Power Supply
The AC/DC converter transforms the AC power coming from the power plug into 48 V/120W
DC source and isolates the monitoring system from the AC power mains.The 48V is distributed
via power bus and supplies power to all the components of the system: The 56 V DC power
needed for the FMS, MMS and MMS Extension is created by an isolating DC/DC converter.
The CPU is supplied with 3.3 V and 5 V DC power. The transformation is performed in two
steps: The first DC/DC converter is a power regulator which reduces the variations caused by
load changes on the 48V power bus. The second DC/DC converter converts the power to the
needed voltage. Interface boards require a power of 10V AC.
CPU Boards
The CPU boards have an MPC860 50 MHz or MPC86x 100 MHz processor that provides a
number of on-chip, configurable interfaces. An array of 12 fast UARTS with configurable
protocol options are implemented in an ASIC (along with other system functions such as
independent watchdogs etc.), providing interfacing capabilities to measurement modules and I/O
boards. The serial interfaces can easily be electrically isolated. The main board contains
additional video hardware.
The CPUs provide two LAN interfaces to interconnect CPUs (via the MSL) and to connect to the
Philips Clinical Network.
The CPU capabilities are identical. Different loading options are coded on serial EEPROMs to
support the automatic configuration of the operating system at boot time.

I/O Boards
Interfaces to the monitor are implemented via I/O boards. The location of these boards is
restricted by general rules. The I/O slot designations diagram and the I/O matrix which outline
the I/O board placement rules can be found in the Installation Instructions section.
The following is a list of Interface (I/O) boards which may be present in your monitor,
depending on your purchased configuration:
- MSL
- Video (analog)
- Philips Clinical Network (LAN wired or wireless)
The specifications for the above listed interfaces can be found in the technical data sheet for the
monitor and in the Installation and Specifications chapter of the Instructions for Use.
The following diagram shows how data is passed through the monitoring system. The individual
stages of data flow are explained below.
19
Page 20
2 Theory of Operation Monitor Theory of Operation
Data Acquisition
Monitoring data (for example patient measurement data in the form of waves, numerics and
alerts) is acquired from a variety of sources:
- Measurement Servers
The Measurement Servers connected to the internal LAN convert patient signals to digital
data and apply measurement algorithms to analyze the signals.
- External measurement devices
Data can be also acquired from devices connected to interface boards of the monitor.
Software modules dedicated to such specific devices convert the data received from an
external device to the format used internally. This applies to parameter modules and the
Anesthetic Gas Module.
- Server systems on the Philips Clinical Network
To enable networked applications such as the other bed overview, data can be acquired from
server systems attached to the Philips Clinical Network, for example a Philips Information
Center
Data Provider System Service
All data that is acquired from measurement servers or external measurement devices is
temporarily stored by a dedicated data provider system service. All monitor applications use this
central service to access the data in a consistent and synchronized way rather than talking to the
interfaces directly.
This service makes the applications independent of the actual type of data acquisition device.
The amount of data stored in the data provider system service varies for the different data types.
For example several seconds of wave forms and the full set of current numerical values are
temorarily stored in RAM.
Persistent Data Storage System Service
Some applications require storage of data over longer periods of time. They can use the
persistent data storage system service. Dependent on the application requirements, this service
can store data either in battery backed-up (buffered) memory or in flash memory. The buffered
memory will lose its contents if the monitor is without power (not connected to mains) for an
extended period of time. The flash memory does not lose its contents.
The trend application for example stores vital signs data in a combination of flash memory and
buffered memory, while the system configuration information (profiles) is kept purely in flash
memory.
20
Page 21
Monitor Theory of Operation 2 Theory of Operation
Display and User Interface Service
Applications can use high level commands to display monitoring data or status and command
windows on the internal LCD panel. These commands are interpreted by the display manager
application. This application controls the dedicated video hardware which includes video
memory and a special ASIC.
User input is acquired from a variety of input devices, for example the SpeedPoint, the
touchscreen or other standard input devices (keyboard, mouse) which may be attached to I/O
boards. The system software makes sure that the user input is directed to the application which
has the operating focus.
Data Output
The monitoring system is very flexible and customizable regarding its data output devices.
