2.1 Intended use
The XL3000flex is a helium or hydrogen leak detector for sniffing detection. With the
device you locate and quantify leaks on test objects.
A test object always contains gas under overpressure. Check the exterior of the test
objects for escaping gas using a sniffer line (sniffing method).
• Operate the device only according to this instruction manual.
• Comply with application limits, see "Technical Data".
Misapplications
Avoid the following, non-intended uses:
• Use outside the technical specifications, see "Technical Specifications"
• Use in radioactive areas
• Using the device with detectable defects or defective power switch
• Use of accessories or spare parts, which are not included in this instruction
manual
• Test of wet or damp test objects
• Sniffing of explosive, aggressive, corrosive, flammable, toxic or reactive
substances
• Sniffing of condensable fluids and vapors
• Sniffing of gases contaminated with particles
• Using the sniffer line handle over a long period of time, leading to fatigue.
• Sniffing of gases above the lower explosion limit. The allowable composition of
venal gas mixtures can be read in the safety data sheets of the respective
manufacturers.
• Using the device in potentially explosive atmospheres
• Aspirate liquids into the device via the sniffer line
• Operation at too high ambient temperature
• Inspecting electrically live conductors or objects with a sniffer line
• Using the device as a seat or step
• Raising the device with the handles when the feet are facing up. Otherwise your
hands may get trapped.
• Inserting the sniffer tip into body orifices.
