Overview
This chapter briefly describes the EAGLE 2 gas monitor. This chapter also describes the EAGLE
2 Operator’s Manual (this document). Table 1 at the end of this chapter lists the specifications for
the EAGLE 2.
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 (O2), carbon
monoxide (CO), hydrogen sulfide (H2S), and various other toxic gases simultaneously. The
EAGLE 2’s rugged, reliable, and easy-to-use design makes it ideally suited for a wide range of
applications, including sewage treatment plants, utility manholes, tunnels, hazardous waste sites,
power stations, petrochemical refineries, mines, paper mills, drilling rigs, and fire fighting
stations. The EAGLE 2 offers a full range of features including:
• Simultaneous monitoring of one to six gases. The standard configuration includes four sensors
for combustible gas (%LEL, ppm, and %volume), oxygen, carbon monoxide (CO), and
hydrogen sulfide (H2S).
• Choice of three operating modes:
• Normal Mode for typical confined space or area monitoring. Normal Mode is the
standard factory setting.
• Bar Hole Mode for checking of bar holes when searching for underground gas leaks
• Leak Check Mode for locating leaks in valves and piping
• Sample-drawing pump with up to 125 foot range
• Liquid crystal display (LCD) for complete and understandable information at a glance
• Ultrabright alarm LEDs
• Distinctive audible alarm for dangerous gas conditions or unit malfunction
• Microprocessor control for reliability, ease of use, and advanced capabilities
• Data logging functions (when used in Normal Mode)
• Alarm trend data (when used in Normal Mode)
• STEL and TWA (when used in Normal Mode) and over range alarms
• Peak readings (when used in Normal Mode)
• Built-in time function
• Lunch break feature
• RF shielded high impact plastic case
• CSA classified for Class I, Division I, Groups A, B, C, and D hazardous atmospheres

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. A clear plastic window is located on the top case to the front of the handle for
viewing the LCD.
A removable battery case is located at the rear of the bottom case. A thumbscrew secures the
battery case to the bottom case. The interface between the battery case and the bottom case is
gasketed. Six raised feet on the bottom of the case, four on the bottom case and two on the battery
compartment, raise the EAGLE 2 slightly from the surface on which it rests.
Sensors
The EAGLE 2 uses up to six sensors to monitor combustible gas, oxygen (O2), carbon monoxide
(CO), hydrogen sulfide (H2S), and various other toxic gases simultaneously. The sensors are
located inside the EAGLE 2 bottom case and are installed in the flow chamber. The sensors
described below are the four standard sensors. See pg. 124 for a description of the PID sensors,
pg. 163 for a description of the ESM-01 toxic sensors, pg. 184 for a description of the TC sensors,
pg. 200 for a description of the IR CO2 sensors, pg. 214 for a description of the IR methane
sensors, and pg. 226 for a description of the IR hydrocarbon sensor. The standard sensors use
different detection principles as described below.
Catalytic Combustible Gas Sensor (LEL Sensor)
The catalytic combustible gas (LEL) sensor detects combustible gas in the %LEL range. It uses a
catalytic element for detection. The reaction of gas with oxygen on the catalyst causes a change in
the resistance of the element which changes the current flowing through it. The current is
amplified by the EAGLE 2’s circuitry, converted to a measurement of combustible gas
concentration, and displayed on the LCD.
The LEL sensor housing includes a sintered metal flame arrestor on one end that allows gas to
diffuse into the sensor. On the other end, five pins extend from the sensor. The sensor cable
connects to these pins on one end and terminates in a four-position connector on the other end
which plugs into the HC socket on the main PCB (see Figure 5 on page 19).
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.
The sensor includes a short cable that terminates in a round 7-position connector. It mates with the
OXY pins on the main PCB (see Figure 5 on page 19).