Built-in devices (for example LAN, alarm lamps, speaker, video) provide the basic output
capabilities.
These capabilities can be enhanced by adding additional I/O boards, as required in the specific
end-user setup. The additional I/O boards typically provide data to externally attached devices,
for example to printers, RS232 based data collection devices, nurse call systems etc.
The monitor can identify I/O boards by means of a serial EEPROM device that stores type and
version information. The operating system detects the I/O boards and automatically connects
them with the associated (interface driver) application. For some multi-purpose cards it is
necessary to configure the card for a particular purpose first (for example the dual MIB/RS232
card can support external touch display , data import, data export).
Monitor Applications
The monitor applications provide additional system functionality over the basic measurement
and monitoring capabilities. This includes for example trending, report generating, event storage
or derived measurements.
In general, the monitor applications use the data provider system service to access the
measurement data. Application interfaces to the other system services allow the application to
visualize data, to store data over extended periods of time or to output data to other devices.
21
Page 22
2 Theory of Operation Monitor Theory of Operation
Internal LAN (Measurement Link)
All components of the monitoring system (including measurement servers and CPUs in the
monitor) communicate using an IEEE802.3/ Ethernet LAN in the Measurement Link (MSL).
This network is used to distribute data between the components, for example:
- Digitized patient signals including wave data, numerical data and status information
(typically from the measurement server to a display unit)
- Control data representing user interactions (typically from the display unit to a measurement
server)
- Shared data structures, for example representing patient demographical data and global
configuration items
The internal LAN allows plug and play configuration of the monitoring system. The system
automatically detects plugging or unplugging of measurement servers and configures the system
accordingly.
The components on the internal LAN are time-synchronized to keep signal data consistent in the
system. Dedicated hardware support for synchronization eliminates any latency of the network
driver software.
The integrated LAN provides deterministic bandwidth allocation/reservation mechanisms so that
the real-time characteristic of signal data and control data exchange is guaranteed. This applies
to the data flow from the measurement server to the monitor (for example measurement signal
data) and the data flow from the monitor to a measurement server (for example to feed data to a
recorder module).
Integrated communication hubs in the monitor and the FMS allow flexible cabling options (star
topology, daisy chaining of servers).
22
Page 23
Monitor Theory of Operation 2 Theory of Operation
Philips Clinical Network
The monitoring system may be connected to the Philips Clinical Network, for example to
provide central monitoring capabilities or other network services. This connection may be
through a normal wired connection or through a wireless connection.
The monitor supports the connection of an external wireless adapter or an internal wireless
adapter (#J35). Switching between wired and wireless networks is automatically triggered by the
plugging or unplugging of the network cable.
The Philips Clinical Network protocols function very similarly to the protocols used on the
internal LAN.
After configuration, the monitoring system sends the digitized patient signals including wave
data, numerical data and status information onto the network. Control data representing user
interactions can be exchanged between the monitoring system and a central station
bi-directionally.
Additional protocols are supported for networked applications, for example for the other bed
overview function, which allows viewing of monitoring data from other patients on the network.
For plug and play operation, the monitoring system uses the standard BootP protocol to
automatically acquire a network address.
How does the Support Tool Work with the Monitor
The support tool is a Windows application typically installed on the laptop of a customer
engineer or a biomedical engineer working in the customer’s own service department.
The purpose of the support tool is to upgrade, configure and diagnose all monitoring componen ts
(modules, measurement servers, and monitors) in the system over the network.
The service protocol developed for this purpose uses a raw access to the devices without the
need for IP addresses etc. over a standard customer network installation, so that even defective
devices can be upgraded as long as the few kBytes of initial boot code are working. The boot
code itself can also be upgraded using the same protocol.
The tool allows access to internal service information and to serial numbers. It can be remotecontrolled, for example via a dial-up connection from a response center, provided the proper
infrastructure is in place.
For details see the Instructions for Use for the Support Tool.

