EAGLE 2 Operator’s Manual Using Setup Mode • 111
• 10000 ppm - - - *
This selection is a user defined selection. The factory setting is 10000
ppm - - - *, with the asterisk (*) indicating that it is user defined. If
this selection has been updated in the field, it will appear differently,
but the asterisk will always remain next to the menu item to indicate
it is user defined. If you choose the user defined selection, the unit
will prompt you to enter four parameters: a three character gas name,
the LEL value in terms of ppm, the response factor relative to
methane, and the detector voltage. When you configure the gas as the
user defined choice, the methane elimination feature is active and the
Methane Elimination Mode Screen is accessible in Display Mode.
See “Methane Elimination Mode Screen” on page 43 for a
description of the Methane Elimination Mode Screen. See “Appendix
J: Methane Elimination Mode” for a description of Methane
Elimination Mode.
5. Use AIR ▲ YES and RANGE ▼ SHIFT to move the cursor next to the
desired gas for the catalytic channel.
6. If you placed the cursor next to one of the pre-defined gases, press and
release POWER ENTER RESET to select the gas and proceed to Step 15.
If you placed the cursor next to the user defined gas with the asterisk (*),
press POWER ENTER RESET and proceed with Step 7.
7. The user defined gas setup screen appears with the first character of the
gas name flashing. The current gas name and range are shown on the top
line of the screen.
8. Enter the gas name. Use AIR ▲ YES and RANGE ▼ SHIFT to display
the desired character, then press POWER ENTER RESET to enter the
displayed character and move to the next character. Repeat until all three
characters are entered. When the last character is entered, the ppm ratio
value will be flashing.
9. Use AIR ▲ YES and RANGE ▼ SHIFT to display the desired ppm
value. This value is called the ppm ratio and must be the ppm equivalent
of the LEL for the gas being defined. For example, if you are defining
propane, the LEL for propane is 21,000 ppm, so you must enter 21000
ppm (2.1% volume).
