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. Long press the power button to turn TEK-Mate On or Off.
4. Wait for TEK-Mate to warm up. All three indicators will illuminate and TEK-Mate
will alarm during warm up. When the HIGH indicator starts flashing and
TEK-Mate beeps about one beep per second, warm-up is complete.
5. To toggle between HIGH and LOW sensitivity modes, press the Power button.
HIGH sensitivity is the default setting.
The INFICON TEK-Mate Refrigerant Leak Detector provides similar responses to
all CFCs, HCFCs, HFCs, HFOs, and refrigerant blends (e.g. R-410A, R407c) as
well as SF6.

How to Install the Alkaline Batteries
1. Remove the battery cover by releasing the latch and sliding the cover down and
off the handle. You may need a screwdriver or similar tool to do this.
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.
NOTES:
Low battery is indicated by the green POWER indicator flashing. TEK-Mate
may continue to operate for up to one hour.
Dead battery is indicated by the POWER and HIGH indicators flashing.
Figure 1. Properly Installed Alkaline Batteries
NOTE: Dispose of depleted alkaline batteries according to applicable state and
local regulations. In the absence of such regulations, recycle and/or
dispose of batteries 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.
WARNING
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
WARNING
Do not operate TEK-Mate 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 probe
tip will affect the air flow over the sensor and cause TEK-Mate to alarm.
1. Turn TEK-Mate On and wait for warm-up to complete.
2. Place the tip of the probe as close as possible to the site of the suspected leak.
Try to position the probe within 1/4 in. (5 mm) of the possible leak source.
3. Slowly (approximately 1 to 2 in. (2.5 to 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. If held on a
leak, the auto zero feature will gradually zero out the leak signal.
4. When the instrument detects a leak, it will beep more rapidly and the indicator
flash rate will increase to signal the leak.
5. When 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, toggle sensitivity
to LOW to make it easier to find the exact site of the leak.
6. Return sensitivity to HIGH before searching for additional leaks.
7. When finished leak-testing, turn TEK-Mate Off.
How to Change the Filter
The foam filter at the probe tip should be replaced if it becomes plugged with
water or oil or appears dirty. To replace the filter, pull out the old filter (with a paper
clip or similar device). Then, push in the new filter.

8
Cleaning and Storage
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 TEK-Mate,
see the Troubleshooting Table below to determine how to remedy the problem. If
you cannot remedy the problem, take TEK-Mate to your wholesaler for evaluation.
PROBLEM CAUSE REMEDY
1. Poor sensitivity.
TEK-Mate does not
find leaks.
1a. Sensor has
reached the end of its
useful life.
1a. Replace the sensor.
See page 6.
1b. Sensitivity set to
LOW instead of HIGH
1b. Set the sensitivity to HIGH
and scan for the leak again.
2. TEK-Mate
responds slowly to a
leak.
2a. Dirty or wet filter. 2a. Replace the filter. See
page 7.
2b. Failure in the
pumping system.
2b. Turn TEK-Mate on and
listen for a high-pitched motor
sound. If you do not hear the
motor, return 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 4 on page 6.
3. Will not power up. 3a. Batteries are worn
out.
3a. Install a new set of
batteries. See page 5.
3b. Batteries have
been improperly
installed.
3b. Check battery installation
as shown in Figure 1. on page
5.

Return Authorization Procedure
All defective TEK-Mates should be returned to your wholesaler for warranty
evaluation. If you have any questions, please contact INFICON at 800-344-3304.
NOTE: Do not return your defective unit directly to the factory without first
contacting your wholesaler.
4. False alarms -
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 TEK-Mate for at least
20 minutes. The absorption of
moisture does not affect the
life or sensitivity of the sensor.
