California Aire Resource Board (California Industrial Dry Cleaning Report, Feb 2006).
Electrochemical heated-diode sensor.
Automatic adjustment ("zeroing") to Perchloroethylene in leak test area.
Rugged flexible probe with a foam filter for sensor protection.
High/Low sensitivity and power in one switch.
To get the best performance from your TEK-Mate Leak Detector, please read this manual
carefully before you start using it. If you have any questions or need additional assistance,
please call 800-344-3304. We'll be happy to help you!

Getting Started
1. Install the batteries. See How To Install The Alkaline Batteries.
2. Install the sensor. See How To Install Or Change the Sensor.
NOTE: Installation of the batteries and sensor is required before use.
3. Press the control button to power on the TEK-Mate.
4. Wait for the TEK-Mate to warm up. All three LEDs will illuminate during warm up. When the
High sensitivity LED starts flashing and a chirping sound is heard, the TEK-Mate is ready to
find leaks.
How To Install The Alkaline Batteries
1. Remove the battery cover by releasing the latch and sliding the cover down and off the
handle.
2. Install two “D” size alkaline batteries as shown in Figure 1.
3. Reinstall the battery cover by aligning it with the handle and sliding it up until the latch
engages.
When the batteries reach the end of their life, the green Low Battery indicator will start flashing.
While the batteries may operate the TEK-Mate up to one hour after the Low Battery indicator
starts flashing, the batteries should be replaced as quickly as possible.
Figure 1. Properly Installed Alkaline Batteries
Disposing Of The Alkaline Batteries
At the end of the life of a set of alkaline batteries, please dispose of them according to
applicable state and local regulations. In the absence of such regulations, INFICON encourages
customers to recycle and/or dispose of the cells through voluntary waste recycling programs.

How To Install Or Change the Sensor
A new TEK-Mate is shipped with its sensor packed separately. The sensor must be installed
before use. This specialized sensor will operate for about 100 hours before it will need to be
replaced.
1. Remove the rubber sensor cover by lifting at the outer edge.
2. If you are replacing a worn out sensor, remove the worn out sensor by pulling it straight out
of the socket and discard it.
WARNINGWARNINGWARNING
IF YOU ARE REPLACING THE SENSOR, THE WORN OUT SENSOR
MAY BE HOT.
3. Remove the new sensor from its packaging and carefully align the three sensor leads (small
wires coming out of the bottom of the “can”) with the three holes in the sensor socket. Insert
the leads into the holes by gently pressing straight down on the sensor until the sensor leads
contact the bottom of the socket. Be careful not to bend the sensor leads. See Figure 2.
4. Reinstall the rubber sensor cover by pressing it down firmly around the edges. Be sure the
edges of the cover are flat against the surface of the detector.

Using Your INFICON TEK-Mate
WARNINGWARNINGWARNING
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.

Troubleshooting
Except for the batteries and the sensor, the internal parts of the TEK-Mate Leak Detector are
not user serviceable. If you experience a problem with your TEK-Mate, see the Troubleshooting
Table below to determine how to remedy the problem. If you can not remedy the problem, take
your TEK-Mate to your wholesaler for evaluation.
PROBLEM CAUSE REMEDY
1. Poor sensitivity. The
TEK-Mate does not find
leaks.
1a. Sensor has reached
the end of its useful life.
1a. Replace the sensor.
See page 5.
1b. Sensitivity set to LOW
instead of HIGH
1b. Set the Sensitivity to HIGH and
scan for the leak again.
2. The TEK-Mate
responds slowly to a leak.
2a. Dirty or wet filter. 2a. Replace the filter. See page 6.
2b. Failure in the pumping
system.
2b. Turn the TEK-Mate on and
listen for a high-pitched motor
sound. If you do not hear the
motor, return the TEK-Mate to your
wholesaler for evaluation.
2c. The sensor cover is
not sealing.
2c. Make sure the sensor cover is
properly installed. See step 5 on
page 5.
3. Will not power up. 3a. Batteries are worn out. 3a. Install a new set of batteries.
See page 4.
3b. Batteries have been
improperly installed.
3b. Check battery installation as
shown in Figure 1. on page 4.
4. False alarms - the
TEK-Mate alarms when
the probe is moved or
bumped.
4a. Sensor leads are bent. 4a. Remove the sensor and
inspect the leads. Straighten the
leads with needle nose pliers, if
necessary, and reinstall the
sensor.
4b. Moisture was
absorbed by the sensor
during a long period
without use.
4b. Run the TEK-Mate for at least
20 minutes. The absorption of
moisture does not affect the life or
sensitivity of the sensor.
