg) to compare to Propaq displayed values.
Determine Local Barometric Pressure
1. Determine local altitude above sea level. For worldwide locations,
obtain altitude from local geological maps (U.S.G.S. maps in the United
States) or other local references. Refer to Table 2-3 to determine local
uncorrected pressure (LUP) for established altitude.
2 Determine ATIS reported pressure (inches or millimeters of Hg).
For U.S. locations, consult local telephone directories to obtain the
Automated Terminal Information Service (ATIS) number, which 15
typically listed under United States Govemment Offices, Department of
Transportation, Federal Aviation Administration, Air Traffic Control
Towers. Among various statistics reported is the “altimeter”, which 1s
given in four integers. The four digits represent the barometric pressure
as referred to sea level, in units of inches of mercury, with an assumed
decimal point occurring between the second and third numbers.
For worldwide locations, equivalent altimeter statistics, in millimeters of
mercury, may be obtained from local agencies.
The difference in altitude between the calibration site and the ATIS
site should not be greater than 30 m or 100 ft.
3 Determine local barometric pressure using LUP and ATIS. Apply the
ATIS and LUP values to the following formula to calculate the local
barometric pressure (mmHg):
Local Barometric Pressure =
0.033421 - LUP - ATIS (ATIS in inches of mercury)
000131579 - LUP + ATIS (ATIS in millimeters of mercury)
Step 1: The user's altitude is 5000 feet. The LUP from Table 2-3 is 632.3:
Step 2: The reported ATIS is 30.09 (“Altimeter: three zero zero niner.”)
Step 3: Multiply 632.35 (LUP) times 30.09 (ATIS) times 0.033421
Local Barometric pressure = 635.92 mmHg
Step 1: The user's altitude is 1000 meters. The LUP from Table 2-3 1$
Step 2: The reported ATIS is 764.29 mmHg.
Step 3: Multiply 674.11 (LUP) times 764.29 (ATIS) times 0.00131579
Local Barometric pressure = 677.92 mmHg

Functional Verification Procedure
This procedure verifies CO2 accuracy. If the verification test results are
Within specifications, board calibration is not required. If verification test
results exceed specification limits, calibration as instructed in Section 3
MAY or MAY NOT be required—see Table 2-4 for possible sources of
errors in testing. Before proceeding to calibration, check test parameters as
indicated in Table 2-4 to minimize errors.
1. Connect a CO2 sensor with airway adapter to the Propag CO2 input
2. Power the Propag on and use the menu keys to disable the patient
alarms. Set the CO2 measurement UNITS to millimeters of mercury
3. Allow the monitor and sensor to warm up for a minimum of 15 minutes.
Possible errors may be caused if the area has high background
CO? levels or if CO2 has been forced outside of the airway adapter
and into the sensor itself To reduce background CO2 level, the
area should be well ventilated and, preferably, the technician
should be the only person present. If CO2 has been Jorced into the
sensor, allow 24 to 48 hours for the CO; to dissipate.
4. After 15 minutes, check the CO2 reading (of ambient room air) on the
Propaq display to be 1 mmHg, +1 mmHg.
5. Procure two standard rubber test-tube stoppers and open a 1/8" to 1/4"
hole through each. Install the stoppers into each end of the sensor
airway adapter. Via the tubing/fitting combination, connect the CO2 gas
source through the hole in the stopper on one end of the airway
adapter. Leave the hole in the stopper on the other end of the airway
adapter open.
Before performing steps 6 and 7, convert the percentage of the gas
source to partial pressure (mmHg) as instructed earlier in this
6. Introduce a flow of test CO; at a rate of 60 to 200 ml/min into the
sensor airway adapter.
7. For test gas calculated partial pressure values of 30 mmHg or less,
check the CO2 reading on the Propag display to be within 3 mmHg.
For test gas calculated partial pressure values greater than 30 mmHg,
check the CO2 reading on the Propaq display to be within +10% of the
partial pressure value.
If CO? test results are out of specification limits, refer to Table 2-4
Jor possible error sources. Verify test setup to minimize errors.

requires opening the monitor.
Patient Leakage (Risk) Current Test
Check leakage currents using a Dynatech/Nevada (formerly Neurodyne-
Dempsey) 431F-1D Safety Analyzer or its equivalent. The source current
should not exceed 10 pA rms. The sink current, measured between the
isolated patient connections (ECG) and the dc power input connector of the
monitor, should not exceed 20 uA rms. See the analyzer's operator's manual
for the proper safety check procedure. Table 2-5 lists the proper connections
between the monitor, power adapter, and the safety analyzer for each test.
Note: because of the all-insulated construction of the monitor, the Enclosure
Leakage Current Test to ground is not performed.

