plugged into the detector, the audio signal will only be heard through the headset.
WARNING

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.
