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 readings to be higher than actual concentrations.

Calibrate the combustible gas sensor after each incident where the combustible gas content causes the instrument to latch in the OVER-RANGE alarm condition.

Silicone compound vapors 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.

Use the RS-232 port 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.

ATX612 F

EATURES

The Industrial Scientific ATX612 Multi-Gas Monitor may be configured to continuously monitor one, two, three or four gases in any combination of the following:

• Oxygen

• Combustible gases (%LEL) or methane (% by volume CH

). User selects %LEL or %CH4prior to calibration.

• Any two of the following toxic gases:

Carbon Monoxide Hydrogen Sulfide Sulfur Dioxide Chlorine Nitrogen Dioxide Chlorine Dioxide

• The ATX612 automatically recognizes and displays the installed sensors when switched on.

• One-Button calibration (microprocessor controlled).

• Built-in pump for remote gas sampling.

• Backlit display for viewing in low light conditions.

• Round-the-clock monitoring capability using the interchangeable rechargeable nickel-cadmium (Nicad) or replaceable alkaline battery packs.

• Plug-in sensors that can be changed or replaced without special tools or soldering equipment.

• 90 dB audible and ultra-bright visual alarm indicators.

• Optional external audible or vibrating alarms.

• High and low alarms for combustible and toxic gases; enrichment and depletion alarms for oxygen.

• User selectable latching alarms.

• User selectable access code for security of calibration and alarm settings.

• Combustible gas OVER-RANGE protection.

• PEAK reading mode.

• Press and hold power switch to prevent accidental turn ON or turn OFF.

• Hygiene/Datalogging option that can be installed by the factory or the customer, to provide short term exposure limit (STEL) and time-weighted average (TWA) readings with 110 hours datalogging capacity.

• The ATX612 is classified as intrinsically safe by the following agencies:

- Underwriters Laboratories (UL).

- Canadian Standards Association (CSA). Canadian

Standards Association has assessed only the combustible gas portion of this instrument for performance.

- Mine Safety and Health Administration (MSHA).

- Workcover Authority, NSW , Australia.

- Department of Mineral Resource, NSW, Australia.

- CENELEC (DEMKO)

NSTRUMENTOPERATION

4.1 CHARGING THE BATTERY

(NICAD BATTERY OPTION)

If the ATX612 is equipped with a Nicad battery pack, fully charge the battery pack before use. A universal charging adapter is included with the unit for charging the ATX612 battery pack. The battery pack may be charged while attached to the instrument or when removed to allow round-the-clock operation of the ATX612 using a spare battery.

The ATX612 is equipped with a nickel-cadmium battery pack with a built-in “smart” charging system. When plugged into the charging adapter, the battery will recharge at a high rate until fully charged and then will reduce to a maintenance trickle charge rate. The battery will not be damaged if it is left connected to the charger for extended periods.

Interchangeable Nicad or Alkaline Battery Pack

A dead battery will be fully recharged in 4.5 hours. The Nicad battery pack has a LED charge status indicator to show the current status when connected to the charger. The LED indicator has five states as follows:

• Solid Amber: Fast charge in progress

• Solid Green: Fully charged, in trickle

charge mode

• Flashing Green: Battery too hot/cold to be

fast charged, in trickle charge mode

• Flashing Amber: Instrument running, fast

charge mode

• Alternating Green/Amber: Trouble, electrical problem

in battery pack

A fully charged Nicad battery pack will typically operate a four-gas configured ATX612 for up to 16 hours. When the instrument is in the normal viewing mode, an eightsegment battery status indicator continuously displays the battery condition. Each segment represents approximately 2 hours of operating time. When the battery is fully discharged, the display will read BATTERY FAIL and the instrument will emit a short beep once a second (See Section 4.6.6). Turn off the instrument and recharge the battery pack when BATTERY FAIL appears.

WARNING: Recharge Nicad battery pack only in a

non-hazardous location.
