Case The EAGLE 2’s sturdy, high-impact plastic case is radio frequency (RF) resistant and is suitable for use in many environmental conditions, indoors and out. The case is dust proof and water resistant. It’s two main components, the top case and bottom case, are held together with three screws located on the bottom case. The interface between the top case and bottom case is gasketed. A sturdy, well balanced handle on the top case allows you to hold the instrument comfortably.
Oxygen Sensor The O2 sensor is a galvanic type of sensor. A membrane behind the openings on the sensor face allows gas to diffuse into the sensor at a rate proportional to the partial pressure of oxygen. The oxygen reacts in the sensor and produces a voltage proportional to the concentration of oxygen. The voltage is measured by the EAGLE 2’s circuitry, converted to a measurement of gas concentration, and displayed on the LCD.
Control Buttons Four control buttons are located below the LCD. They are, from left to right, POWER ENTER RESET, DISPLAY ADJUST NO, AIR ▲ YES, and RANGE ▼ SHIFT.
Printed Circuit Boards (PCBs) Display PCB Main PCB I.S. Barrier PCB (not visble) Figure 4: EAGLE 2 PCBs The EAGLE 2’s PCBs analyze, record, control, store, and display the information collected. The main PCB and I.S. barrier PCB are located in the bottom case. The display PCB is located in the top case. The display PCB and I.S. barrier PCB are not user serviceable and are not involved in any user performed maintenance.

infrared port or an 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. Buzzer A solid-state electronic buzzer is located on the front of the top case. It is a panel mounting type of buzzer and is water resistant and sealed to the inside of the top case with an O-ring.
Flow System The EAGLE 2 flow system consists of the inlet fitting, hydrophobic filter, pump, internal tubing, differential pressure (DP) switch, sensor chamber, charcoal filter, and exhaust fitting. Inlet Fitting The inlet fitting is on the right front (when viewed from the front) of the bottom case. It is a nickel plated brass quick connect fitting. It mates with either the sample hose or with the hydrophobic probe.
the O-ring compression force. Charcoal Filter The charcoal filter is located in the front of the flow chamber next to the CO sensor. It contains activated charcoal. The CO sensor will respond if exposed to H2S and certain hydrocarbon gases. The charcoal filter scrubs these gases out of the sample to avoid false CO readings. If false or elevated CO readings are noticed, especially in the presence of H2S, change the charcoal filter.
CAUTION: Sample hose lengths of more than 125 feet are not recommended for the EAGLE 2 because of flow rate reduction and increased response time. Consult RKI Instruments, Inc. for hose lengths longer than 125 feet. The probe includes a replaceable particle filter and hydrophobic filter disk that prevent particulates and water from entering the EAGLE 2’s flow system.
Rechargeable Ni-MH Batteries Rechargeable Ni-MH batteries are available for the EAGLE 2. A fully charged set of Ni-MH batteries will power the EAGLE 2 for 18 hours. The batteries will last for a minimum of 500 charge cycles. See “General Parts List” on page 84 for ordering information.
DC Charger An optional DC powered charger is available with a vehicle plug 12 VDC adapter. It uses the same charging module as the standard AC charger. Vehicle Plug DC Adapter Charging Module Figure 8: EAGLE 2 DC Charger AC/DC Charger A charger is also available that includes both the AC adapter and the 12 VDC vehicle plug adapter. The charging module is the same as the one used for the AC charger and the DC charger.
• 30 inch stainless steel probe Figure 10: 30 Inch Stainless Steel Probe This probe is physically the same as the 30 inch aluminum probe and is intended for applications where a high level of corrosion resistance is required in the long probe tube. • 4 foot stainless steel probe Figure 11: 4 Foot Stainless Steel Probe This probe is designed for areas where it is necessary to put the probe tip in areas that are out of reach for even the 30 inch probes.
• 10 inch probe with dust filter Figure 13: 10 Inch Probe With Dust Filter This probe is designed for use where drawing water or moisture into the EAGLE 2 is not a concern. Instead of a hydrophobic filter, a cotton dust filter is used. • 32 inch telescoping probe with dust filter This probe is designed for use where it is necessary to put the probe tip in areas not accessible with the 10 inch probe with dust filter and applications where the probe tube must be collapsible for storage.
External Dilution Fittings Two external dilution fittings are available for the EAGLE 2, a 1:1 dilution fitting and a 3:1 dilution fitting. They are designed to mate with the inlet fitting and accept a sample hose or probe. The fittings are made with brass and nickel plated brass and are appropriate for use with the four standard gases. The 1:1 fitting is normally used when it is necessary to introduce air into a sample that has no oxygen or a very low level of oxygen, such as a nitrogen purged sample.
Chapter 3: Operation Overview This chapter explains how to use the EAGLE 2 to perform confined space entry monitoring or general area monitoring in Normal Mode. There are three operational modes in Normal Mode: Measuring Mode, Display Mode, and Calibration Mode. While in Normal Mode, the unit is normally operating in Measuring Mode. Display Mode and Calibration Mode are accessible from Measuring Mode. Display Mode is described in this chapter.

