Operation Guide
Warnings and Cautionary Statements
IMPORTANT: Failure to perform certain procedures or note certain
conditions may impair the performance of this product. For maximum
safety and optimal performance, please read and follow the procedures
and conditions listed below.
IMPORTANT: Read and understand this manual before
operating.
AVERTISSEMENT: Lire attentivement les instructions avant de
mettre en marche.
WARNING: SERVICING THE UNIT, REPLACING THE
RECHARGEABLE BATTERY PACK, OR CHANGING THE
ALKALINE BATTERIES MUST ONLY BE DONE IN AN AREA
KNOWN TO BE NONHAZARDOUS.
WARNING: INSERT THE ALKALINE BATTERIES WITH THE
CORRECT POSITIVE “+” AND NEGATIVE “-“ ORIENTATION.
FAILURE TO FOLLOW PROPER BATTERY ORIENTATION
WILL RESULT IN DAMAGE TO THE INSTRUMENT.
WARNING: THE MX4 IS ONLY APPROVED FOR USE WITH
AAA BATTERY TYPES ENERGIZER EN92 AND DURACELL
MN2400. DO NOT MIX BATTERY TYPES.
A functional bump test of the instrument should be performed
before each day’s use. If the instrument does not pass the bump
test, a full instrument calibration should be performed prior to
use.
The MX4 is CSA certified according to the Canadian Electrical
Code for use in Class I, Division 1 and Class I, Zone 1
Hazardous Locations within an ambient temperature range of
Tamb: -20°C to +50°C. CSA has assessed only the %LEL
combustible gas detection portion of this instrument for
performance according to CSA Standard C22.2 No. 152,
applicable only when the instrument is used in the diffusion
mode and has been calibrated to 50% LEL CH4.
Oxygen deficient atmospheres may cause combustible gas
readings to be lower than actual concentrations.
Oxygen enriched atmospheres may cause combustible gas
readings to be higher than actual concentrations.
Operation Guide
Rev 2.0 (p/n: 17140724) INDUSTRIAL SCIENTIFIC 5
Verify the calibration of the combustible gas sensor after any
incident where the combustible gas content has caused the
instrument to display an over-range condition.
Silicone compound vapors or other known contaminants may
affect the combustible gas sensor and cause readings of
combustible gas to be lower than actual gas concentrations. If
the instrument has been used in an area where silicone vapors
were present, always calibrate the instrument before next use to
ensure accurate measurements.
Sensor openings and water barriers must be kept clean.
Obstruction of the sensor openings and/or contamination of the
water barriers may cause readings to be lower than actual gas
concentrations.
Sudden changes in atmospheric pressure may cause temporary
fluctuations in the oxygen reading.
Charge battery, service unit, and use its communication port
only in non-hazardous locations. Not for use in oxygen-enriched
atmospheres.
WARNING: Substitution of components may impair intrinsic
safety and may cause an unsafe condition.
AVERTISSEMENT: La substitution de composants peut
compomettre la securite intrinseque.
CAUTION: For safety reasons, this equipment must be operated
and serviced by qualified personnel only. Read and understand
the instruction manual completely before operating or servicing.
ATTENTION: Pour des raisons de sécurité, cet équipment doit
étre utilesé entretenu et réparé uniquement par un personnel
qualifié. Étudier le manuel d'instructions en entier avant d'utiliser,
d'entretenir ou de réparer l'équipement.
CAUTION: High off-scale readings may indicate explosive
concentration.
ATTENTION: Des lectrures supérieures a l'échelle peuvent
indiquer des concentrations explosives.
Operation Guide
6 INDUSTRIAL SCIENTIFIC Rev 2.0 (p/n: 17140724)
CAUTION: Any rapid up-scale reading followed by a declining or
erratic reading may indicate a gas concentration beyond the
upper scale limit which may be hazardous.
CAUTION: CSA C22.2 No. 152 requires before each day’s
usage, sensitivity must be tested on a known concentration of
pentane or methane equivalent to 25% or 50% of full scale
concentration. Accuracy must be within -0% to +20% of actual
concentration. Accuracy may be corrected by referring to the
zero/calibration section of the instruction manual.
The model MX4 complies with relevant provisions of European
ATEX directive 94/9/EC and EMC directive 89/336/EEC,
amended by directives 92/31/EEC and 93/68/EEC.
The EC type examination certificate is DEMKO 09 ATEX
0854530 ; with marking code Ex ia d I/IIC T4; for equipment
group and category II 2G and I M2.
The MX4 iQuad Multi-Gas Monitor is constructed with reference
to published standards of directive 72/23/EEC, to eliminate
electrical risks and fulfill 1.2.7 of ANNEX II of directive 94/9/EC.
Contact your service representative immediately if you suspect
that the MX4 is working abnormally.
Specifications subject to change without notice.

Introduction
The MX4 is a light-weight, portable gas monitor capable of continuously
and simultaneously monitoring 4 gases:
Oxygen (O2)
Combustible (LEL and CH4)
Two interchangeable toxics (CO, H2S, NO2)
The sensors are easily replaced. Gas readings from the installed sensors
are displayed on a custom graphic LCD. Peak readings are also available
for each sensor, and can be cleared by the user.
The instrument provides alarms for the following conditions:
low limit (user adjustable)
high limit (user adjustable)
STEL (user adjustable)
TWA (user adjustable)
overdue for calibration (user selectable).
Overdue for bump test (user selectable)
When alarm conditions are exceeded, the MX4 has an audible, visual and
standard vibrating alarm to alert the user.
The MX4 is compatible with the MX•Cal™ calibration station, the DS2
Docking Station™, and its own cradle-style charger. It communicates to
the Charger/Datalink via infrared communications (IrDA). MX4 is also
compatible with Industrial Scientific’s automated and comprehensive gas
monitor management solution, iNet™.
The MX4 performs continuous data logging at 10 second intervals and
can hold approximately three month’s of data for the four-sensor
configuration. Readings are time-stamped and are stored in a first-in-first-
out (FIFO) queue that is overwritten when full. In addition to data logging,
the MX4 has an event log that records the last 15 alarm events.

Turning the MX4 ON and OFF
To turn on the MX4, press and hold the On/Off/Mode button ( ) until the
unit emits a single beep (approximately 3 seconds). All icons and
segments on the LCD display as shown in the graphic above. Next, the
software version is displayed. After this, the instrument performs a 20
second countdown, during which the user has the option to enter the
configuration mode (by pressing and holding both the On/Off/Mode ( )
and Enter ( ) buttons simultaneously). If this configuration mode option is
bypassed, the MX4 enters the normal operating mode and displays the
normal monitoring screen. Sequential presses of the On/Off/Mode button
will cycle the user through the Days Since Calibration Screen, Zero
Screen (if enabled), Peak Readings Screen, Time Weighted Average
(TWA) Screen (if toxic sensors are installed) and the Short Term
Exposure Limit (STEL) Screen (if toxic sensors are installed). Another
press of the On/Off/Mode button returns the user to the normal monitoring
screen. Each screen is explained individually in the sections that follow.
To turn off the MX4, press and hold the
On/Off/Mode button for 5 seconds. During
the shutdown process, the displayed value
will change from “5” to “1” and the MX4 will
beep five times.
NOTE: Any button press activates the backlight for a period of 30 seconds.
