Getting Started
WARNING
The D-TEK Select is shipped with the infrared cell and power stick installed. The
nickel/metal hydride batteries in the power stick are not yet charged. To charge
them, connect the cord of the AC power adapter to the power jack at the rear of
the instrument, and plug the adapter into the appropriate mains outlet. The battery
charging light (rear left side) will flash when the detector is charging, changing to
steady illumination when the power stick is charged. Allow 10 hours for the full
charge.
NOTE: You should expect approximately 6.5 hours of operation from a fully
charged power stick. The D-TEK Select will operate off the AC power
adapter. Connecting the supplied AC power adapter will allow operation
of the detector while the power stick charges.
Using Your INFICON D-TEK Select
Do not operate this instrument in the presence of gasoline,
natural gas, propane, or in other combustive atmospheres.
Using the D-TEK Select is simple. Press the power switch once to turn the
detector ON. The green ON LED will illuminate, and the yellow LEDs will
illuminate from left to right in a scrolling fashion while the infrared cell warms up
(approximately 60 seconds). When the detector is warmed up and ready for use,
the yellow LEDs extinguish and you will hear a steady beeping.
The D-TEK Select provides similar responses to all CFC’s, HCFC’s, HFC’s and
refrigerant blends (i.e., R-404A, R407C, R-410A) as well as SF6. There is no
need to select the refrigerant you’re working with.
NOTE: The D-TEK Select does not detect R-11 due to the particular physical
properties of this refrigerant.

Headphone sets may be used with the D-TEK Select. 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, PN 032-0430.
serious hearing damage may occur if other headphone sets are
used.
Finding Leaks
1. 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 (0.5 cm) of the possible
leak source.
2. Slowly (approximately 1 - 2 inches (2.5 - 5 cm) per second) move the probe past
each possible leak point.
NOTE: It is important to move the tip of the probe past the leak to get a
correct reading. The D-TEK Select only responds to changes in
concentration of the refrigerant from the leak. Moving the probe
permits the instrument to respond properly to these changes.
3. When the instrument detects a leak source, its yellow LEDs will illuminate and
it will beep rapdily.
4. When the D-TEK Select signals a leak, pull the probe away from the leak for a
moment, then bring it back to pinpoint the location.
5. If the concentration of the refrigerant gas is high, press the sensitivity switch to
change to the LOW sensitivity setting. The LOW sensitivity setting helps find the
exact site when a leak is large.
6. Once you have isolated the leak source, return the sensitivity setting to HIGH
to continue using the D-TEK Select.
7. When you are done leak checking, press the Power switch to turn the D-TEK
Select OFF.
