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).

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.

ALIBRATING THE

iTX

Gas detection instruments are potential life-saving

devices. Recognizing this fact, Industrial Scientific

Corporation recommends that a functional (“bump”) test

be performed on every instrument prior to each days use.

A functional test is defined as a brief exposure of the

monitor to a concentration of gas(es) in excess of the

lowest alarm set-point for each sensor for the purpose of

verifying sensor and alarm operation and is not intended

to be a measure of the accuracy of the instrument.

Industrial Scientific further recommends that a full

instrument calibration be performed using a certified

concentration(s) of Industrial Scientific branded

calibration gas(es) monthly to ensure maximum

accuracy. Use of calibration gases from manufacturers

other than Industrial Scientific may void product

warranties and limit liability claims against the

manufacturer.

If an instrument fails to operate properly following any

functional “bump” test, a full instrument calibration

should be performed prior to use.

STANDARD CALIBRATION

To calibrate the iTX, press until “Zero Sensors” appears. Press to begin the zeroing process. All toxic and combustible sensors will be reset to zero during this procedure. Once these sensors have properly zeroed, the oxygen sensor calibration screen will appear. This screen will display “O2 CAL” along with the current full span reading for the oxygen sensor. The full span value reveals how much life remains in the gas sensor. Interpretation of the full span value will be explained at the completion of this section of this manual.

When the zeroing process is complete the instrument will beep and the “Zeroing Complete; E to Continue” screen will appear. Press and select calibration. Select “Yes” then press to begin the instrument span calibration. The display will show the first sensor to be calibrated along with the calibration gas concentration and the message “Apply Cal Gas.” At this point, apply the sample of a known concentration of the appropriate calibration gas at a flow rate of .5 LPM (1 SCFH) to the iTX as shown. The iTX will automatically recognize the presence of the calibration gas and display “Cal in Process” along with the current full span value of the sensor. The instrument will be calibrated automatically when the sensor response to the calibration gas becomes stable.

After each sensor has been calibrated, the instrument will beep and the display will step to the next sensor to be calibrated. The steps will be repeated automatically until each sensor has been calibrated. To skip a sensor, press

when the appropriate gas is displayed. A summary of full span values appears on the display at the completion of the calibration sequence.

QUICK CALIBRATION

If the Quick Cal feature of the iTX has been enabled, all sensors capable of being calibrated using a multicomponent cylinder will be adjusted simultaneously. If a sensor is installed in the instrument which cannot be calibrated using the Quick Cal feature, the instrument display will automatically step to that sensor prior to starting the Quick Cal. This will save time as well as the amount of gas used during calibration and eliminate the repetition of the steps described above.

When the calibration process has been completed the instrument will show the calibration status display. This screen will show each sensor type along with the full span value determined during the calibration and the result of the calibration as PASS, MARGinal or FAIL. Any sensor with a full span value greater than 70% of the calibration gas value will show PASS. Full span values between 50 and 70 percent of the calibration gas value will allow the sensors to calibrate successfully but will be considered MARGinal calibrations. Marginal calibrations indicate that sensor may soon need to be replaced. Full span values less than 50% of the current calibration gas value will FAIL calibration. Sensors which fail calibration should be replaced immediately.

EMOTESAMPLING

USING THE iSP (MOTORIZED SAMPLING PUMP)

By itself, the iTX is a diffusion gas monitor capable of monitoring the ambient air. When combined with the iSP motorized sampling pump, the iTX can now be used to evaluate an atmosphere up to 100 feet away.

FAULT

POWER

PPM PPMPPM

PPMLEL/CH4%VOL

The iSP is a parasitic sampling pump, meaning it operates without a dedicated battery and draws its power from the iTX itself. To use the iSP, simply slide it over the top end of the iTX. With the iTX turned on and the iSP fully engaged, you will hear a short audible beep and the pump motor will begin to run.