www.GlobalTestSupply.com
CO and H2S Sensors
The CO and H2S sensors are electrochemical sensors that consist of three precious metal
electrodes in a dilute acid electrolyte. A gas permeable membrane covers the sensor face and
allows gas to diffuse into the electrolyte. The gas reacts in the sensor and produces a current
proportional to the concentration of the target gas. The current is amplified by the EAGLE 2’s
circuitry, converted to a measurement of gas concentration, and displayed on the LCD.
The CO and H2S sensors are physically very similar. Except for their markings and wire colors,
they look almost identical. A three-position connector at the end of a 2-wire cable from each
sensor plugs into a socket on the main PCB. The sockets on the main PCB for the CO and H
S
2
sensors are labeled CO and H2S. Normally, the CO connector plugs into the CO socket and the
H2S plugs into the H2S socket. However, because of the way that the main PCB circuitry is
arranged, if the CO sensor is plugged into the H2S socket and the H2S sensor is plugged into the
CO socket, the sensors will still operate properly and the CO and H2S readings will still appear on
the channels that are programmed for those gases.
LCD
A digital LCD (liquid crystal display) is visible through a clear plastic window in the top case.
The LCD simultaneously shows the gas reading for all installed sensors. The LCD also shows
information for each of the EAGLE 2’s operating modes.
Control Buttons
Four control buttons are located below the LCD. They are, from left to right, POWER ENTER

the PCB behind the IR port on the front of the bottom case.
Alarm LEDs
Two sets of red alarm LEDs (light emitting diodes) are visible through two raised, frosted plastic
lenses in the top case. Each set has two LEDs. They are above the LCD, one above the left corner
and one above the right corner. The alarm LEDs alert you to gas, low battery, and failure alarms.
Infrared Communications Port
An infrared (IR) communications port is located on the left front of the bottom case when the
instrument is viewed from the front. The data transmitted through the port is in standard IrDA
protocol. A computer’s 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. The buzzer

sounds for gas alarms, malfunctions, low battery voltage, and as an indicator during use of the
EAGLE 2’s many display and adjustment options.
Battery Case & Batteries
Four C-size alkaline batteries (standard) or optional rechargeable
C-size Ni-MH batteries power the EAGLE 2. They are installed in the battery case which is
located at the rear of the bottom case. The battery case is secured to the bottom case with a
thumbscrew.
Instrument run time is dependent upon battery type. At 25°C, alkaline batteries power the EAGLE
2 for 16 hours of non-alarm operation. Ni-MH batteries will power the EAGLE 2 for 18 hours of
non-alarm operation. The current battery voltage is viewable in Display Mode (see pg. 41).
When the EAGLE 2 detects low battery voltage, a low battery warning is activated. When battery
voltage is too low for operation, the EAGLE 2 sounds a dead battery alarm.
The alkaline or Ni-MH batteries can be accessed for replacement by unscrewing the thumbscrew
that secures the battery case to the bottom case and pulling the battery case away from the bottom
case. The Ni-MH batteries can be recharged by using the EAGLE 2 charger (see pg. 67).
NOTE: Use of batteries or battery chargers not specified by RKI Instruments, Inc. will void the
CSA classification and may void the warranty.
WARNING: To prevent ignition of a hazardous atmosphere, batteries must only be changed
or charged in an area known to be nonhazardous.
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.
Hydrophobic Filter
The hydrophobic filter is located in the bottom case above the sensors. Normally the hydrophobic
probe accessory (see pg. 21) will prevent water and particulate contamination from entering the
flow system, but if the probe is not used, the hydrophobic filter will stop water and particulates
from penetrating further into the flow system. If it becomes dirty or water logged, replace it (see
pg. 71).
Pump
A diaphragm pump inside the rear of the bottom case draws the sample to the sensors. It can draw
sample from as far as 125 feet from the EAGLE 2.
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 sample hose lengths longer than 125 feet.
Internal Tubing
The flow system includes polyurethane tubing to route the sample between the various
components of the flow system. The internal sample tubing is not user serviceable.
20 • Chapter 2: Description EAGLE 2 Manual
Find Quality Products Online at: sales@GlobalTestSupply.com
www.GlobalTestSupply.com
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.
Sensor Chamber
A PVC block in the bottom case is configured to accept the four gas sensors. It routes the sample
to each sensor. The LEL sensor and the oxygen sensor are retained in the sensor chamber by
brackets. The CO and H2S sensors are each pushed past two sealing O-rings into the chamber and
are retained by 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.
The charcoal inside the filter cannot be replaced; the entire filter must be replaced.
Exhaust Fitting
The exhaust fitting is located below the inlet fitting. It routes the gas sample out of the EAGLE 2.
It includes a female 10-32 thread that can be used for the installation of a hose barb or other type
of fitting that has a male 10-32 thread so that the exhaust can be routed to a particular location
with flexible tubing if desired.
Standard Accessories
Standard accessories include the shoulder strap, the sample hose, and the hydrophobic probe.
Shoulder Strap
A comfortable elastic shoulder strap clips to the EAGLE 2 at the front and rear of the top case. It
clips to stainless steel rings that are installed in features on the top case. It can be removed from
the EAGLE 2 by opening the clip at each end of the strap and removing it from the strap ring at
the front and rear of the top case.
Hose and Probe
A 5 foot polyurethane sample hose and a 10 inch hydrophobic probe are included as standard. The
hose has a male quick connect fitting on one end and a female quick connect fitting on the other
end. The probe has a male quick connect fitting. Normally, the male end of sample hose is
installed in the EAGLE 2 inlet fitting and the probe is installed in the female end of the hose.
However, if the sample hose is not needed for monitoring a particular area, the probe may be
installed directly to the inlet fitting. Sample hose lengths are available from 5 feet (standard
length) to 125 feet (see “Chapter 7: General Parts List” on page 78). A Teflon lined hose is
provided with all units that contain a PID sensor. This hose must be used when operating a PID
EAGLE 2 (see pg. 124).
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.

