Headphone sets may be used with the D-TEK Refrigerant Leak
Detector. When the headphones are plugged into the detector, the
audio signal will only be heard through the headset.

ONLY USE HEADPHONE SETS SUPPLIED BY
INFICON, PART #032-404. SERIOUS HEARING DAMAGE MAY
OCCUR IF OTHER HEADPHONE SETS ARE USED.
Finding Leaks
• Place the tip of the leak-detector probe as close as possible to
the site of the suspected leak. Try to position the probe within
1/4 inch of the possible leak source.
• Slowly (approximately 1-2 inches per second)
move
the probe
past each possible leakage point.
Note:
It is important to move the tip of the probe past the leak to get a
correct reading. The INFICON D-TEK only responds to changes in
concentration of the refrigerant from the leak. Moving the probe permits
the instrument to respond properly to these changes.
• Watch for the yellow lamps to light, and listen for a tone. When
the instrument detects a leak source, its yellow lamps will light,
and it will emit a different audible tone.
• When the D-TEK signals a leak, pull the probe away from the
leak for a moment, then bring it back to pinpoint the location.
• If the concentration of the refrigerant gas is high, slide the
sensitivity switch to LOW before repositioning the probe at the
