4.1.1ALKALINE BATTERY OPTION

The ATX612 is available with an optional alkaline battery pack which will typically operate continuously for up to 20 hours using 6 C-cell batteries.

!WARNING: Replace alkaline battery cells only in a non-hazardous location. Use only Duracell, Energizer,

Procell, Panasonic, Varta or Kodak C-cell alkaline batteries. Use of another battery type may present a risk of fire or explosion and will violate the intrinsic safety certification of the ATX612.

4.2TURNING THE ATX612 ON AND OFF

•Press and hold the ON/OFF/MODE switch. The display will read HOLD and the instrument sounds a short beep once a second.

•Continue holding the MODE switch for 5 beeps until the RELEASE screen appears. (Stop here if turning the instrument off.)

•After the instrument is turned ON, the following startup screens will be displayed:

SOFTWARE VERSION: The version of the operating software installed in the instrument is displayed.

SENSOR CONFIGURATION. The type of sensors installed in the instrument will be displayed.

WARM-UP TIMER. The display will indicate the number of seconds remaining until the instrument begins normal operation.

After the warm-up sequence has been completed, the ATX612 will enter the normal operating mode and will be continuously monitoring all calibrated sensors.

4.3DISPLAY BACKLIGHT

The display backlight is automatically switched on when the ATX612 is in an alarm condition. To manually activate the backlight, press and release the (E) key. The backlight will remain on for approximately 15 seconds.

4.4INTERNAL SAMPLING PUMP

The ATX612 is equipped with a built-in pump for remote gas sampling. The sampling pump will draw a constant flow sample from up to 100 feet (30 meters) using 1/8 inch (3 mm) diameter tubing.

The remote sample tube should be connected to the barbed inlet fitting on the bottom of the ATX612 (See Figure 3).

NOTE: When drawing a remote sample, allow 2 seconds per foot (0.3 meter) of tubing length in addition to the normal sensor response time before observing the instrument readings.

The instrument is protected from drawing liquid and dust into the pump and sensors by an internal 1.2 micron dust filter/water stop.

4.5OPERATING MODES

The ATX612 offers different operating modes to access various instrument features. To scroll through the operating modes, press and release the MODE switch. The operating modes will appear in the following order:

		O	0
4.5.1	READING
		21 . 0	0
This is the normal operating mode. The current reading of
all sensors is displayed along with the graphical battery
charge indicator.
		CO	H2S
4.5.2	SENSOR CONFIGURATION	02	LEL
This mode will display the type of sensor in the position in
which it is installed in the instrument.
		PPM	EXP
4.5.3	PPM HYDROCARBON
This mode displays the level of total hydrocarbons with 50			0
PPM resolution. The PPM reading may be rezeroed at
anytime by pressing the enter (E) key. The display will
return to the normal operating mode if the gas
concentration exceeds the LEL alarm level set in the
instrument.
4.5.4	ZERO
		ZERO
This mode allows the user to zero the instrument and
calibrate all installed sensors. Refer to Section 5,		PRESS
Calibrating the ATX612, for instruction on the use of the