NOTE: When using the probe with a PID EAGLE 2, be sure that the particle filter is not
installed.
Optional Accessories
Several optional accessories are available for the EAGLE 2. They include rechargeable Ni-MH
batteries, battery chargers, various special probes, and dilution fittings. The most commonly used
optional accessories are described below. Detailed instructions regarding the use of these and
other available accessories are included in other parts of this manual. Data logging accessories are
briefly described on pg. 40.
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 “Chapter 7: General Parts List” on page 78 for ordering information.
Battery Chargers
Three battery chargers are available for the EAGLE 2 to charge the optional Ni-MH batteries, the
standard AC charger, a DC charger with a vehicle plug adapter, and an AC/DC charger with a
vehicle plug adapter.
AC Charger
The standard AC charger consists of the charging module, which includes all of the charging
circuitry, and an AC adapter. The charging module includes a five foot cable with a connector on
the end that mates with the EAGLE 2 charging socket. The AC adapter plugs into a 115 VAC wall
outlet and connects to the charging module with a jack on the end of a five foot DC output cable.
The AC adapter will also work for 100 VAC or 220 VAC if an appropriate plug adapter is
provided.

Figure 10: 30 Inch Stainless Steel Probe
Figure 11: 4 Foot Stainless Steel Probe
Figure 12: Barhole Probe
Various optional probes designed for specific applications are available for the EAGLE 2. They
include the following:
• 30 inch aluminum probe
This probe is designed for applications where it is necessary to put the probe tip in areas that
are out of reach with the standard probe. A small breather hole near the end of the probe tube
prevents interruption of sampling and a low flow alarm if the probe tip is blocked.
• 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
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. A stainless steel probe tube is used because the length of
the probe tube requires a high degree of rigidity. Stainless steel is more rigid than other
normally used materials. A small breather hole near the end of the probe tube prevents
interruption of sampling and a low flow alarm if the probe tip is blocked.
• Barhole probe
This probe is designed specifically for barhole testing. See “Appendix K: Using the EAGLE 2
in Bar Hole Mode” for an in-depth discussion of using the EAGLE 2 in Bar Hole Mode.

See “Chapter 7: General Parts List” on page 78 for probe ordering information.
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. Both the 1:1
and 3:1 fittings can also be used when one of the target gas levels in the sample area will likely be
present in a concentration above the detection range for that gas. Since the fittings partially
consist of unplated brass, they are not appropriate for detection of elevated levels of H
gases that are easily absorbed such as Cl2 or SO2.

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.
WARNING: Use the EAGLE 2 charger’s continuous operation mode to power the EAGLE
2 only if NiMH batteries are installed in the EAGLE 2 or if no batteries are
installed in the EAGLE 2. Do not use the charger for continuous operation if
alkaline batteries are installed.
1. Place the EAGLE 2 in the area to be monitored.
2. Plug the power adapter into either an AC outlet or into a vehicle outlet depending on which
charger is being used.
3. Set the switch on the module to “CONT. OPERAT.”.
4. Make sure the EAGLE 2 is off.
5. Make sure the adapter and module are connected.
6. Make sure that the NiMH batteries are either charged or removed.
NOTE: If the batteries are not charged, the EAGLE 2 will not turn on and will instead give a
“Charge Batteries” indication when it is powered up after Step 7 below.
7. Insert the module’s round plug into the EAGLE 2’s charging jack as shown below.