Functional Block Description
Services
Operating System The Operating System (OS) provides a layer of isolation
between the specific hardware implem entati on an d the
application software. The OS performs system checks and
allocates resources to ensure safe operation when the
system is first started. This includes internal self-tests on
several hardware modules and configuration checks for
validity of configuration with the operating software.
During normal operation, the OS continues to run checks
on system integrity. If error conditions are detected the
OS will halt monitoring operations and inform the
operator about the error condition.
System Services The System Services provide generic common system
services.
In particular:
They use a real-time clock component to track time. They
synchronize to network time sources and verify the
accuracy of the system time information. They are also
responsible for managing persistent user configuration
data for all Measurement Servers, Flexible Module Racks
and IntelliVue Patient Monitoring System software
modules. User configuration data is stored in a
non-volatile read/write storage device
Applications
Application Server Client The Application Server Client provides the Citrix1 thin
client functionality.
25

2 Theory of Operation Monitor Theory of Operation
Functional Block Description
Reports The Reports Service retrieves current and stored
physiological data and status data to format reports for
printing paper documentation. The following reports are
supported:
- Vital Signs Report
- Graphical Trend Report
- Event Review Report
- Event Episode Report
- ECG Report (12 Lead/Multi-Lead)
- Cardiac Output Report
- Calculations Report
(Hemodynamic/Oxygenation/Ventilation)
- Calculations Review Report
- Wedge Report
- Test Report
- Other reports (e.g. Loops, Review Applications, Drug
report)
The Reports service generates report data which can be
printed on a local or a central printer.
Record The Record Service retrieves current and stored
physiological data and status data to format a continuous
strip recording. A recording can be triggered manually by
the operator or automatically by an alarm condition. The
Record Service uses the services of the Recorder Interface
to control an M1116B Recorder in the FMS. The Record
Service can also send data to a central recorder.
26
Page 27
Monitor Theory of Operation 2 Theory of Operation
Functional Block Description
Alarm The Alarm Service contains logic that prioritizes alarm
conditions that are generated either by the Measurement
Servers, Flexible Module Rack, or by IntelliVue Patient
Monitoring System software modules. Visual alarm
signals (messages) are displayed at the top of the
IntelliVue Patient Monitoring System display and alarm
sounds are generated by a loudspeaker. Alarm conditions
may be generated when a physiological parameter
exceeds preselected alarm limits or when a physiological
parameter or any other software module reports an
inoperative status (technical alarm, for example, the ECG
leads may have fallen off the patient). The Alarm service
manages the alarm inactivation states, for example
suspension of alarms, silencing of alarms, and alarm
reminder. Alarm signals may also be configured as
latching (alarm signals are issued until they are
acknowledged by the operator, even when the alarm
condition is no longer true). The Alarm service controls
the visual alarm signals (alarm lamps).
Trend The Trend service stores the sample values of
physiological data and status data with a resolution of 12
seconds, 1 minute or 5 minutes for a period of up to 48
hours. The data is kept in battery buffered read/write
storage and flash memory devices to be preserved across
power failures. The stored data is protected via
consistency checks and checksums. When a new patient is
admitted, the trend database erases all data of the previous
patient.
HiRes The OxyCRG (Oxygen CardioRespiroGram) service
derives a high-resolution trend graph from the
Beat-to-Beat Heart Rate, SpO2 or tcpO2, and Respiration
physiological data. The OxyCRG is specialized for
neonatal applications, allowing the operator to identify
sudden drops in Heart Rate (Bradycardia) and SpO2 or
tcpO2 (Desaturations), and supporting the operator in
visualizing Apnea situations.
ADT The ADT (Admit/Discharge/Transmit) service maintains
the patient demographics information. The operator may
admit a new patient, discharge the old patient and enter or
modify the patient demographics. The ADT service also
supports the transport of a patient (trend database) with
the M3001A Multi-Measurement Module. The ADT
service controls the deletion of old patient data, the
upload of trend data from the M3001A and the switching
back of all settings to user defaults. It also synchronizes
patient information with a central station on the network.
27
Page 28
2 Theory of Operation Monitor Theory of Operation
Functional Block Description
Calc Param The Calc Param (Calculated Parameters) service accesses
current, stored and manually entered physiological data as
input to calculation formulas. With these formulas,
derived hemodynamic, oxygenation and ventilation
variables are computed. The calculation results, including
the input parameters, are stored for later review using the
Trend service.
Drug Calc The Drug Calc application aids in calculating drug
dosages for patients.
PV Loops The PV Loops application compares graphic
representations of airway waves to help detect changes in
the patient airway condition.
Interface Managers
MDSE The MDSE (Medical Data Service Element) Interface
Manager is responsible for the exchange of real-time data
between the IntelliVue Patient Monitoring System display
unit and the Measurement Servers and Flexible Module
Rack as well as between the IntelliVue Patient
Monitoring System display unit and other devices
attached to the network. MDSE establishes and maintains
a data communication link between the devices. It
provides configuration information about the remote
device to applications in the local device and it allows the
exchange of measurement data and status information
between the devices.
Printer The Printer Interface Manager provides a high level
interface to a printer. It provides means to:
- establish a connection to the printer
- transfer data to the printer
- get status of the printer
- close connection to the printer
The Printer Interface Manager also supervises the
connection to the printer and whether the printer accepts
data (for example paper out). The Printer Interface
Manager notifies the operator in such cases.

