Conversion Table Tab
The Conversion Table tab is used to view the pre-defined relative
response gases for the catalyti c combustible channel and to edit or add
user-defined gases. The pre-defined gases can be found in the
Pre-Defined Table tab while the user-defined gases can be found under
the User-Defined Table tab.
Figure 12: Conversion Table
There are 8 columns in both the Pre-Defined Table tab and the UserDefined Table tab:
•No
This column represents the gas number. The gas numbers are 1-30.
•Name
This is what will appear in the Relative Response list of gases. The
name can be up to 3 characters long and the characters must be
upper case letters or numbers. No special characters may be used in
the Name column.
•Long Name
The Long Name column is used to better describe the target gas. It
17 • Conversion Table Tab
may contain any character in upper- or lower-case.
•Factor
This value is the response factor for the listed gas relative to
methane. The factor for each pre-defined gas is factory defined.
The factor for any user-defined gases must be obtained through
testing as described in “Obtaining a Relative Response Factor” on
page 28. Even if not all of the user-defined catalytic combustible
channels are being defined, the Factor column must have a valid
number entered. A valid number for the Factor is a value between
0.01 and 25.00.
•1st
This column is for the low alarm point of each gas in ppm units.
•2nd
This column is for the high alarm point of each gas in ppm units.
•Ratio
The ratio is the ppm value of the LEL for each gas. This value is
specific to each gas and can be easily determined. The maximum
value it may be set to is 150,000 ppm. If an invalid number is
entered, the box will turn red when the csv file is imported back
into the Maintenance Data Loader Program.
NOTE: If you define a gas whose LEL is above 50,000 ppm, the
%LEL reading in Measuring Mode will reflect the defined
ppm ratio, but the ppm reading in Measuring Mode will not
indicate above 50,000 ppm. For example, if you set the ratio
to be 150,000 ppm and set the catalytic combustible channel
to display the reading in ppm, the gas reading will not
indicate higher than 50,000 ppm, the equivalent of 33 %LEL
and 5% volume for this ratio, but will continue to indicate
%LEL readings up to 100 %LEL and %volume readings up to
15 %volume, the equivalent of 150,000 ppm, if the display
units are changed to %LEL or %volume. In addition, all
adjustable ppm parameters cannot be set higher than 50,000
ppm.
Conversion Table Tab • 18
•Volt
This value determines the sensor voltage for the catalytic
combustible sensor. It can be set to 1.3 or 2.4. When set to 1.3, the
sensor is in methane elimination mode. When set to 2.4, the sensor
is reading at full response. Even if not all of the user-defined
catalytic combustible channels are being defined, the Volt column
must have a valid number entered. A valid number for the Volt
column is either 1.3 or 2.4.
While the pre-defined gases may not be edited, the 5 user-defined
gases may be edited by doing the following:
1. With the Maintenance Data Loader Program running, click on the
Conversion Data tab and then click on the User-Defined Table tab.

•Full Scale
This is the full scale value for the target gas.
•Point
The point value indicates to what decimal place the gas readings are
shown. A value of 1/1 indicates a r eading to th e “ones” plac e whil e
a value of 1/100 indicates a reading to the “hundredths” place.
•Unit
The unit describes what units the gas reading is provided in. All
units are in ppm. While this parameter may be changed in the csv
file, units of ppm are the only acceptable units and changing this
parameter to %LEL or %vol will change the unit box to red.
•Digit
The digit is the increment of the gas readings.
•1st
This column is for the low alarm point of each gas in ppm units.
•2nd
This column is for the high alarm point of each gas in ppm units.
•STEL
The STEL column displays the STEL values for each gas.
•TWA
The TWA column displays the TWA values for each gas.
•AutoCal
The AutoCal values are those that come up during the auto
calibration procedure. They are default values that may be changed
if the gas concentration in the calibration cylinder is different.
•Factor
This value is the Relative Response Factor for the PID channel. The
factor for each pre-defined gas is factory de fined. The factor for the
user defined gas must be obtained from Table 4 on page 29 or
through testing as described in “Obtaining a Relative Response
Factor” on page 28. A valid character for the Factor is a value
between 0.01 and 25.00.

Obtaining a Relative
Response Factor
If the gas that you want to monitor on the catalytic combustible or PID
channel is not included in the catalytic or PID relative reasponse lists,
you may define up to 5 gases for the catalytic combustible channel
using the Conversion Table tab and 1 gas for the PID channel using the
PID Sensor tab. Testing must be done using the desired target gas in
order to obtain the response factor value for the catalytic combustible
channel. To determine the relative response factor value for the PID
channel, first look in T able 4 for the desired gas. If the desired gas does
not appear in the table, you must obtain the response factor through the
testing procedure described below.
To determine the relative response factor value for the catalytic or PID
channels, do the following:
1. For determining the catalytic combustible channel relative
response factor, calibrate the catalytic combustible channel to
methane. For determining the PID channel relative response factor ,
calibrate the PID channel to isobutylene.
2. Obtain a gas sample of known concentration for the target gas you
wish to define. The sample needs to be at least 10% of the full
scale but RKI Instruments, Inc. recommends using 50% of the full
scale. If the concentration tested results in an overscale reading,
test a lower concentration.
3. Apply the gas sample to the EAGLE 2 and take note of the reading.
If the gas sample is of 50 %LEL concentration and the EAGLE 2
display shows a reading of 25 %LEL, then the factor for that gas is
2. Conversely, if the gas sample is of 50 %LEL concentration and
the EAGLE 2 display shows a reading of 100 %LEL, then the
factor for that gas is 0.5. This conversion factor value is what you
will enter in the Factor column of the gas you are defining.
Table 4 below has 4 columns:
•Gas/VOC-The most common name for the VOC (volatile organic

compound)
•CAS No.-Sometimes it is easier to identify a VOC from the

•Response Factor (RF)-The relative response factor for each gas.
This is the value that is plugged into the Eagle 2 Maintenance Data