Measuring Mode, Normal Operation
When the EAGLE 2 completes its startup sequence, it is in Measuring Mode. In Measuring Mode
the EAGLE 2 continuously monitors the sampled atmosphere and displays the gas concentrations
present for its target gases. In a low-light environment, press and release any button to turn on the
display backlight. See pg. 109 to program backlight duration. If the Confirmation Alert feature is
turned on in the Setup Mode menu (see pg. 114), the EAGLE 2 beeps periodically to confirm that
it’s operating.
Monitoring an Area
1. Start up the EAGLE 2 as described above in “Start Up” on page 26. It is now in Measuring
Mode.
2. Take the EAGLE 2 to the monitoring area.
Put the probe tip in the area to be monitored.
NOTE: If the particle filter or hydrophobic filter become dirty or clogged, replace them. If
water enters the probe, dry out or replace the particle filter (if installed) and shake any
water out of the probe or off of the hydrophobic filter. 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. See pg. 70 for instructions to replace the particle
filter and the hydrophobic filter.
3. Wait 10 - 15 seconds and observe the display for gas readings. If a reading is observed, allow
the reading to stabilize to determine the gas concentrations present.
NOTE: Response time increases with the length of the sample hose. Long sample hoses will
require more time to show a response at the EAGLE 2. The maximum sample hose
length recommended for the EAGLE 2 is 125 feet. Consult RKI Instruments, Inc. for
longer sample hose lengths.
4. If a gas alarm occurs, take appropriate action. See pg. 39.

Using Optional Sample Hoses
The standard sample hose for the EAGLE 2 is 5 feet long. Optional hoses are available up to 125
feet long. If you are considering using a longer hose, keep in mind that a longer hose will increase
the EAGLE 2’s response time and the flowrate may decrease close to the low flow alarm point.
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 chart below illustrates how response time is affected by the sample hose length.

Using Exhaust Tubing
The EAGLE 2’s exhaust fitting has a female 10-32 thread to allow for the installation of a hose
barb fitting with a 10-32 thread to which a flexible exhaust tube can be connected. If you utilize
this feature, the tubing used must have a minimum internal diameter of 1/8 inch. RKI Instruments,
Inc. recommends using flexible polyurethane tubing with a maximum exhaust tube length of 20
feet. Consult RKI Instruments, Inc. for exhaust tubing lengths longer than 20 feet.
Combustible Gas Detection
There are three issues to keep in mind when monitoring for combustible gas.
• The catalytic combustible sensor will respond to any combustible gas. The standard
calibration gas for the EAGLE 2 catalytic combustible channel is methane (CH4). If the
instrument is calibrated to a different combustible gas, such as hexane or propane, the gas
name for the catalytic combustible channel will reflect the target gas.
The table below lists the conversion factors for several hydrocarbon gases if the EAGLE 2 is
calibrated to methane. To use this table, multiply the display reading on the combustible gas
channel by the factor in the appropriate row to obtain the actual gas concentration. For
example, if you are detecting pentane and the display reads 10% LEL for the catalytic
combustible channel, you actually have 10% LEL x 1.95 = 19.5% LEL pentane present.

* Vapor pressure too low for significant LEL reading
• The EAGLE 2 provides the catalytic combustible sensor with some protection against
exposure to high levels of combustible gas which can damage the sensor. It does this by
turning off the combustible sensor power temporarily when it determines that an over scale
(more than 100% LEL) concentration of combustible gas is present that may damage the
sensor. Nevertheless, concentrations of combustible gas of more than 100% LEL can still
affect the zero level or calibration of the combustible sensor if the concentration is high
enough.
CAUTION: Do not expose the catalytic combustible sensor to high concentrations of
combustible gas such as that from a butane lighter. Exposure to high
concentrations of combustible gas may adversely affect the performance of the
sensor.
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. The
catalytic combustible sensor has an integral H
S scrubber for protection from H2S exposure
2
resulting from normal use, but you should avoid exposure to high levels of H2S and other
sulphur compounds.