Dielectric Strength (Hi-Pot) Test
Because of the close spacings of the monitor's internal components and the
critical positioning of sheet insulation within the monitor, Protocol Systems
recommends that a dielectric strength test be performed following any

This test requires specialized equipment which may not be available at
hospital repair facilities. If that is the case, Protocol Systems, Inc., will
perform the safety test for a nominal charge with one-day turnaround. See

displayed and saved in trend memory. To deactivate, turn Propaq off and
then on.
message appears when the Propaq is first turned on, it generally indicates a
drained lithium battery. The monitor can be used, but all settings will return
to factory defaults each time the monitor is turned off and on. Replace the
lithium battery as soon as possible.
ECG Messages ECG FAULT. Indicates ECG lead fault for one or more leads. An
equipment alert window appears, indicating which lead or leads are faulty.
Check ECG lead wires, electrodes, and cable.

Invasive Pressure
Propag 100-Series Monitors
The invasive pressure channel can produce messages that appear in the time
of day window, the blood pressure numerics window, and the equipment
alert window.
The following messages appear in the blood pressure numerics window.
Px NOT ZEROED. This message appears the first time a transducer is
connected to the monitor. It indicates that no zero reference has been
established. The monitor displays the pressure waveform, but to protect
against erroneous readings, the pressure waveform scale is not displayed.
Px ZEROING. This message briefly appears as the transducer is being
Px ZEROED. This message appears after the zero value has been accepted.
It remains for eight seconds and is replaced by. the current pressure values.
After zero acceptance, the pressure waveform scale appears.
Px ZERO REJECTED. This message appears after unsuccessfully
attempting to acquire a zero reference value. The message remains until the
CANCEL button is pressed. Causes of unsuccessful zeroing may include an
incompatible or defective transducer or cable.
Px CANCELED. This message appears after the CANCEL button is
pressed and remains for eight seconds.
The following caution messages can appear in the time of day window
above the heart rate.
P1 FAULT (P2 FAULT). One or both of these messages appear when a
transducer fault is detected. An equipment alert also occurs. (See the
following equipment alert messages.)
The following equipment messages can appear in an equipment alert
window. A caution message also appears in the time of day window.
TRANSDUCER NOT DETECTED. This message appears when the
Propaq detects that a transducer connection is broken. The transducer
connections and the transducer should be checked.
TRANSDUCER SHORTED. This message appears when the Propaq
senses a short in the transducer. The transducer should be replaced.
INCOMPATIBLE TRANSDUCER. This message appears when the Propag
has the Hewlett-Packard Connector-Compatible option, and an HP1290A
invasive pressure transducer has been plugged in. The HP1290A is not
compatible with this option; use only approved transducers listed in Section
6 of the Propaq Users Guide for Version 8 software.
Since both pressure channels use the same hardware. an
incompatible transducer plugged into one channel will likely cause
false readings on the second channel as well even if a compatible
transducer is plugged into the second channel.

Propaq to the ac power adapter.
continually recalibrates the cuff channel to ensure it can properly make cuff
determinations. If this message momentarily appears and then is removed,
the cuff channel was able to calibrate itself and the cuff channel is properly
operating. If this message continuously appears, the cuff channel could not
be properly calibrated and must be disabled using the DISABLE button.
Once the cuff channel is disabled, normal monitor operation continues, but
the cuff channel cannot be used. Repair is required.
CUFF FAULT: MEASUREMENT TIME OUT. A valid cuff measurement
could not be determined within 3 minutes. This could be due to patient
motion, arrhythmia, or other environmental influences such as transport
vibration. Try the measurement again.
CUFF FAULT: EXCESSIVE ARTIFACT. Too much patient motion,
patient arrhythmia, or sources of external cuff movement can cause this
CUFF FAULT: NO PULSES DETECTED. The cuff may not be on a
patient or properly applied to the patient.
CUFF FAULT: NO CUFF. During cuff inflation the detected pressure did
not sufficiently rise. Check that the cuff connection is tight, and take the
measurement again.

the patient.
CUFF FAULT: BLOCKED VENT. The pressure in the cuff cannot be
vented to the atmosphere. Inspect the vent hole for blockage.

properly inflate the cuff. Check the hose and cuff for obvious leaks, such as
the O-rings in the hose connections.

the Patient Overpressure Safety Circuitry, which then disables the pump and
removes pressure from the cuff. When either case occurs, this equipment
message is displayed. Check the hose, press DISABLE, and try taking
another measurement.
If the Patient Overpressure Safety Cirtuit (Recharger Board) has been
activated, this message is displayed. This message is displayed several
seconds after the beginning of an attempted CUFF measurement, or if the
pressure remains above 5 mmHg for more than 2 minutes after an attempted
CUFF determination has ended. The cuff channel is disabled and the Propaq
must be turned off, then back on before the cuff channel can be used. If this
message reappears after cycling power, service the Propag.
The following messages can appear in’ the cuff status window (the upper
right corner of the normal status window area).