The Display and Operator Interface Manager performs the
following tasks:
- Screen presentation of real-time and stored
physiological measurement data, alarm condition data
and status information received from the MDSE
interface manager, the Alarm service or other
IntelliVue Patient Monitoring System modules
- Screen presentation of operating controls (control
windows)
- Processing of operating control commands received
from HIF Control interface. The module verifies and
interprets the received commands and forwards them
to other software modules of the IntelliVue Patient
Monitoring System display unit, Measurement
Servers or Flexible Module Rack
- Sound generation (issues audible alarm signals and
generates audible information signals, for example
QRS and SpO2 tones, operator audible feedback)
Interfaces
LAN The LAN interface implements the physical layer of IEEE
shaping, jabber, link integrity testing, reverse polarity
detection/correction, electrical isolation, and ESD
protection. Electronically separated interfaces are used for
communication to the Measurement Servers or Flexible
Module Rack and to the network.
Centronics The Centronics interface implements the standard
signaling method for bi-directional parallel peripheral
devices according to IEEE 1284-I. The interface is used
as a parallel interface to a standard printer with electrical
isolation and ESD protection.

Functional Block Description
Display Controller The Display Controller Interface consists of a video
controller chip, video RAM and the controlling software.
The Display Controller interface processes the high level
display commands (character and graphic generation,
wave drawing) and translates them into pixels, which are
written into the video RAM where the video controller
chip generates the video synchronization signals and the
pixel stream for the Color LCD Display.
HIF Control The HIF (Human Interface Control) interface scans the
Human Interface devices for operator controls (Touch
Screen, Speed Point, USB and PS/2 devices), formats the
collected data and sends it to the display and Operating
Interface.
ECG-Out Marker-In The ECG Out/Marker In interface receives the ECG
waveform directly from the ECG/Resp Arrhythmia
ST-Segment physiological algorithm via an RS-422 serial
interface and converts the digital ECG signal to an analog
ECG signal. In addition, the ECG Out controller receives
from a connected device the marker information and
forwards this data to the ECG/Resp Arrhythmia
ST-Segment physiological algorithm. The converted
analog signal is used to synchronize a connected device to
the patient’s ECG
RS-422 The serial link RS-422 interface communicates the ECG
signal to the ECG Output/Marker In of the IntelliVue
Patient Monitoring System display unit. The interface is a
serial, differential, full-duplex link. The interface is ESD
protected.
PS/2 The PS/2 interface supports the serial protocol of standard
PS/2 devices (mouse). The PS/2 serial protocol is
interpreted by the HIF Control interface.
Nurse Call The Nurse Call board contains 2 connectors. A phone
jack type connector and a multi-port connector. The
phone jack type connector has a single close-on-alarm
relay. The multi-port connector has three alarm relays
which are configurable to be open or closed on alarm. In
addition, this interface has an audible alert capability for
loss of AC power.
MIB The MIB interface allows full-duplex, short-haul
asynchronous binary communication between the monitor
and an arbitrary (medical/non-medical) device using an
eight-pin RJ45 modular connector. Switching between
MIB and RS232 protocol is possible.