Replace the failed sensor as soon as possible. 13. The EAGLE 2 is now monitoring for gas in Measuring Mode. The Normal Operation Screen appears displaying the current gas reading for each target gas. CH4 0%LEL OXY 20.9vol% H2S 0.
Using the Battery Charger for Continuous Operation The battery charger can be used with an AC adapter or a vehicle plug DC adapter to run the EAGLE 2 in continuous operation instead of charging the batteries. Batteries do not need to be installed in the EAGLE 2 but if there are batteries installed, they must be NiMH batteries and they must have a charge.
7. Insert the module’s round plug into the EAGLE 2’s charging jack as shown in Figure 15 below. Figure 15: Connecting the EAGLE 2 to the Charger 8. See “Chapter 3: Operation” on page 22 for instructions for start-up and operation of the EAGLE 2. 9. While the charging module is powering the EAGLE 2, its amber LED will be off and its green LED will be on. Measuring Mode, Normal Operation When the EAGLE 2 completes its startup sequence, it is in Measuring Mode.
Monitoring an Area 1. Start up the EAGLE 2 as described above in “Start Up” on page 22. It is now in Measuring Mode. CH4 0%LEL OXY 20.9vol% H2S 0.0ppm CO 0ppm 2. Take the EAGLE 2 to the monitoring area. Put the probe tip in the area to be monitored. NOTE: If you notice that water has entered the flow system through the probe, replace the probe’s hydrophobic filter and inspect the O-ring for filter particles.

CAUTION: Any rapid increase in the combustible gas reading on the catalytic combustible channel followed by a declining or erratic reading may indicate a gas concentration above the LEL which may be hazardous. • Some gases such as silicone vapors, chlorinated hydrocarbons, and sulphur compounds can contaminate the detection elements inside the combustible sensor damaging the sensor and result in reduced response to combustible gas. Make every effort to avoid these gases.
If the Catalytic Units menu item in Setup Mode is set to CHANGE OK, the standard factory setting, then you can change the catalytic combustible channel’s units by pressing and releasing RANGE ▼ SHIFT. CH4 0%LEL OXY 20.9vol% H2S 0.0ppm CO 0ppm RANGE SHIFT CH4 0.00vol% OXY 20.9vol% H2S 0.0ppm CO 0ppm RANGE RANGE SHIFT SHIFT CH4 0ppm OXY 20.9vol% H2S 0.
The %LEL and %volume unit readings will still increase up to 100% LEL and 15 %volume respectively, which are equivalent to 150,000 ppm. The catalytic combustible sensor is slightly affected by humidity. This is not apparent when the EAGLE 2 is used for %LEL or %volume detection, but because of the high sensitivity in the ppm range, significant humidity changes can affect the ppm reading, especially in the lower part of the range.
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. The EAGLE 2 also sounds an alarm and flashes the LED arrays when one of the target gas concentrations rises above the High Alarm level and when the STEL and TWA alarm levels are reached for CO and H2S.
Table 6: Alarm Types and Indications Alarm Type Visual Indications Audible Indication Low Flow • The display indicates FAIL LOW FLOW LEVEL • Alarm LED arrays flash in a double pulsing pattern once per second • Backlight turns on Double pulsing tone once per second Low Battery Warning • BATT appears vertically along the left side of LCD None Dead Battery Alarm • Gas readings replaced by RECHARGE INSTRUMENT BATTERIES • Alarm LED arrays flash in a double pulsing pattern once per second Double pulsin
are the factory settings. 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. The gas reading must fall below (or rise above for an oxygen low alarm) an alarm setting before you can reset the alarm.
Responding to Over Range Alarms WARNING: An over range condition may indicate an extreme combustible gas, toxic gas, or oxygen concentration. Confirm a normal condition with a different EAGLE 2 or with another gas detecting device. 1. Determine which channel is in alarm. 2. Follow your established procedure for an extreme gas condition. 3. Reset the alarm using the POWER ENTER RESET button once the alarm condition has cleared. 4.
3. If the sensor failure continues, replace the sensor as described in “Replacing a Sensor” on page 80. 4. If the sensor failure condition continues after you have replaced the sensor, contact RKI Instruments, Inc. for further instructions.

