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.