The standard factory configuration for the EAGLE 2 allows the user to use the RANGE ▼ SHIFT
button to change the displayed detection units of the catalytic combustible channel between
%LEL, ppm, and %volume. It is possible to disable this capability and set the EAGLE 2 to
display only one of the detection units by using the Catalytic Units menu item in Setup Mode. See
“Setting the Catalytic Detection Units (CATALYTIC UNITS)” on page 104 for instructions to set
this Setup Mode Menu item.
The detection range of the combustible catalytic channel when set for ppm or %volume will
correspond to 0 - 100% LEL for the configured gas. For example, the LEL for methane (CH4) is
5% volume, or 50,000 ppm. So if the catalytic combustible channel is displayed in terms of
%volume, the full scale is 5.00% and if it is displayed in terms of ppm, the full scale is 50,000
ppm.
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.
Monitoring Combustible Gas in the PPM Range
There are special considerations that must be taken into account when monitoring combustible
gas in the ppm range with the catalytic combustible channel. Because of the high sensitivity in the
lower part of the ppm range, the catalytic combustible channel needs more time than the warm-up
period to stabilize after the EAGLE 2 is turned on if it is going to be used for ppm level detection.
The reading increments in the ppm range are smallest in the lower part of the range and increase
as the reading increases as follows:
• 5 ppm increments from 0 ppm to 200 ppm
• 10 ppm increments from 200 ppm to 1,000 ppm
• 50 ppm increments from 1,000 ppm to 10,000 ppm
• 250 ppm increments from 10,000 ppm to 50,000 ppm

EAGLE 2 Manual Chapter 3: Operation • 35
www.GlobalTestSupply.com
If the catalytic combustible channel is configured for the user defined gas in Setup Mode (see
“Configuring the Combustible Gas (CONFIGURE GASES)” on page 100), the ppm ratio defined
for the gas must be considered. For example, if the ppm ratio is set higher than 50,000 ppm, then
when the display units are set as ppm, the reading will not go above 50,000 ppm which is
equivalent to 33 % LEL and 5 %volume. So if the gas reading is higher than 50,000 ppm, the ppm
unit reading will indicate 50,000 ppm and also indicate an overscale condition. 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. Take care to allow the unit to acclimate to a new environment for about a minute and
perform a demand zero in a fresh air location when you move between areas of different humidity.
CAUTION: If the catalytic combustible channel is being calibrated with a gas concentration of
1000 ppm or lower, the a 24 inch humidifier must be used for accurate calibration.
See “Chapter 5: Calibration Mode” on page 53 for more explanation and
instructions for calibration.
To monitor for combustible gas in the ppm range:
1. Start up the EAGLE 2 as described on pg. 26.
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.
NOTE: This extra stabilization period is not necessary if monitoring in the %LEL or %volume
range.
3. Set the catalytic combustible channel’s units to be ppm by using the RANGE ▼ SHIFT
button.
4. Perform a demand zero as described on pg. 30.
5. Proceed to monitor for gas as described on pg. 32.

Measuring Mode, Alarms
This section covers alarm indications in Measuring Mode. It also describes how to reset the
EAGLE 2 after an alarm has occurred and how to respond to an alarm condition.
NOTE: False alarms may be caused by radio frequency (RF) or electromagnetic (EMI)
interference. Keep the EAGLE 2 away from RF and EMI sources such as radio
transmitters or large motors.
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.
NOTE: If an alarm condition occurs while you are in Display Mode, the EAGLE 2 will
automatically bring up the alarm screen instead.
When a failure condition occurs, such as a sensor failure, low flow, or dead battery condition, the
unit will also sound an alarm and flash the LED arrays.

