every transaction, every time

Dear Valued Customer,

Thank you for buying and using Industrial Scientific’s
iTX Multi-Gas Monitor.

Your iTX can be relied upon for dependable service, day
after day. It has been designed, manufactured, tested and
proven under the most scrutinizing conditions possible.
With the minimal care and maintenance described in this
Instruction Manual, it will provide you with years of
reliable monitoring.

I am most concerned that you be pleased with the
performance of your iTX in the months and years ahead.
I urge you to call us with any questions or comments you
may have. Often times a phone call and a question can
save you hours of frustration. Please never hesitate to
contact me at 1-800-DETECTS (338-3287).

All of us at Industrial Scientific appreciate the opportunity
to serve you.

Sincerely,

Kent D. McElhattan
Chairman

ARNINGS ANDCAUTIONARYSTATEMENTS

Failure to perform certain procedures or note certain conditions may
impair the performance of the instrument. For maximum safety and
performance, please read and follow the procedures and conditions
outlined below.

Oxygen deficient atmospheres may cause combustible gas readings to

be lower than actual concentrations.

Oxygen enriched atmospheres may cause combustible gas reading to

be higher than actual concentrations.

Verify the calibration of the combustible gas sensor after any incident
where the combustible gas content has caused the instrument to latch in
the OVER-RANGE alarm 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.

Recharge battery only in a non-hazardous location.

Instrument is tested for intrinsic safety in explosive gas/air (21%

oxygen) mixtures only.

CAUTION: High Over-Range (+OR) combustible gas readings may
indicate an explosive concentration of combustible gas. This condition
locks the iTX in high alarm and must be manually reset by clearing the
gas hazard and turning the iTX off and on again.

iTX units equipped with bias sensors will self discharge a fully charged
battery in approximately four days. Because of this, bias sensor equipped
units are shipped without the battery installed. Upon receipt, install the
battery and allow the bias sensors to stabilize for 24 hours. Always store
bias sensor equipped iTX units on the appropriate charger (lithium-ion
versions only).

The use of leather cases can produce inaccurate readings with diffusion
(non-aspirated) gas detection instruments for specific monitoring applications.
Leather cases should be used ONLY as carrying cases, and NOT for
continuous monitoring, with diffusion instruments configured to measure
gases other than O2, CO, CO2, H2S, and combustible gases (LEL/CH4).

PERATION

TURNING THE iTX ON AND OFF

To turn the iTX on, press and hold until the
instrument emits a short beep and the iTX welcome screen
appears on the display. The current revision of instrument
operating software is shown below the instrument model
name.

Revision 1.0

After the iTX warm-up screen, the display will identify
any new sensors installed which have not been calibrated
in the instrument. If this screen appears, the instrument
must be calibrated prior to further use. If the system clock
has not been set, you will be prompted to do so.

Prior to entering the normal operating mode, the iTX
display will show the type of each sensor installed in the
instrument along with a brief countdown timer until
normal gas readings appear.

To turn the iTX off, press and hold at any time
during operation until the instrument display shows
RELEASE. After releasing the instrument’s display
will blank and all operation will cease.

GAS READING MODE

In the Gas Reading Mode the iTX will show the type of
each sensor currently installed with the corresponding gas
concentration shown directly underneath it. A battery
status indicator is shown in the center of the display. As
the instrument battery life is reduced, the shaded area of
the battery indicator will clear until the instrument reaches
the low battery condition. With 15 minutes of battery life
left, a low battery condition occurs. The instrument will
make a periodic tone alerting the user that the battery
needs charged or replaced. If a preset gas alarm level is
exceeded for either low, high, STEL or TWA, the iTX will
activate audible and visual alarms and the corresponding
gas display will flash.

PPM EXPLOSIVE GAS READING

If the ppm explosive feature is enabled, press until
“PPM EXP” appears. This screen will display the current
concentration of explosive gas in parts per million (ppm)
in 50 ppm intervals up to 10,000 ppm. If any gas reading
increases to a level exceeding the low alarm set-points, the
instrument will automatically return to the gas reading
mode.

have been enabled. While scrolling through the modes of
operation, pressing the when prompted access the
desired functions. To add or remove items from the
operating modes, the user must enable/disable the features
through the iTX configuration settings. Accessing these
custom settings is described in the Configuring iTX’s
Custom Section on page 11.

Zero Sensors

Press E to Zero

ZEROING AND CALIBRATION

If the zero and calibrate feature is enabled, press
until “Zero Sensors” appears. Pressing while this
screen is displayed will activate the instrument’s 20
second ZEROING sequence. This resets the current
instrument reading and reference point to zero and
calibrates the oxygen sensor to 20.9% in ambient air.
After the zeroing sequence is complete, pressing will
allow you to perform a span calibration to adjust and
ensure the accuracy of the instrument, see Calibrating the
iTX, page 21.