3Testing and Maintenance
Introduction
This chapter provides a checklist of the testing and maintenance procedures to ensure the
performance and safety of the monitor, the Multi-Measurement Module (MMS),the MMS
Extensions and the Flexible Module Rack (FMS) associated modules.
These tests must be performed only by qualified personnel certified by the responsible
organization. Qualifications required are: training on the subject, knowledge, experience and
acquaintance with the relevant technologies, standards and local regulations. The personnel
assessing safety must be able to recognize possible consequences and risks arising from
non-conforming equipment.
3
All recurring safety and performance assurance tests must be performed under equal
environmental conditions to be comparable.
Preventive Maintenance refers specifically to the series of tests required to make sure the
measurement results are accurate. The accuracy and performance procedures are designed to be
completed as specified in the following sections or when readings are in question.
For detailed instructions on the maintenance and cleaning of the monitor and its accessories, see
Care and Cleaning, Using Batteries and Maintenance and Troubleshooting in the monitor's
Instructions for Use.

3 Testing and Maintenance Safety Tests
Safety Tests
Safety tests are comprised of the following tests performed on the monitoring system:
- protective earth resistance
- equipment leakage current
- applied part leakage current
- system test (if required)
Safety test requirements are set according to international standards, their national deviations and
specific local requirements. The safety tests detailed in this Service Guide are derived from
international standards but may not be sufficient to meet local requirements. We recommend that
you file the results of safety tests. This may help to identify a problem early particularly if the
test results deteriorate over a period of time.
Each individual piece of equipment of the monitoring system which has its own connection to
mains or which can be connected or disconnected from mains without the use of a tool must be
tested individually. The monitoring system as a whole must be tested according to the System Test (on page
69) procedure.
Accessories of the monitoring system which can affect the safety of the equipment under test or
the results of the safety test must be included in the tests and documented.

Safety Tests 3 Testing and Maintenance
Warnings, Cautions, and Safety Precautions
- These tests are well established procedures of detecting abnormalities that, if undetected,
could result in danger to either the patient or the operator.
- Disconnect the device under test from the patient before performing safety tests.
- Disconnect the device under test from mains before performing safety tests. If this is not
possible, ensure that the performance of these tests does not result in danger to the safety
analyzer operator, patients or other individuals.
- Test equipment (for example, a Safety Analyzer) is required to perform the safety tests.
Please refer to Annex C of IEC/EN 62353 for exact requirements for the measurement
equipment and for measurement circuits for protective earth resistance and leakage currents.
Refer to the documentation that accompanies the test equipment. Only certified technicians
should perform safety testing.
- The consistent use of a Safety Analyzer as a routine step in closing a repair or upgrade is
emphasized as a mandatory step to maintain user and patient safety. You can also use the
Safety Analyzer as a troubleshooting tool to detect abnormalities of line voltage and
grounding plus total current loads.
- During safety testing, mains voltage and electrical currents are applied to the device under
test. Ensure that there are no open electrical conductive parts during the performance of
these tests. Avoid that users, patients or other individuals come into contact with touch
voltage.
- For Europe and Asia/Pacific, the monitor complies with:
IEC60601-1:1988 + A1:1991 + A2:1995 = EN60601-1:1990 +A1:1993 + A2:1995
IEC60601-1-1:2000
For USA, the monitor complies with:
UL60601-1
For Canada, CAN/CSA C22.2#601.1-M90
- Local regulations supersede the testing requirements listed in this chapter.
- If a non-medical electrical device is connected to a medical electrical device, the resulting
medical electrical system must comply with IEC/EN 60601-1-1.
- Perform safety tests as described on the following pages.

Safety Test Procedures
Use the test procedures outlined here only for verifying safe installation or service of the
product. The setups used for these tests and the acceptable ranges of values are derived from
local and international standards but may not be equivalent. These tests are not a substitute for
local safety testing where it is required for an installation or a service event. If using an approved
safety tester, perform the tests in accordance with the information provided by the manufacturer
of the tester and in accordance with your local regulations, for example IEC/EN 60601-1,
UL60601-1 (US), IEC/EN 62353, and IEC/EN 60601-1-1. The safety tester should print results
as detailed in this chapter, tog ether with other data.
Please refer to Annex C of IEC/EN 62353 for requirements for the measurement equipment and
for measurement circuits for protective earth resistance and leakage currents.