Resetting and Silencing Alarms
You can set the EAGLE 2’s gas alarms as latching or self-resetting alarms (see pg. 107).
• 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. You cannot reset self-resetting alarms
with the POWER ENTER RESET button. You can set self-resetting alarms with or without the
alarm silence feature (see pg. 107).
• Latching alarms (ALARM LATCHING set to LATCHING)
Latching alarms will remain in effect until the gas reading falls below (or rises above for an
oxygen low alarm) the alarm setting and they are reset with the POWER ENTER RESET
button. You can set latching alarms with or without the alarm silence feature (see pg. 107).
ALARM SILENCE On and Alarms Set to LATCHING:
ALARM SILENCE set to ON and ALARM LATCHING set to LATCHING 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. When the alarm condition passes, press and release the POWER ENTER
RESET button to reset the alarm. The LED arrays turn off and the EAGLE 2 alarm indications on
the display turn off.

Responding to Alarms
This section describes response to gas, over range, battery, and sensor failure alarms.
Responding to Gas Alarms
1. Determine which gas alarm has been activated.
2. Follow your established procedure for an increasing gas condition or a decreasing oxygen
condition.
3. If necessary, reset the alarm using the POWER ENTER RESET button once the alarm
condition has passed.
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. Calibrate the EAGLE 2 as described on pg. 53.
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.
6. If the over range condition continues after you have replaced the sensor, contact RKI
Instruments, Inc. for further instructions.
Responding to Battery Alarms
WARNING: The EAGLE 2 is not operational as a gas monitoring device during a dead
battery alarm. Take the Model EAGLE 2 to a non-hazardous area and replace
or recharge the batteries as described in “Replacing or Recharging the
Batteries” on page 67.
The EAGLE 2 is fully functional during a low battery warning. However, only a limited amount
of operating time remains, approximately 1 - 2 hours. The amount of time depends on how often
the LCD backlight is used and how often the unit is responding to alarm conditions. Recharge the
Ni-MH batteries or replace the alkaline batteries as soon as possible as described on pg. 67.
NOTE: Alarms and the LCD back light consume battery power and reduce the amount of
operating time remaining.

Responding to Sensor Failure Alarms
1. Determine which sensor has triggered the sensor failure alarm.
2. Try calibrating the sensor first, as described on pg. 53 before replacing it.
3. If the sensor failure continues, replace the sensor as described on pg. 74.
4. If the sensor failure condition continues after you have replaced the sensor, contact RKI
Instruments, Inc. for further instructions.
Data Logging
NOTE: The EAGLE 2 only logs data while in Normal Mode. If the EAGLE 2 is used in Leak
Check Mode or Bar Hole Mode, no downloadable data will be logged.
The EAGLE 2 features the ability to log data to its internal memory and download it to a
computer via the infrared communications port on the front of the unit. It logs gas readings during
normal operation, alarm data, and calibration data.
To utilize the EAGLE 2’s downloading capability, you will need the Eagle 2 Data Logger
Management Program and a computer with an infrared port or a USB port that runs one of the
following operating systems: Windows 7, Windows 8, or Windows 10. 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. The Eagle 2 Data
Logger Management Program is available at www.rkiinstruments.com/eagle2. The USB/IrDA
adapter cable is also available from RKI Instruments, Inc.
The data logging capacity depends on how often the EAGLE 2 stores data, how many channels
are active, and how often the EAGLE 2 is turned on and off. The table below illustrates how much
data logging time is available for the various interval times. It assumes that the unit is setup with
four sensors, is only turned on once, and there are no alarm occurrences. See pg. 110 for
instructions on setting the data logging interval time.

Catalytic Sensor Relative Response Screen
This screen displays only if RELATIVE RESPONSE in Setup Mode is set to ON (see pg. 104).
Use this screen to temporarily change the gas configuration of the catalytic combustible channel.
You can select from a list of gases whose response relative to the configured gas, normally
methane, is programmed into the EAGLE 2’s memory. This includes several pre-defined gases
and 5 gases that can be entered into the EAGLE 2 in the field using the Eagle 2 Maintenance Data
Loader Program. In order to program a field defined gas into the EAGLE 2, gas testing must be
performed to determine the gas’ response factor relative to methane. See the Eagle 2 Maintenance
Data Loader Program Operator’s manual for details regarding the gas testing and programming
user defined gases into the EAGLE 2’s relative response list. The last five items in the gas list are
reserved for field defined gases.
The relative response feature enables you to temporarily monitor for the selected gas without
having to recalibrate the EAGLE 2. The EAGLE 2 will clear the gas configuration change when it
is turned off and will return to the programmed configuration when it is turned on again.
Because of normal variation between sensors, these relative response factors are typical factors. If
you use this feature, the response to the selected gas will not be as accurate as it would be if you

