WARNINGS AND CAUTIONS
WARNINGS
A WARNING indicates that there is a possibility of injury to
yourself or others.
PROPER GROUNDING: For protection against shock hazards,
connect this monitor only to a three-wire, grounded, hospital grade
receptacle. Do NOT remove the grounding prong from the power
plug. Do NOT use extension cords or adapters of any type. The
power cord and plug must be intact and undamaged. Should the
power cord or plug become cracked, frayed, broken or otherwise
damaged, it must be replaced. When connecting an external AC-
operated equipment to the monitor, make sure that the equipment
is properly grounded.
Do NOT perform any testing or maintenance on medical
instruments while they are being used to monitor a patient.
Monitor models not including the automatic agent identification
cannot distinguish between anaesthetic agents. Manufacturer
assumes no liability for an incorrect anaesthetic selection.
When doing any work on the SpO2board care has to be taken that
the patient isolation is not violated.
EXPLOSION HAZARD: Never use this monitor in the presence of
flammable anaesthetics.
FUSE REPLACEMENT: For continued protection against fire
hazard, replace only with the same type and rating of fuse.
Do not make any modifications to the patient cables without
consulting the manufacturer.
ELECTRIC SHOCK HAZARDS:
The CRT display unit contains high voltage circuitry.
In case of mechanical damage, carefully inspect the integrity of the
patient isolation circuitry, CRT unit high voltage circuitry, the
power supply transformer and primary wiring.
Do NOT immerse the monitor or probe in any liquid. An SpO2
probe that is damaged or has been immersed may cause burns
during electrosurgery.
Switch the power off and unplug the power cord before cleaning
or service.
January 15th, 1997/6

CAPNOMAC ULTIMA TM SERVICE MANUAL
2-2
Do NOT touch any exposed wiring or conductive surface while the
cover is off and the monitor is energized. The voltages present
when the electric power is connected to the monitor can cause
injury or death.
After doing any repair or calibration procedure to the monitor,
perform a final electrical safety check and current leakage test.
The manufacturer accepts no responsibility for any modifications
made to the monitor outside the factory.
CAUTIONS
A CAUTION indicates a condition that may lead to equipment
damage or malfunction.
The tests and repairs described in this manual should only be done
by trained personnel with proper tools and test equipment.
Unauthorized service may void the monitor warranty.
Check the rear panel voltage setting before connecting the monitor
to AC mains power outlet.
When the monitor is in use, leave space for ventilation to minimize
heat accumulation inside the monitor.
Connect sample gas outlet on the monitor’s rear panel to
scavenging system to prevent room air pollution. Diameter of
scavenging system tubing must be 2 to 3 times larger than that of
sample out tubing to avoid changing the operating pressure of the
monitor and consequent inaccurate readings or internal damage.
Diameter of calibration gas delivery tube must be 2 to 3 times
larger than that of the sampling line to avoid overpressurization
and consequent inaccurate calibration or internal damage of the
monitor.
After performing any service always check the oxygen transducer
by breathing into the sampling line and observing 02waveform
display. After a moment’s delay the wave should drop from the
room air (21 %) to between 13 and 17 % 02. The oxygen
transducer uses room air as reference gas. It is possible for the
transducer to malfunction or for the connecting tubing to be
disconnected, and the digital display read 21 % 02.
Before use, allow two minutes for warm-up and note any error
messages or deviations from normal operation.
January 15th, 1997/6

CAPNOMAC ULTIMA TM SERVICE MANUAL 2-3
Always switch the monitor off before making any connections with
external equipment.
Avoid ammonia-, phenol-, or acetone-based cleaners for they may
damage the monitor’s surface.
Electrostatic discharge through the pc boards may damage the
components of the monitor. Handle all pc boards by their non-
conductive edges and use anti-static containers when transporting
them. Before replacing and repairing pc boards, wear a static
control wrist strap to discharge any accumulated static charge.
Do not disassemble the ACX measuring unit. The unit is repaired
and adjusted at the factory.
When removing or inserting any part into the monitor, be careful
not to kink or damage the gas sample tubes. Leakages in the gas
sampling system affect accuracy of measurement and are difficult
to detect.
When servicing the sampling system, make sure not to leave any
tubes touching the sampling pump. Abrasion may damage the
tubes.
Do not apply tension to the power cord.
Do not autoclave the monitor nor probes.
Do not gas sterilize the monitor.

INTRODUCTION AND APPLICABILITY OF THIS MANUAL
3.1
Introduction and applicability of this manual
This service manual (Doc. No. 878131) and the Panasonic CRT
Data Display Model M-K9l0lNB service manual (available from
DATEX-ENGSTROM Division, order code 572760) provide
information required to maintain and repair the CAPNOMAC
ULTIMATM ULT- l/ULT-S/ULT-V/ULT-SV/ULT-i/ULT-
Si/ULT-Vi/ULT-SVi model monitors. This manual is applicable
for the current production revision of the monitors. Differences
between monitor revisions are summarized in Section 3.2 and the
technical details of earlier revisions given in Chapter 11. Section
3.3 lists the technical (hardware) changes made to the monitor and
Section 3.4 the software changes.
The revision of a monitor is changed when technical changes are
made to the monitor resulting in new spare parts that are
incompatible with earlier units. The last two digits of the monitor
type designation denote the revision of the monitor (e.g. ULT-l-
23-00 is a revision -00 unit).
Functional units of the monitor (pc boards) will have ID code
stickers indicating the modification level of the production
documentation. The code is shown as xxxxxx-y, where the “xx...”
represents the part number and “y” the revision level, which is
referred to when hardware changes are indicated in this manual.
The following list shows the models and their monitoring
parameters.

This manual describes all the functions offered by the
CAPNOMAC ULTIMATM monitor. Some of the functions may not
be available in the monitor you are using.
ACX-200 Measuring board measures sevoflurane and desflurane in
addition to halothane, isoflurane, and enflurane. The difference
between the ACX-200 Measuring board and ACX-100 Measuring
board is that the former contains several precision resistors. The
ACX-200 Measuring board can simply be used to replace the
ACX-100 Measuring board but not vice versa. Unless otherwise
noted, the description of ACX-100 Measuring bench/board is also
valid to ACX-200 Measuring bench/board.
ASX-100 identifies halothane, isoflurane, and enflurane. ASX-200
identifies halothane, isoflurane, enflurane, sevoflurane, and
desflurane.
If ASX-100 is replaced by ASX-200 (or i-kit which includes
ASX-200 is installed in the monitor), ACX must be upgraded to
ACX-200 and the main software replaced (the i-kit includes the
main software).
Please review the Operator’s Manual to obtain a clear
understanding of the monitor.
The manufacturer reserves the right to make changes in product
specifications at any time and without prior notice. The
information in this document is believed to be accurate and
reliable; however the manufacturer assumes no responsibility for its
use.
