INFICON Sensistor ILS500 Leak Detection System - Manual (Page 42)

42 Using the ILS500
ninb63e1-f (1410)
8.2.2 Place the Test Object
1 Place the test object in the Test Chamber or connect it to one, two or more
connection ports.
2 Connect any extra equipment needed.
8.2.3 Perform a Test
Automatic Gas Test
1 Press Start on the ILS500 or wait approximately 4 seconds if automatic start is
activated.
2 When ready – Check the result on the display and lamps.
Manual Gas Test
1 Press Start on the ILS500.
2 Move the Hand Probe close to and along the pressurized test object.
3 A chime sound indicates the detection/location of a leak. A small leak can be more
precisely located by moving the probe over the leak again.
4 Remove the probe promptly.
5 Check the result on the display and lamps.
Caution
Do not expose the probe to a hydrogen concentration greater than 0.1% when the
instrument is not operating, as this could damage or destroy the probe sensor.
Caution
When the instrument is put into operation the sensor withstands temporary
exposure to hydrogen concentration up to 100%. Avoid long exposures to high
concentrations.
Notice For more information about manual testing, refer to ISH2000 manuals and
manual(s) for chosen probe(s).
It is good practice to detect a leak, locate it, and then immediately remove
the Hand Probe to avoid saturation. The probe is not damaged by long
time exposure, but it will recover more slowly. After excessive exposure,
the probe will be less sensitive for a short period of time.