Chapter 5: 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. See “Updating the Calibration Reminder Setting (CAL REMINDER)” on
page 112
CAUTION: BEFORE EACH DAY’S USAGE, SENSITIVITY IN THE %LEL RANGE MUST BE
TESTED ON A KNOWN CONCENTRATION OF THE COMBUSTIBLE TARGET
GAS, METHANE, EQUIVALENT TO 25 - 50% OF FULL SCALE
CONCENTRATION (the %LEL full scale is 100 %LEL). ACCURACY MUST BE
WITHIN -0 to + 20% OF ACTUAL. ACCURACY MAY BE CORRECTED BY
FOLLOWING THE CALIBRATION INSTRUCTIONS FOR THE COMBUSTIBLE
CHANNEL BELOW.
If the combustible channel passes the above response test and does not require calibration, the unit
should still be calibrated periodically. The optimum frequency of calibration depends heavily on
how the EAGLE 2 is used. For example, instruments used daily may need to be calibrated weekly
or monthly, while instruments that are used only a few times a year may need to be calibrated
before each use. Typical calibration frequencies range from monthly to quarterly. Make sure to
perform the combustible channel response test as described above and make sure to develop a
calibration schedule tailored to your application that takes this test and required calibration
resulting from this test into account.
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.
NOTE: The catalytic combustible channel can be set up for and calibrated to a number of
different combustible gases. See pg. 100 for instructions. Be sure that you are using an
appropriate calibration cylinder for the target gas of the catalytic combustible channel.
CAUTION: When using auto calibration with the standard 4-gas EAGLE 2, although the
EAGLE 2 can be calibrated with an oxygen concentration of up to 19.5%, RKI
Instruments, Inc. recommends that the multi-gas cylinder have an oxygen
concentration in the range of 10% - 16% oxygen.

• Non-absorbent tubing
• A 24 inch humidifier tube if you are calibrating the catalytic combustible channel with a gas
concentration of 1000 ppm or lower
WARNING: If you are using a calibration kit that includes a gas bag and a fixed flow
regulator or dispensing valve, do not apply gas directly to the EAGLE 2 with
the regulator or dispensing valve or damage to the pump will result. See
“Appendix A: Calibrating with a Sample Bag” on page 81 for instructions to
properly use a gas bag kit.
To calibrate the %LEL, oxygen, CO, and H
need for a zero-oxygen source, you can use the auto calibration feature with a 4-gas cylinder. If
the H

11. Press and release the POWER ENTER RESET button to perform the calibration.
12. When the span adjustment is made, the EAGLE 2 calculates the range of adjustment,
minimum and maximum, it could have made based on its response level to the applied gas.
This calculated range is independent of the calibration gas value that was entered in Step 8
and Step 9 above. The adjustment range is included on the result screen to indicate the
condition of the sensor. If the calibration gas value is in the adjustment range, the span
adjustment will pass. If the calibration gas value is out of the adjustment range, the span
adjustment will fail.
If the span adjustment is successful, the following screens display.
In the example above, the EAGLE 2 could have adjusted the reading as low as 35 %LEL and
as high as 98 %LEL.
If the span adjustment is not successful, a screen displays that indicates a calibration failure.
In the example above, the EAGLE 2 could have adjusted the reading as low as 11 %LEL and
as high as 43 %LEL. Since the calibration gas value entered was 50 %LEL, the unit failed the
span adjustment. The buzzer and alarm LED arrays activate in a double pulsing pattern. Press
and release the POWER ENTER RESET button to reset the alarm and return to the Select
Sensor Screen. Attempt to calibrate again. If the failure continues, investigate the cause. See

Checking the Combustible Gas Sensor’s Condition
If you suspect that the combustible sensor has been contaminated or may be reaching the end of
its operational life, do the following to confirm it is still operating properly:
1. Perform a calibration using single calibration as described in “Calibrating Using the Single
Calibration Method” on page 60.
2. When you perform the span adjustment, note the adjustment range on the result screen as
described in Step 12 and Step on page 63.
3. A new sensor can typically be adjusted to more than twice the calibration gas concentration.
If the result screen indicates that the EAGLE 2 could not adjust the combustible gas reading
to be at least 10% higher than the calibration gas concentration, then the sensor should be
replaced as soon as possible.

