A sniffer line connected to the main unit.
The device has run up and warmed up,
The device is calibrated,
see “6.4.2 Calibration”, page 37
You have made the device settings requires for measurement,
You have made the measurement settings requires for measurement,

Measuring position and
speed
Hold the sniffer probe to the possible leak as close as possible. The tip may even touch the
test specimen. If a weldseam or the like is to be tested, the tip should be moved along the
path at a speed of less than 10 cm/s. Please also note the minimum measurement time for
the search for helium,
see “Special features with helium”, page 53
.
Test sequence
1 Keep the sniffer probe away from possible gas sources and press the left key on the
sniffer handle (ZERO).
2 Sniff the test specimen.
If there is a leak, it will be reported in the displays, with flashing LEDs in the sniffer handle
and - depending on your settings - also with an acoustic signal.
Danger of eye damage
LEDs generate a bundled light that can damage eyes.
►
Do not look into the LEDs from a short distance or for a longer period of time.
Electric shock hazard
Sucked in liquids can trigger short circuits and cause damage to property or personal
injury.
►
Do not suction in liquids with the device.
►
Use the water conservation tip in humid environments,

.
Material damage due to a missing sniffer line
The device must not be operated without a connected sniffer line in order to avoid
overpressure in pump and measurement system.
►
Connect the sniffer line before you start up the device.
►
Do not replace the sniffer line while the device is in operation.