The following messages can appear in an equipment alert window. A
temperature caution message also appears in the temperature numerics
window when one of these messages appears.
PROBE NOT DETECTED. This message occurs when the Propaq has
successfully measured temperature and a probe 1s disconnected. Reconnect
the probe and acknowledge the equipment alert by pressing any menu key.
PROBE SHORT OR OUT OF RANGE. This message usually indicates :
probe problem. However, the temperature being measured may be beyond
the range of the probe or the range of the Propag. If the probe is correctly
applied to a patient who you believe has a measurable temperature, replace
the probe.
CALIBRATION ERROR, TEMP DISABLED. This message appears whe
the Propaq has detected that the temperature circuitry common to all
temperature channels is out of calibration. (This occurs when the values
obtained during auto calibration check do not match those obtained during
auto calibration.) The temperature channel is disabled until the Propaq 1s

NO SENSOR DETECTED appears in the equipment alert window and
indicates a probe has been disconnected from the monitor after being
plugged in for a few seconds.
Pressing DISABLE deactivates the alert, removes the SpO2 plethys-
mograph, and deactivates the channel
If an SpO2 sensor is subsequently connected to the Propag, the channel
becomes active and performs its self-calibration.
SEARCH is displayed in the numeric window after the Pulse Oximetry
sensor is first connected to the monitor During this search time, the SpO2
channel tries to detect blood pulsing through the measurement site. Once the
measurement has been established, the OXygen saturation value is displayed
in the numeric window.
SpO2 SRCH alternates with the time of day whenever the channel cannot
detect a pulse for SpO2 measurements after it has successfully measured
Oxyten saturation. While this message is displayed, ??? is displayed in the
numeric window and the SpO2 channel searches for blood pulses at the
Sensor site.
NO C-LOCK. SpO2 is active with C-LOCK function turned ON, but a QRS
event cannot be detected. Check all ECG lead Wires, electrodes, and cable.
PRNT FAULT. Problem with the printer: low battery, overheating, out of
paper, paper door open. Check the printer paper, paper door, and general
functionality of printer. This alert message 1s displayed in the time of day
CO? messages can appear in the equipment alert window and in numeric
zones, as follows:
DISABLED (listed here in order of priority, highest priority alert first)
equipment alerts display UNCAL in the CO2 numerics zone, and the CO,
waveform is displayed without range scales.
If more than one alert occurs at the same time, the highest priority alert is
displayed in the equipment alert window. When an equipment alert is
acknowledged or its alert condition ceases, any lower priority alerts still
active remain in effect but do not generate new equipment alert screens.
During warm-up, WARM UP is displayed in the CO2 numerics zone, and
the waveform is displayed without range scales.
The breath rate numeric is not affected in either case. If the printer option 1s
present, INVALID is used in place of SRCH, UNCAL and WARM UP.

Fatal Error raul errors are errors, detected by software, that indicate the Propag is no
Codes longer able to function properly and must be retumed to Protocol for service.
When a fatal error is found, the software attempts to put the error message
and its number on the Propaq display. All monitoring functions are locked
out. Fatal errors are therefore distinct from equipment alerts, which permit
reduced monitoring capability.
Fatal errors are indicated in the following format:
х - ууу
x=0 indicates a problem found by the Display Control Processor
(DCP), i.e. non-isolated, section of the Propaq Main Board.
x =1 indicates a problem found by the Data Acquisition Processor
(DAP), ie. isolated, section of the Propag Main Board.
X=2 indicates a problem found by the Printer Control Processor on
the Printer Main Board.
x =3 indicates a problem found by the SpO2 Control Processor
(SCP) on the SCP Board.
x=53 Indicates a problem found by the Main Stream Processor
(MSP) on the MSP Board.
УУУ Indicate specific types of problems. Detailing the nature of
these problems is beyond the scope of this manual.
(Furthermore, these yyy codes change from one software
version to another.) Contact Protocol Systems, Inc. for more
details and/or send the monitor to an authorized Protocol repair
center for repair.
