3.4 Performing measurements
The Ecotec E3000 offers two modes of operation:
• The Standard Operation Mode (compatible to the EcotecII mode)
• The I•Guide Operating Mode
A water-protection tip is available (Cat.-No. 12246) which will protect the Ecotec
E3000 against intake of liquids if necessary. For details on how to install the water
protection tip see
1.6.2 )
3.4.1 Standard Operation Mode
Provided the Ecotec E3000 has been set-up to meet the requirements of the
particular application and it has been calibrated (see Section
3.5 ), a measurement is
run as follows:
First briefly operate the
ZERO
button on the sniffer probe. This will ensure that the
Ecotec E3000 eliminates all interfering influences which may affect the
ZERO
level
(i.e. the detection limit of 0.05 g/a).
Next hold the tip of the sniffer as close as possible to the suspected leak, if required
the tip may even touch the test object.
If a welded seam or alike needs to be tested, the tip should be moved at a velocity of
no more than 10 cm/s (4 inch per second) along the welded seam. The distance
between tip and test sample should be as small as possible.
If a leak is detected the bar will grow. The Ecotec E3000 continuously compares the
measured leak rates with the programmed trigger levels.
If the trigger is exceeded the background color of the probe display will change from
green to red. At the same time an alarm sound will be released by the speaker in the
probe handle and the probe handle will start to slightly vibrate.
As an additional indication of exceeding the trigger value the three white LEDs in the
flange of the sniffer tip will start flashing.
Warning
Danger of electric shock.
Do not touch voltaged parts with the sniffer tip. Test samples need to be
disconnected from electricity before leak testing.
Caution
Do not suck in any liquids.
