Improper use • Do not suck liquids into the leak detector. • Do not suck dirt or sand into the leak detector. • Do not use the IRwin S in areas with potentially explosive atmospheres. See also IRwin-Operating-instructions-mina66en1-12-(1802) 7 / 112...
The charger or car adapter is subsequently connected to the inlet of the Ex Certified IRwin Charging Adapter. This means that the charger for IRwin S must, under no circumstances, be connected directly to the charging socket on any of IRwin models SX, SXT, SXG, and SXGT. See also Charging the battery [} 29].

• The optional Hand Probe Flexible Extension can be connected to the hand probe or rod for easier access. INFICON single-cell IRwin methane leak detector uses the unique INFICON single-cell wide range technol- wide range technology ogy for detecting all concentrations from 1 ppm to 100 Vol% methane. This technology (patent pending) is very sensitive to the ethane content of natural gas.
INFICON Description | 4 IRwin SXG and SXGT models also have GC Ethane Analysis capability for distin- guishing between Natural gas (NG), liquid petroleum gas (LPG) and swamp gas by determining the presence of methane, ethane and propane in the sampled gas.
Risk of explosion due to not approved probe parts. The original INFICON Hand probe is the only part of the probe system that is certified for use in potentially explosive areas. Other parts of the probe system, or third party accessories are not allowed in potentially explosive areas.

INFICON Getting started | 5 Attach the hand probe to the probe rod. Connect the probe tube of hand probe to the gas inlet of the leak detector, see Design of the leak detector [} 13]. Install the probe rod To improve the ergonomics of the carpet probe, you can install the "probe rod exten- extension sion".
5 | Getting started INFICON Remove the O-ring and clean the threaded hole on the black fork on the carpet (where you removed the connector). Place the O-ring flat on the bottom surface of the threaded hole. Screw the extension rod in place in the carpet fork. Make sure the O-ring stays in place by holding the fork vertical.

INFICON Operation | 6 Recommended calibra- • Above Ground CH - weekly tion intervals For calibration in Above Ground mode you need the following gas concentrations: 10 ppm CH , 100 ppm CH , 2.2% CH With this calibration you calibrate the higher range (Vol%) of the modes House and Bar Hole at the same time.
6 | Operation INFICON The methane calibration is possible with gas mixtures in synthetic air only. The natural background of CO (typically 400 ppm) in ambient air will offset the cali- bration. Fresh air exposure should, however, always be by ambient air.
INFICON Operation | 6 You can use different calibration stations for the calibration. However, the following re- quirements have to be fulfilled. • The gas flow delivered by the calibration station must be higher than the flow as- pired by the leak detector. Set the gas flow to at least 80 l/h.
6 | Operation INFICON ð A window appears with controls for adjusting the gas selected. Set the exact gas concentration value via drop-down menus. The leak detector shows the gas to adjust in the window and the currently stored concentration appears just below the setting line.
6.3.1 Select operating mode After finishing the self test the leak detector goes into the operating mode "Ex" ("Above ground" IRwin S). ► Press repeatedly to scroll through the operating modes. The detector is ready to use when the measurement value(s) turn(s) black and the status LED illuminates blue (green for Ex and Ex Tox modes).

INFICON Operation | 6 6.3.3 Operating mode “Bar Hole” This mode is intended for pin-pointing leaks by measuring the concentration in the ground. The detector is ready to use when the measurement value is black and status LED is blue. No gas alarms are given in this mode.
6 | Operation INFICON Measurement range Measurement range 0.5 Vol% - 100 Vol% CH 0.1 Vol% - 20 Vol% CO You can readjust the zero point of the CH Vol% value if needed. This can be done if deviation is within +/- 5 Vol%. Press lower left button if "0" appears in blue.

INFICON Operation | 6 6.3.7 Operating mode "Gas Purity” This mode is intended for checking that the gas has reached a certain point in the net- work when a previously purged section is refilled. WARNING No gas alarms are given in this operation mode! This operating mode is intended for the measurement of higher gas concentrations.
