Try to make the signal stabilize at a value between 20 and 80. When
succeeding, the detector will need another 2-3 seconds to calculate the ethane
concentration. The result is displayed as % C

.
ð
Press check mark to continue. IRwin will ask if you want to "Save Ethane
Concentration for Compensation".
ð
Select "No" if analysis was made for confirming natural gas or "Yes" to use for
compensation. If selecting "Yes" the value is saved as ethane concentration and
shown in the C

field.
See Operating mode “Bar Hole” [ } 58].
ð An ethane concentration value of 1 % or higher is a safe indication of natural
gas. A value between 0.4 and 1 % is a probable indication of natural gas.
If the measured ethane values are between 0 and 2% it is recommended that you
repeat the measurement at least 3 times on the same position to check the result is
consistent.

A number between 0 and 100 appears on the display.
4 If the value is smaller than 20, push the probe harder onto the surface or look
for a place with higher methane concentration. If the value is higher that 80 you
should move the bell away from the leak to find a spot with lower concentration.

An ethane concentration value of 1 Vol% or higher is a safe indication of natural
gas. A value between 0.4 and 1 Vol% is a probable indication of natural gas.
If the measured ethane values are between 0 and 2% it is recommended that you
repeat the measurement at least 3 times on the same position to check the result is
consistent.