Hints for Correct Performance of Safety Tests
- Perform a visual inspection on all detachable power cords used with the monitoring system
and include these in all safety test procedures.
- Connection lines such as data lines or functional earth conductors may appear to act like
protective earth connections. These may lead to incorrect measurements and need to be
considered during testing. If necessary, unplug these connections.
- Position all cables and cords in such a manner that they do not influence the safety tests.
- Measurement of insulation resistance is not required.
45
Page 46
3 Testing and Maintenance Safety Tests
Guideline for Performance of Safety Tests
Connect the detachable power cord of the device under test to the safety analyzer's test mains
port. Connect the enclosure test lead of the safety analyzer to the enclosure of the device under
test, e.g. to the equipotential connector. For testing the applied part leakage current, connect all
applied parts to the safety analyzer using the appropriate patient lead or adapter cable. For the
ECG parameter all ten ECG-leads need to be connected to the safety analyzer. If necessary, use
an adapter cable to connect all ten ECG-leads. If necessary, repeat the safety test procedure until
all available applied parts have been tested. Refer to the documentation that accompanies the
safety analyzer for further details on how to set up and perform the test.

S(4): Applied Part Leakage Current - Mains on Applied Part
NOTE
During measurement of the Applied Part Leakage Current it is possible that the measured current
can exceed the allowed limit (per IEC/EN 60601-1 or IEC/EN 62353).
This can occur when the safety tester is connected to the invasive blood pressure and
temperature connectors at the same time during the applied leakage current measurement.
The connectors for the invasive blood pressure and temperature are independently functioning
connectors.
Although there are individual connectors on the front end, internally those parameters use the
same electrical insulation interface and are hardwired to each other. This results in an electrical
short of those connectors during measurement if a test current is applied simultaneously .
Therefore this should be avoided.
Due to the combined insulation interface, it is sufficient to connect to only one parameter
interface (that is, Invasive Blood Pressure or Temperature) of the invas ive bl ood
pressure/temperature measurement block. This avoids a short and the potential of exceeding the
limit for the current.

What is a Medical Electrical System?
A medical electrical system is a combination of at least one medical electrical piece of
equipment and other electrical equipment, interconnected by functional connection or use of a
multiple portable socket-outlet.
- Devices forming a medical electrical system must comply with IEC/EN 60601-1-1.
- Any electrical device such as IT equipment that is connected to the medical electrical
equipment must comply with IEC/EN 60601-1-1 and be tested accordingly.
69
Page 70
3 Testing and Maintenance Safety Tests
General Requirements for a System
After installation or subsequent modification, a system must comply with the requirements of the
system standard IEC/EN 60601-1-1. Compliance is checked by inspection, testing or analysis, as
specified in the IEC/EN 60601-1-1 or in this book.
Medical electrical equipment must comply with the requirements of the general standard IEC/EN
60601-1, its relevant particular standards and specific national deviations. Non-medical electrical
equipment shall comply with IEC safety standards that are relevant to that equipment.
Relevant standards for some non-medical electrical equipment may have limits for equipment
leakage currents higher than required by the standard IEC/EN 60601-1-1. These higher limits are
acceptable only outside the patient environment. It is essential to reduce equipment leakage
currents to values specified in IEC 60601-1 when non-medical electrical equipment is to be used
within the patient environment.
System Example
This illustration shows a system where both the medical electrical equipment and the
non-medical electrical equipment are situated at the patient’s bedside.
70
Page 71
Safety Tests 3 Testing and Maintenance
WARNING
- Do not use additional AC mains extension cords or multiple portable socket-outlets. If a
multiple portable socket-outlet is used, the resulting system must be compliant with IEC/EN
60601-1-1. Do not place multiple socket-outlets on the floor. Do not exceed the maximum
permitted load for multiple socket-outlets used with the system. Do not plug additional
multiple socket outlets or extension cords into multiple socket outlets or extension cords
used within the medical electrical system.
- Do not connect any devices that are not supported as part of a system.
- Do not use a device in the patient vicinity if it does not comply with IEC/EN 60601-1. The
whole installation, including devices outside of the patient vicinity, must comply with
IEC/EN 60601-1-1. Any non-medical device placed and operated in the patient’s vicinity
must be powered via a separating transformer (compliant with IEC/EN 60601-1-1) that
ensures mechanical fixing of the power cords and covering of any unused power outlets.
71