Verification of the flow alarm is recommended before each day's use. To verify operation, restrict flow to the pump by blocking the inlet with a finger until the iTX goes into flow alarm. A flow alarm is indicated by the pump’s illuminated red fault LED; and by the instrument’s high alarm and display of the word PUMP. To clear the alarm, remove the finger from the pump inlet.

During normal operation the green LED will be illuminated signaling the pump is operating normally. At this point you may connect the probe or tubing combination (up to 100 feet) of your choice and begin remote sampling. Allow 2 seconds per sampling foot as a purge time.

Should the sampling line become obstructed, the iSP will emit an audible alarm and the red fault LED will illuminate. If this occurs, check the sample line for an obstruction or kink. Once the obstruction is removed the iSP will resume normal operation.

USING THE HAND ASPIRATED PUMP*

For remote sampling applications of 10 feet or less, you may choose the hand aspirated sampling pump. Before use, inspect the hand aspirator to ensure it has not been damaged.

To use, simply slide the calibration cup over the sensor end of the iTX, making sure to provide a good seal. Purge the netted reservoir of its contents by completely compressing it. Squeeze the aspirator bulb 10 full consecutive compressions. Verify that each compression inflates the netted reservoir bulb. Proper sampling is obtained when the netted reservoir provides 40 to 80 seconds of constant flow to the calibration cup.

CHARGING

INSTRUMENT/BATTERY

AINTENANCE

With normal routine maintenance the iTX can be relied upon to provide years of reliable service. The following guidelines should be followed when performing maintenance on the iTX.

CLEANING

When necessary, wipe the outside of the instrument with a soft, clean cloth. Never use solvents or cleaning solutions of any type. Make sure the sensor diffusion membrane is free of debris. Clean sensor openings with a soft, clean cloth or soft brush.

CHARGING THE BATTERIES

The lithium-ion battery pack should be fully charged before using the iTX. To charge the battery pack, plug the flying lead from the iTX battery charger into the socket on the back of the instrument. The iTX battery pack will be fully charged within 5 hours. With a fully charged lithium-ion battery pack the iTX should typically function for up to 19 hours (10 hours with iSP sampling pump) of continuous operation. As the battery life decreases, the shaded area of the battery icon in the center of the display will also decrease. With a minimum of 15 minutes of battery life remaining the unit will emit a periodic tone alerting you to charge/replace the battery.

A replaceable cell alkaline battery pack is also available for use with the iTX. To remove the battery pack and replace the 3 AA battery cells loosen the two screws from the battery cover on the back of the instrument. Remove the battery pack and replace the AA battery cells with fresh alkaline batteries. Replace the battery pack and battery cover in the same fashion.

CHANGING GAS SENSORS

iTX sensors are designed to be changed and replaced by the user in the field without the need for factory service. To replace a sensor in the iTX remove the battery from the instrument as described above. Remove the three screws that hold the instrument case top in place and remove the case top. Be careful not to tear the cable that connects the keypad to the display board. Grasp the sensor firmly and remove from the instrument. Plug the new sensor into the open sensor port and press firmly into place. Some toxic gas sensors are shipped with a shorting wire in place on the bottom of the sensor identification board. This shorting wire must be removed prior to installing the sensor in the instrument in order for the sensor to function properly. Once the sensor has been installed, replace the instrument case top and battery pack. New sensors installed in the instrument will be recognized automatically. If a new sensor type was installed in the instrument, the display will prompt the user to calibrate the instrument before further use. After installing any of the bias sensors (NH3, NO, HCl), you must turn on the instrument so the iTX identifies that a bias sensor is installed and recognizes the need to supply a bias voltage. Then turn off the unit and put it on charge for 24 to 48 hours to allow the sensor to stabilize before calibration.

The iTX should be calibrated prior to use to ensure accuracy after a sensor has been changed in the unit.

TOXIC SENSOR CROSS SENSITIVITY CHART
