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",
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,
"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,
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,