System Installation Requirements
- Ensure that the the medical electrical system is installed in a way that the user achieves
optimal use.
- Make sure the user is informed about the required cleaning, adjustment, sterilization and
disinfection procedures listed in the Instructions for Use.
- The medical electrical system must be installed in such a way that the user is able to carry
out the necessary cleaning, adjustment, sterilization and disinfection procedures listed in the
Instructions for Use.
- Ensure that the medical electrical system is installed in a way that an interruption and
restoration of power to any part of the medical electrical system does not result in a safety
hazard.
- We recommend using fixed mains socket outlets to power the medical system or parts
thereof. Avoid using multiple portable socket-outlets.
- Any multiple portable socket outlets used must be compliant with IEC 60884-1 and IEC
60601-1-1.
- Ensure that any part of the system connected to multiple portable socket-outlets is only
removable with a tool, i.e. the multiple portable socket-outlet provides a locking mechanism
to prevent power cords from being plugged or unplugged unintentionally. Otherwise, the
multiple portable socket-outlet must be connected to a separation device. Multiple Socket
Outlets used within the medical electrical system must only be used for powering medical
electrical equipment which is part of the system.
- Ensure that any functional connections between parts of the medical electrical system are
isolated by a separation device according to IEC 60601-1-1 to limit increased equipment
leakage currents caused by current flow through the signal connections. This only works if
the equipment leakage current of the respective medical electrical system parts is not
exceeded under normal conditions.
- Avoid increase of equipment leakage currents when non-medical electrical equipment within
the medical electrical system is used. This only works if the equipment leakage current of
the respective medical electrical system parts is not exceeded under normal conditions. Use
additional protective earth connection, separation device or additional non-conductive
enclosures.
- Within the patient environment it is important to limit electrical potential differences
between different parts of a system. If necessary, use potential equalization equipment
(equipotential cable) or additional protective earth connections.
- Medical electrical equipment used in medical rooms must be connected to potential
equalization equipment (equipotential cable) to avoid electrical potential differences. Check
your local requirements for details.

System Test Procedure
If the medical electrical device has already been tested as a standalone device e.g. during factory
safety testing, an equipment leakage current test must only be performed once the device is
connected to the LAN network. If the medical electrical system has not been tested as a
standalone device, the device has to be tested as a standalone device (without connection to the
system) and as part of the system (with connection to the system).
Connect the detachable power cord of the device under test to the safety analyzer's test mains
port. Connect the enclosure test lead of the safety analyzer to the enclosure of the device under
test, e.g. to the equipotential connector. Refer to the documentation that accompanies the safety
analyzer for further details on how to set up the test.

1. Check that the 5% calibration gas and flow regulator are connected.
2. Calculate the expected measurement value in mmHg as follows:
0.05 x (ambient pressure) = value mmHg
for example 0.05 x 736 = 36.8 mmHg (with an ambient pressure of 736 mmHg)
3. Open the valve on the flow regul ator to allow 5% CO

6. Calculate the expected measurement value and tolerance in mmHg as follows:
0.1 x (ambient pressure) = value mmHg
±0.07 x (value mmHg) = tolerance
for example 0.1 x 737 mmHg = 73.7 mmHg (with an ambient pressure of 737 mmHg)
±0.07 x 73.7 mmHg = ±5.16 mmHg tolerance

8. Check that the value on the instrument (x8) matches the calculated mmHg value within the
calculated tolerance. If so, the measurement extension is correctly calibrated. If the value is
outside the tolerance, calibrate as follows.

12. Open the valve on the calibration gas to allow CO2 gas to flow into the extension. Allow the
value to stabilize before the start of the calibration. Leave the valve open until the instrument
gives a prompt that gas can be removed.
13. The extension calibrates and prompts when calibration is successful.
Calibration Verification
1. Reopen the 5% gas valve and allow the value to stabilize.
2. Check that the value displayed on the monitor is correct within the tolerance (see step
above).
3. Disconnect the 5% calibration gas and connect the 10% calibration gas.
4. Open the valve on the flow regulator to allow 10% CO2 gas to flow into the extension.
Allow the value to stabilize.
5. Check that the value displayed on the monitor is correct within the tolerance (see step
above).
If one or both values are not within tolerances, you must exchange the M3015A MMS Extension
