Using Your INFICON TEK-Mate
WARNING WARNING WARNING
DO NOT OPERATE THIS INSTRUMENT IN THE PRESENCE OF GASOLINE,
NATURAL GAS, PROPANE, OR IN OTHER COMBUSTIBLE ATMOSPHERES.
How To Find Leaks
NOTE: A sudden whipping of the leak detector probe or blowing into the sensor tip will affect the
air flow over the sensor and cause the instrument to alarm.
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 (5 mm) of the possible leak source.
2. Slowly (approximately 1 to 2 inches/second (25 to 50 mm/second)) move the probe past
each possible leak point.
NOTE: It is important to move the tip of the probe past the leak. If held on a leak, the auto
zero feature will gradually zero out the leak signal.
3. When the instrument detects a leak, it will emit a different tone and the LED flash rate will
increase to signal the leak.
4. When the TEK-Mate signals a leak, pull the probe away from the leak for a moment, then
bring it back to pinpoint the location. If the leak is large, set the sensitivity switch to LOW, by
quickly pressing the main control button, to make it easier to find the exact site of the leak.
5. Return sensitivity to HIGH before searching for additional leaks.
6. When you've finished leak-testing, turn OFF the instrument.
How To Change The Filter
The foam filter at the probe tip should be replaced if it becomes plugged with water or oil. To
replace the filter, simply pull out the old filter (with a paper clip or similar device). Then, push in
the new filter.
Cleaning The TEK-Mate's Housing
The TEK-Mate's plastic housing can be cleaned with standard household detergent or isopropyl
alcohol. Care should be taken to prevent the cleaner from entering the instrument. Since
gasoline and other solvents may damage the plastic, protect your INFICON TEK-Mate from
contact with these substances.
