Page 11: Chapter 1: Introduction
About the EAGLE 2 Using an advanced detection system consisting of up to six gas sensors, the EAGLE 2 sample draw gas monitor is capable of detecting the presence of combustible gas, oxygen (O ), carbon monoxide (CO), hydrogen sulfide S), and various other toxic gases simultaneously.
Page 12 When using the EAGLE 2, you must follow the instructions and warnings in this manual to assure proper and safe operation of the unit and to minimize the risk of personal injury.
Page 13: Specifications
25 ppm * When calibrating the EAGLE 2 with the Auto Calibration or the Single Calibration method, the calibration gas value must be equal to or higher than the alarm 1 setting. See “Updating the Alarm Point Settings” on page 116 for instructions to change the alarm points if necessary for the desired calibration gas value.

IrDA/USB cable connected to a USB port can be used to download data saved by the EAGLE 2 to a computer using the Eagle 2 Data Logger Management Program. See the Data Logger Management Program operator’s manual for data logging and downloading instructions.
Page 24: Flow System
Differential Pressure (DP) Switch The DP switch is inside the front of the bottom case. It senses the EAGLE 2’s flowrate by monitoring the pressure drop between points in the flow system. When the flowrate becomes too low for safe operation of the EAGLE 2, a set of contacts inside it open and the EAGLE 2 indicates a low flow alarm.

Page 34 EAGLE 2 was used. See “Time in Operation Screen” on page 51 for more information about how the EAGLE 2 tracks the operating time. The short-term exposure limit (STEL) reading is reset each time the EAGLE 2 is turned on.
Page 35 The EAGLE 2 will enter Calibration Mode and the LCD will show the Calibration Mode main menu. See “Chapter 4: Calibration Mode” on page 55 for instructions to calibrate the EAGLE 2. When you are done with the calibration and exit Calibration Mode, the unit will begin the startup sequence.

Page 37: Performing A Demand Zero
0ppm Performing a Demand Zero Before using the EAGLE 2, it is recommended to set the fresh air readings for the target gases by performing a demand zero. This will set the CH and CO channels to zero and the OXY channel to 20.9%.
Page 38: Using The Battery Charger For Continuous Operation

1. Start up the EAGLE 2 as described in “Start Up” on page 22. 2. Allow the EAGLE 2 to run for 3 - 5 minutes after the startup sequence is complete and it is in Measuring Mode. This allows the catalytic combustible sensor to stabilize sufficiently for ppm monitoring.
Page 46: Alarm Indications
Alarm Indications The EAGLE 2 will sound an alarm and flash the LED arrays when one of the target gas concentrations rises above the Low Alarm level, or in the case of oxygen falls below the Low Alarm level, for that gas.
Page 47: Resetting And Silencing Alarms
Resetting and Silencing Alarms You can set the EAGLE 2’s gas alarms as latching or self-resetting alarms (see “Updating the Alarm Latching Setting” on page 117). • Self-resetting alarms (ALARM LATCHING set to SELF RESET) Self-resetting alarms automatically shut off and reset when the gas reading falls below (or rises above for an oxygen low alarm) the alarm setting.
Page 48: Responding To Alarms
When the EAGLE 2 goes into gas alarm, press and release any button to silence the buzzer. If the gas concentration was still above the alarm level when the button was pressed, the LED arrays continue to flash, and the EAGLE 2 continues to display the current alarm level.
Page 49 3. Reset the alarm using the POWER ENTER RESET button once the alarm condition has cleared. 4. Calibrate the EAGLE 2 as described in “Chapter 4: Calibration Mode” on page 55. 5. If the over range condition continues or if you are not able to successfully calibrate the unit, you may need to replace the sensor that has triggered the over range alarm.

2 is factory configured for four channels, combustible gas (catalytic sensor), oxygen, H S, and CO, with channels 5 and 6 turned off, the EAGLE 2 can be factory and field configured for a variety of active channels and detector types.
Page 117 CAUTION: Before changing the channel configuration, confirm that the correct sensors and electronic hardware are installed in the EAGLE 2 and that its construction and flow system are appropriate for the installed sensors. Operation of the EAGLE 2 with a flow system or construction not compatible with the installed sensors will result in inaccurate readings.
Page 118 The OP1, OP2, and OP3 options are not defined for a standard 4-gas EAGLE 2. These options are only defined when hardware specific to optional sensors is factory installed in the EAGLE 2. The “---” in the gas name field indicates that hardware necessary to support an optional sensor is not installed.
Page 119: Configuring The Combustible Gas
This menu item allows you to configure the gas for a catalytic, TC (thermal conductivity), or PID (photo ionization detector) sensor. Only a catalytic sensor is used in a standard EAGLE 2, so only a catalytic sensor can be configured in a standard EAGLE 2. PID or TC sensors can only be configured if additional hardware not in a standard EAGLE 2 is factory installed.

Page 277: Appendix J: Methane Elimination Mode
Monitoring in Methane Elimination Mode To monitor an area using methane elimination mode, do the following: 1. Turn on the EAGLE 2 as described in “Start Up” on page 22. 2. Make sure that the EAGLE 2 catalytic combustible channel is set to monitor a gas in which methane elimination is an option.
Page 278 Multiply the display reading by the factor in the appropriate column to determine the actual reading for that gas. For example, if you are using the EAGLE 2 in methane elimination mode to detect isobutane and the display reads 10% LEL, the actual isobutane reading is 10% x 0.59 = 5.9% LEL isobutane.
Page 279 If you are monitoring for isobutane as in the above example and the low alarm is set for 10% LEL, the EAGLE 2 will initiate a low alarm at 5.9% LEL isobutane (display reading of 10% LEL).
