1.0 Introduction
The MATRIX instrument allows verification/certification personnel to evaluate Medical Air Systems as well as system designated
piping applications for O2, N2, CO2 and N2O levels. The instrument is available with up to 8 internal sensors. Available sensors
include, but are not limited to, anesthesia gases, carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2), methane (CH4), nitrous
oxide (N2O) trace Hydrocarbons (HC), and for dew point. The sensors can be used alone or up to four sensors can be used together
on each of the two main circuit boards inside the MATRIX. In the instrument, the gas sample is passed over each sensor and the
resulting electrical outputs are used to evaluate the air for the target gases.
Some features of the instruments are as follows:
 LCD display of gas and vapor concentrations
 visual alarms indicate target gas levels
 low air flow fault indication and display
 alarm acknowledgement

3.0 Air and Power Supply
3.1 Sample Air Supply
Sampling of target gases is accomplished by either connecting the MATRIX unit to a compressed air/gas line or for ambient air
monitoring by a sampling system (sampling pump) capable of flowing a air/gas sample through the sensor manifold associated
with Side A or Side B of the MATRIX. Due to the variations of sampling connection possibilities the MATRIX unit is only
supplied with the proper connection(s) to the MATRIX unit.
Dew Point: Connect the supplied sampling hose to the compressed air line and MATRIX unit. Set the inlet pressure to 55±5 PSIG.
For inputs A, B and N2O connect the supplied sampling hose and adjust the flow rate to 0.5 lpm (1 SCFH).
For all sensors except dew point do not exceed flow rate of 1 lpm. Flow rates should be kept constant during all gas/vapor
measurements.
3.2 Power Supply
The MATRIX is powered by a 15.2 VDC rechargeable Lithium Ion battery. The battery is recharged by an internal battery
charging circuitry that is powered through the 110 VAC socket on the side of the enclosure. A 110 VAC line cord is supplied with
the MATRIX.
CAUTION: The Lithium Ion battery cannot be substituted. Replacing the Lithium Ion battery with other power sources will cause
damage to the MATRIX unit.
Status of the Lithium Ion battery is indicated by an LED located at the top center of the display panel.
 LED Not lit, Instrument is off or 110 VAC line cord is not connected.
 LED Green and Steady, the battery is charged.
 LED Green and Blinking, the battery is charging.
 LED Red Blinking, indicates a power supply problem, contact ENMET.
NOTE: Federal regulation require that an approved “Lithium handling label” be attached to outer surface of the shipping
package before tendering for shipment via commercial carriers.
3.2.1 Circuit Protection, Fuse:
The power supply system is protected by a 5.0Amp Slo-Blo fuse located on the front panel of the MATRIX.
CAUTION: The Fuse, 5.0Amp Slo-Blo protection of the electronic circuitry, must be removed from the MATRIX prior to
offering the MATRIX unit for shipment through commercial carriers.
NOTE: The fuse holder on top left of the Matrix Monitor must have the proper fuse inserted and the fixture rotated to lock the
fuse into the charging circuit. The below comments apply only when fuse is properly inserted.
[If the fuse is defective or not installed and the power cord is connected to a 120Vac, the charger light flashes yellow/red/green.
After a few seconds the Matrix shuts off side A and side B completely.]

CAUTION: CO2 Information for Matrix Users
Ambient air (Fresh Air) levels of CO2 can be 350 to 400 part per million (ppm) in most parts of the planet. Human respiration,
industrial processes and winter heating equipment can lead to indoor air quality CO2 levels in the 550 to 1500 ppm in many
locations. Even well-maintained air compressors can yield over 500 to 600 ppm CO2 in compressed air streams. As a result of the
above, your Matrix unit can easily have over 500 ppm CO2 trapped in its internal pneumatics and sensor housing. You may
require 15 to 30 minutes of flow of a CO2 free gas stream to “purge” this trapped CO2 from your Matrix instrument prior to some
critical measurements.

4.3 Alarms
Alarm set points can be changed within limits; see the maintenance section of this manual for the procedure.
 Channels containing CH4, CO HC, BRH, CO2 and DP are configured to have alarm points that activate as the detected
concentration of gas increases.
 The Oxygen channel is configured to have alarm activation when the oxygen concentration is depleted.
 The N2O channel is configured to be in alarm anytime the concentration is below 90% by volume.
4.4 Audio Defeat
The MATRIX instrument is not provided with an audio alarm making the audio defeat portion of the switch non-operable. The
alarm acknowledge is in effect, and is used to clear the alarm LED indicator following a gas level detection.
4.5 Display
In clean air an example of a display is shown in Figure 3. This position of the display is termed the "operational display". As
explained below, the display can be used to view other information by using the OPTION and SELECT switches.
Examples, concentrations of CO and CO2 are given in PPM (parts per million parts of air). Dew point is given in degrees
Fahrenheit at 55 PSIG; this can be changed to degrees Centigrade by pressing the SELECT switch. Oxygen concentration is given
in percent by volume.
When sample flow is reduced below a limit, the bottom line of the display flashes “Low Flow Alarm”.

