leak test procedure
Always leak test with the engine off.
1.
Charge the system with sufficient refrigerant to have a gauge pressure of at
least 340 kPa (50 psi) with the system off. At ambient temperatures below 15 °C
(59 °F) leaks may not be measurable because the pressure may not be
reached.
2.
Visually trace the entire refrigerant system, and look for signs of air conditioning
lubricant leakage, damage and corrosion on all lines, hoses and components.
Check each questionable area with the detector probe, as well as all fittings,
hose-to-line couplings, refrigerant controls, service valves with caps in place,
brazed or welded areas, and areas around attachment points and hold-downs
on lines and components. If looking for an apparently larger leak, check first at
the medium (7 g/year) or low (14 g/year) sensitivity setting.
3.
Always follow the refrigerant system around in a continuous path so that no
areas of potential leaks are missed. If a leak is found, always continue to test
the remainder of the system.
4.
Recheck the service valves with the caps removed. Blow shop air over the
service valve to clear the immediate area. Check with a detector on the medium
sensitivity setting (7 g/year).
5.
Move the detector at a rate of no more than 75 mm/s (3 in./s) and as close as
possible to 9.5 mm (3/8 in.) from the surface, completely encircling each test
position (switch, sensor, refrigerant tubing connection, etc.).
6.
Slower movement and closer approach of the probe normally improves the
likelihood of finding a leak. However, detectors made to meet this standard are
based on air sampling from the 9.5 mm (3/8 in) distance. A retest is advisable
when a leak appears to be found at the most sensitive settings, particularly if the

probe was in a static position on a joint, or making physical contact with a joint,
as it was moving. Repeat with a moving probe test at that location, taking care
to maintain the small gap (9.5 mm or 3/8 in.) to confirm that the leak is of
repairable size. Checking with the medium sensitivity setting (7 g/year) after
finding an apparent leak with the high sensitivity setting (4 g/year) also may be
helpful.

12 / 357 074-710-P16A D-TEK 3 Operating Manual
5 Charging the Battery
D-TEK 3 uses a rechargeable lithium ion battery that comes partially charged.
INFICON recommends charging the battery before use. Using the supplied charger or
charging cradle accessory, a dead battery can be charged to 80% in approximately 2
hours and 100% in approximately 3 hours. A full charge typically lasts about 9 hours of
operation, depending on the operating temperature. The power indicator indicates the
remaining battery percentage.
Color % Charge
Green >30%
Orange 10–29%
Red <10%
D-TEK 3 can be used while charging.

6 Turning On the Instrument and
Preparing for Use
If the screen does not turn on, the battery is low and needs to be charged. D-TEK 3
can be used while charging.
1.
Long press the power button (located on the left side of the body of the
instrument) to turn D-TEK 3 On or Off.
ðD-TEK 3 begins a variable-time warm-up for 45 to 90 seconds. When warm-
up is complete, D-TEK 3 is ready to use.
2.
To switch modes, press the MODE button. This toggles between Pinpoint and
Manual Zero modes.
D-TEK 3 always starts in the last mode that was used.
English

7 | Pinpoint Mode INFICON
14 / 357 074-710-P16A D-TEK 3 Operating Manual
7 Pinpoint Mode
1.
Place the tip of D-TEK 3 as close as possible to the suspected leak (do not
block the air flow).
2.
Slowly move the probe past each possible leak point.
ðIf a leak is detected, D-TEK 3 alarms and the leak indicators illuminate.
3.
When a leak is identified, pull the probe away from the leak for a few seconds
and then recheck the spot to verify the leak.
In Pinpoint mode, D-TEK 3 automatically zeros to the background refrigerant
concentration and only alarms again with a higher concentration of refrigerant. When
this occurs, either continue looking for a higher concentration of refrigerant or move
the probe to an area of lower concentration for a few seconds to reset the zero point.
Press the SENS/ZERO button to switch the sensitivity setting. When working with a
large leak, it can be easier to pinpoint the leak location using a lower sensitivity
setting. The current sensitivity is displayed by the sensitivity (SENS) indicator.

074-710-P16A D-TEK 3 Operating Manual 15 / 357
8 Manual Zero Mode
Manual Zero mode operates similar to Pinpoint mode, but is identified by the MODE
indicator slowly flashing. Manual Zero mode allows the user to manually zero to the
background refrigerant by pressing the SENS/ZERO button. Once the new zero point
is set, D-TEK 3 will not alarm unless a higher concentration of refrigerant is detected.
Manual Zero mode beeps faster at the zero point than other modes. If the
concentration is lower than the current zero point, the beeping slows. This allows the
user to know if they are moving away from the leak by listening to a change in the
beep rate.
There is no sensitivity setting in Manual Zero mode.
Manual Zero mode requires an extra warm-up time of up to 15 minutes for optimal
performance.

A headphone jack is located on the right side of D-TEK 3 for listening to the alarm
sounds through headphones or earbuds.
WARNING
If attempting to use headphones not supplied by INFICON, be sure to test
them carefully to avoid hearing damage.
A volume button is located next to the headphone jack. Press the volume button to
toggle from 100% volume, to 50% volume, and to mute. The volume defaults to 100%
at startup. When headphones or earbuds are plugged in, the volume toggles between
100% volume and mute.

INFICON Replacing Filters | 12
074-710-P16A D-TEK 3 Operating Manual 19 / 357
12 Replacing Filters
D-TEK 3 uses a hydrophobic filter cartridge that allows air and refrigerants to pass
through while filtering out water, dirt, and oil. Examine the white cloth to determine if
the filter needs to be changed. If the cloth appears discolored, install a new filter.
Changing the filter is also an easy troubleshooting step if you suspect your leak
detector is not properly detecting refrigerants. A clogged air filter can limit the sample
air flow.
probe tip
filter
Exposing the filter to water or oil can block air flow. If this occurs, remove the filter with
the unit turned off and the probe facing down to avoid getting contaminants in the
probe and install a new filter. If the filter is wet, it can be reused once it dries.
CAUTION
Never use the instrument without a probe tip and filter.
To replace the filter:
1.
Unscrew the probe tip and remove the filter.
2.
Insert the new filter into the probe.
3.
Screw the probe tip on. Do not overtighten.

The optional extra-long replacement probe can be used for leak checking in hard-to-
reach areas.
To install the extra-long probe:
1.
Unscrew the standard probe from the D-TEK 3 body using a 10 mm wrench.
2.
Screw on the extra-long probe to approximately 35 in·lb (4 N·m). Do not
overtighten.
3.
Unscrew the probe tip from the standard probe and remove the filter (or use a
new one).