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.
Calibration Supplies and Equipment
EAGLE 2 Manual Appendix A: Calibrating with a Sample Bag • 81
Find Quality Products Online at: sales@GlobalTestSupply.com
www.GlobalTestSupply.com
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.
NOTE: The catalytic combustible channel can be set up for and calibrated to a number of
different combustible gases. See “Configuring the Combustible Gas (CONFIGURE
GASES)” on page 100 for instructions. Be sure that you are using an appropriate
calibration cylinder for the target gas of the catalytic combustible channel.
CAUTION: When using auto calibration with the standard 4-gas EAGLE 2, although the
EAGLE 2 can be calibrated with an oxygen concentration of up to 19.5%, RKI
Instruments, Inc. recommends that the multi-gas cylinder have an oxygen
concentration in the range of 10% - 16% oxygen.
• A gas collection bag with hose clamp
• A 6 LPM fixed-flow regulator or a dispensing valve
WARNING: RKI Instruments, Inc. recommends that you dedicate a regulator for use
with chlorine (Cl
for any other gases, particularly hydrogen sulfide (H
) gas and that you do not use that dedicated regulator
2
S).
2
• Calibration tubing
To calibrate the combustible gas, oxygen, CO, and H2S sensors at the same time, automatically,
with no need for a zero-oxygen source, you can use the auto calibration feature with a 4-gas
cylinder. If the H2S channel is not active, then a 3-gas cylinder may be used for auto calibration.
This document includes instructions for auto calibration with a fixed flow regulator or dispensing
valve, a sample bag, and a 4-gas cylinder. This document 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. If the unit prompts you for the password, enter it by using the AIR ▲ YES and RANGE ▼
SHIFT buttons to select each password number and then pressing and releasing POWER
ENTER RESET to enter the number and move on to the next one.

This menu item allows you to set the channel type for each of the six channels or to turn one or
more channels off. Although the standard EAGLE 2 is factory configured for four channels,
combustible gas (catalytic sensor), oxygen, H2S, 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.
It is not normally necessary to change the factory channel configuration.
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. Consult RKI Instruments, Inc. if you cannot confirm
either of these items.
1. From the main menu, place the cursor next to CONFIGURE CHANNELS.
2. Press and release POWER ENTER RESET. The Configure Channels screen appears with the
cursor flashing next to CH1.
The standard 4-gas configuration is shown below.
3. Use AIR ▲ YES or RANGE ▼ SHIFT to move the cursor next to the channel you want to
configure.

In the example below, channel 3 has been selected for configuration.
5. Use AIR ▲ YES and RANGE ▼ SHIFT to move the cursor next to the desired configuration
for the selected channel. In the example below, the cursor has been moved next to the NOT
USED selection.
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. If your EAGLE 2 supports one or more of these optional
sensors, the target gas will appear instead of “---”. See “Appendix C: Sub PCBs” on page 120
for a description of this optional hardware and how it affects CHANNEL
CONFIGURATION.
6. Press and release POWER ENTER RESET to select the channel configuration. In the
example below, channel 3 has been turned off by selecting NOT USED.
7. Repeat Step 5 and Step 6 for any other channels you want to configure.
8. Use RANGE ▼ SHIFT to move the cursor next to the END menu item.
NOTE: If you want to exit to the main menu without saving any channel configuration
changes, press and release DISPLAY ADJUST NO.

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.
1. From the main menu, place the cursor next to CONFIGURE GASES.
2. Press and release POWER ENTER RESET. The Configure Gases Screen appears with the
cursor flashing next to CAT.
The OP1, OP2, and OP3 options are not defined in a standard 4-gas EAGLE 2. These options
are only defined when hardware specific to optional sensors is factory installed in the
EAGLE 2. See “Appendix C: Sub PCBs” on page 120 for a description of this optional
hardware and how it affects CONFIGURE GASES.
3. To change the catalytic sensor gas configuration, press and release POWER ENTER RESET.
4. A screen appears with gas configuration choices for the catalytic channel.
For each gas, the LEL (lower explosive limit) and gas name is displayed. The LEL is shown in
terms of ppm. The available choices are on two screens.