4.7 Fault Indications
4.7.1 Low Flow Indication
A flow sensor is used to furnish a low flow indication. When the sample air pressure drops below approximately 0.3 LPM, the
fault light and audio alarm are activated, and the display flashes “Low Flow Alarm”.
4.7.2 Other Fault Indications
Other fault indications are associated with sensor zero and calibration activities, and are described in the maintenance Section
5.0 of this manual.
4.8 Dew Point Sensor Response
It is a characteristic of the MATRIX that it takes more time to extract moisture from a sample by passing dry air through it, than it
does to add moisture to a sample by passing moist air through it. Therefore, the time response of the instrument to a step change
from moist to dry air is slower, then the response to a step change from dry to moist air.
It is the nature of most materials to absorb and release moisture at different rates. In general, it typically takes longer for a system
to establish moisture equilibrium when going form a high to low humidity than it does to go from low to high. The MATRIX is no
different. The sensor T90 response time is 10 seconds for a –40° to +50°F step change and 240 seconds for a +50° to –40°F step
change. The delivery apparatus such as regulators, piping and tubing account for the additional response time of the instrument as
a system.
4.9 Hydrocarbon Sensor Response
If a Hydrocarbon (HC) sensor is supplied with the MATRIX instrument, it operates by the photo-ionization principle (PID) and it
designed to detect hydrocarbon gases and vapors with an ionization potential (IP) of 10.6 eV or less. Hydrocarbons with an IP of
greater than 10.6 eV will NOT be detected. Please see Appendix A for a list of common gases and vapors and their respective IP
rating.
Unless otherwise noted Isobutylene is used as a calibration and reference gas for their PID sensor.

5.4 Sensor Replacement
The MATRIX requires periodic sensor calibration and replacement. Due to the complexity of the MATRIX unit ENMET does not
recommend field calibration of the instrument with the exception of the oxygen channel. Oxygen, Dew Point and CO sensors have
an estimated lifetime of 1 – 2 years. The HC, BRH, N2O and CO2 sensor has an estimated lifetime of 3 years.
Sensor life and response can be tracked by ENMET when the MATRIX Calibration Program is utilized. Sensor replacement is an,
as needed, situation. Cost would be per sensor replacement and is in addition to the MATRIX calibration Program fee.

Appendix C: ISEA Statement
ISEA Statement on Validation of Operation for Direct Reading Portable Gas Monitors
The International Safety Equipment Association (ISEA) is the leading national organization of manufacturers of safety and health
equipment including environmental monitoring instruments. ISEA is dedicated to protecting the health and safety of all workers
through the development of workplace standards and the education of users on safe work practices and exposure prevention.
ISEA has developed this statement to ensure definition consistency in all documentation, and to emphasize the need to validate the
operational capability of portable gas monitors. The statement reflects current instrumentation technologies and monitoring practices.
Specifically, the statement intends to:
a. Define and clarify the differences between bump test (function check), calibration check, and full calibration;
b. Clarify when these validation methods are to be performed; and
c. Reemphasize to users, regulatory agencies and standards writing bodies the importance of validating the operational capabilities
of portable gas monitors used to examine the atmosphere in potentially hazardous locations.
1. Definitions
a. Bump Test (Function Check) - A qualitative function check where a challenge gas is passed over the sensor(s) at a
concentration and exposure time sufficient to activate all alarm indicators to present at least their lower alarm setting. The
purpose of this check is to confirm that gas can get to the sensor(s) and that all the alarms present are functional. This is
typically dependent on the response time of the sensor(s) or a minimum level of response achieved, such as 80% of gas
concentration applied. Note this check is not intended to provide a measure of calibration accuracy.
b. Calibration Check - A quantitative test utilizing a known traceable concentration of test gas to demonstrate that the sensor(s)
and alarms respond to the gas within manufacturer’s acceptable limits. This is typically ±10-20% of the test gas concentration
applied unless otherwise specified by the manufacturer, internal company policy, or a regulatory agency.
c. Full calibration – The adjustment of the sensor(s) response to match the desired value compared to a known traceable
concentration of test gas. This should be done in accordance with the manufacturer's instructions.
2. Recommended Frequency
a. A bump test (function check) or calibration check of portable gas monitors should be conducted before each day’s use in
accordance with the manufacturer’s instructions.
Any portable gas monitor which fails a bump test (function check) or calibration check must be adjusted by means of a full
calibration procedure before further use, or removed from service.
b. A full calibration should be conducted at regular intervals in accordance with instructions specified by the instrument’s
manufacturer, internal company policy, or a regulatory agency.
c. Validation of an instrument’s operability should be conducted if any of the following conditions or events occurs during use:
i. Chronic exposures to, and use in, extreme environmental conditions, such as high/low temperature and humidity, and high
levels of airborne particulates.
ii. Exposure to high (over range) concentrations of the target gases and vapors.
iii. Chronic or acute exposure of catalytic hot-bead LEL sensors to poisons and inhibitors. These include volatile silicones,
hydride gases, halogenated hydrocarbons, and sulfide gases.
iv. Chronic or acute exposure of electrochemical toxic gas sensors to solvent vapors and highly corrosive gases.
v. Harsh storage and operating conditions, such as when a portable gas monitor is dropped onto a hard surface or submerged in
liquid. Normal handling/jostling of the monitors can create enough vibration or shock over time to affect electronic
components and circuitry.
vi. Change in custody of the monitor.
vii. Change in work conditions that might have an adverse effect on sensors.
viii. Any other conditions that would potentially affect the performance of the monitor.
