6.4.7 Measuring
Preparation

A sniffer line is connected to the basic unit.

The device has started up and is warmed up, see "6.1 Switching on the device",
page 29 .

The device is calibrated, see "6.4.6.1 Time and type of calibration", page 43 .

You have configured the measurement settings required for your measurement, see
"6.4 Settings for the measurements", page 41 .

If you check areas which are difficult to reach then you can also insert an extended and,
if desired, flexible sniffer tip,
see "5.3.3 Use flexible sniffer tips", page 25 .

Alternatively, you can attach an extension hose to the sniffer tip at the front, see "5.3.4
Using an extension hose for a sniffer tip", page 26 .
Carrying out a
measurement To carry out measurements, be aware of the following:
► Hold the sniffer tip close to the potential leak.

The tip must touch the test object.
► If you want to test a weld seam or similar, you must guide the tip along the path at a
speed of less than 2.5 cm/s.
► When you check a spot, hold the sniffer line to it for least 1 second.
Risk of electric shock
Electrical voltages can be transmitted via the sniffer probe and cause damage to proper-
ty or personal injury.
►
Do not touch live parts with the sniffer probe.
►
Disconnect electrically operated test objects from the mains before starting the leak
test and secure them against being restarted without authorization.
Risk of eye damage
LEDs generate a bundled light that can damage your eyes.
►
Do not look into the LEDs from a short distance or for longer periods of time.
Risk of electric shock
Sucked up liquids can trigger short circuits and cause property damage or personal
injury.
►
Do not suck up liquids into the device.
►
Use the water conservation tip in humid environments, see "5.3.1 Replacing the
sniffer tip", page 24 .
