50000 ppm CH4
This selection is for methane (CH
4
) and is the standard factory setting. The LEL
for methane is 5 %volume, or 50,000 ppm. If the gas is configured for this
choice, the methane elimination feature is inactive and the Methane Elimination
Mode Screen will not appear in Display Mode. See “Methane Elimination Mode
Screen” on page 44 for a description of the Methane Elimination Mode Screen.
See “Appendix J: Methane Elimination Mode” for a description of Methane
Elimination Mode.
•
11000 ppm HEX
This selection is for hexane. The LEL for hexane is 1.1%, or 11,000 ppm. If the
gas is configured for this 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 44 for a description of the Methane
Elimination Mode Screen. See “Appendix J: Methane Elimination Mode” for a
description of Methane Elimination Mode.
•
40000 ppm H2
This selection is for hydrogen (H
2
). The LEL for hydrogen is 4%, or 40,000 ppm.
If the gas is configured for this choice, the methane elimination feature is
inactive, the Methane Elimination Mode Screen will not appear in Display Mode,
and the catalytic sensor voltage is set to 1.1 volts. The standard catalytic sensor
voltage is 2.4 volts. Because the detector voltage is set to 1.1 volts, the catalytic
sensor will not respond significantly to methane and many other combustible
gases, but will respond to hydrogen.
WARNING:
Do not configure the catalytic sensor gas to hydrogen if you are
monitoring for general hydrocarbons. Only use this selection if you are
monitoring exclusively for hydrogen or if you do not want to see a
significant response to other combustible gases.
•
18000 ppm IBU
This selection is for isobutane. The LEL for isobutane is 1.8%, or 18,000 ppm. If
the gas is configured for this choice, the methane elimination feature is inactive
and the Methane Elimination Mode Screen will not appear in Display Mode. See
“Methane Elimination Mode Screen” on page 44 for a description of the Methane
Elimination Mode Screen. See “Appendix J: Methane Elimination Mode” for a
description of Methane Elimination Mode.
•
50000 ppm GAS
This selection is for a generic combustible gas with the LEL set to 50000 ppm. If
the gas is configured for this choice, the methane elimination feature will be
active, but the Methane Elimination Mode Screen will not appear in Display
Mode, so methane elimination cannot be turned off. In addition, the relative
response feature is inactive even if it is set to ON in the Setup Mode Relative
Responses menu item.
CAUTION:
The
50000 ppm GAS
gas configuration is normally set at the factory for
very specific applications. Consult RKI Instruments, Inc. before
configuring the gas for
50000 ppm GAS