If your computer has an infrared port, then no additional accessories are needed to download data from the EAGLE 2. If your computer does not have an infrared port but does have a USB port, a USB/IrDA adapter cable can be used to download data from the EAGLE 2 using the USB port.
Chapter 4: Calibration Mode Overview This section describes the EAGLE 2 in Calibration Mode. In Calibration Mode, you can move through a menu of screens to do the following: • Perform a span adjustment on all channels simultaneously using auto calibration • Perform a span adjustment on one channel at a time using single calibration • Perform a fresh air (zero) adjustment NOTE: You can set up the EAGLE 2 to alert you during the startup sequence when calibration is due.
Calibration Supplies and Equipment To calibrate the EAGLE 2, you will need: • Known calibrating samples of the gases being detected. The combustible and toxic gas samples should have concentrations between 10 and 50% of the full scale value. For example, if you are calibrating the catalytic combustible gas channel, your calibration cylinder should have a combustible gas concentration between 10% LEL and 50% LEL. An oxygen-free source, such as 100% nitrogen is recommended for setting the oxygen zero.
cylinder. This chapter also includes instructions for calibrating one channel at a time using single calibration. Entering Calibration Mode To enter Calibration Mode, do the following: 1. Find a fresh-air environment. This is an environment free of toxic or combustible gases and of normal oxygen content (20.9%). 2. While in Measuring Mode, press and hold the RANGE ▼ SHIFT button, then press the DISPLAY ADJUST NO button and release both buttons. 3.
Calibrating Using the Auto Calibration Method This method allows you to calibrate the CH4 (%LEL sensor), oxygen, H2S, and CO sensors simultaneously. It is designed for use with the RKI 4-gas calibration cylinder and is the quickest and easiest method to calibrate the EAGLE 2. Setting the Fresh Air Reading 1. While in the Calibration Mode Screen, move the cursor to the PERFORM AIR ADJUST menu item by using the RANGE ▼ SHIFT button.

Appendix A: Calibrating with a Sample Bag Overview The EAGLE 2 can be calibrated with a gas bag calibration kit instead of a demand flow regulator kit. This appendix describes how to use a sample bag calibration kit to calibrate the EAGLE 2. A parts list at the end of this appendix lists spare parts for the calibration kit.
To calibrate the EAGLE 2, you will need: • Known calibrating samples of the gases being detected. The combustible and toxic gas samples should have concentrations between 10 and 50% of the full scale value. For example, if you are calibrating the catalytic combustible gas channel, your calibration cylinder should have a combustible gas concentration between 10% LEL and 50% LEL. An oxygen-free source, such as 100% nitrogen is recommended for setting the oxygen zero.

Place the EAGLE 2 upside down on a flat surface or hold it upside down. 3. Unscrew the three case screws until they disengage from the top case. They are captive screws so they will not fall off of the bottom case. 4. Turn the EAGLE 2 right side up and carefully lift the top case away from the bottom case.
10. Hold the PID sensor steady on the working surface with one hand and using the other hand, locate the tabs on the electrode stack removal tool and insert them into the slots on the side of the PID sensor near the face. Figure 27: Using Removal Tool 11. Squeeze the removal tool to push the tabs into the sensor slots until the electrode stack and lamp are released. 12. Carefully lift the PID sensor body away from the electrode stack and lamp.
16. Use this cotton swab to polish the PID lamp window. Use a circular motion, applying light pressure to clean the lamp window. Do not touch the lamp window with your fingers. Figure 29: Polishing the Electrode Lamp Window 17. Continue polishing until you can hear a squeaking sound made by the cotton swab moving over the window surface. This usually occurs after about 15 seconds of polishing. 18. Remove the residual powder from the lamp window with a clean cotton swab.
20. Hold the electrode stack between the thumb and forefinger of one hand and place the window end of the lamp inside the O-ring seal in the electrode stack with the other hand as shown below. Figure 30: Reinstalling the Electrode Lamp 21. Twisting the lamp slightly during insertion will help to ensure the lamp window is snug against the stack's front electrode. The lamp should be supported by the O-ring. 22.
28. Confirm that the main PCB is seated in its slots and that its bottom edge is resting on the bottom of the bottom case. If the main PCB is not seated properly, it may be damaged when the top case is re-installed. 29. Make sure that the top case gasket is fully seated in its groove and carefully put the top case back on the bottom case. If you have any difficulty mating the top and bottom cases, inspect the placement of the main PCB and the placement of the top case gasket. 30.

Appendix M: Tank Tester Model The EAGLE 2 Tank Tester model is intended for checking tanks or vessels that may contain residual hydrocarbon vapors or water or may have been purged of oxygen. It is supplied as an LEL (catalytic) only unit or an LEL (catalytic)/oxygen unit. You can also use this model as a standard EAGLE 2 gas monitor by connecting the standard hose and probe and selection Normal Mode in the Inert Mode Selection Screen.
Float Probe Assembly The float probe assembly helps prevent liquid from being drawn into the EAGLE 2. The float probe assembly is 12-feet long. The hose between both ends of the float probe has an integral cable that connects a switch in the float end to the plug at the other end. This plug connects to the float probe socket that is adjacent to the EAGLE 2’s IR port. A quick connect fitting at the same end of the assembly connects to the EAGLE 2’s inlet fitting.
assembly and must be installed on the EAGLE 2 inlet fitting before installing the float probe assembly when measuring gas in an inert atmosphere. To attach the dilution fitting: 1. Attach the dilution fitting’s male quick connect fitting to the EAGLE 2’s inlet fitting. 2. Attach the float probe assembly to the opposite end of the dilution fitting. NOTE: When using the dilution fitting, multiply the combustible gas reading (LEL or PPM) by 2 to determine the actual combustible gas concentration.
