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.

5 | What is Cloud Hunting? INFICON
12 / 405 074-708-P16B D-TEK Stratus Operating Manual
5 What is Cloud Hunting?
When refrigerant leaks from a system, it does not disperse evenly in the air. The
concentration of refrigerant is usually higher near the source of the leak. The density
of refrigerants is also different than that of air, so it tends to form “clouds” in the air,
typically closer to the floor. These clouds are colorless and odorless for most
refrigerants. When leak checking with a traditional leak detector, it will likely alarm
when walking into a refrigerant cloud. This does not help you find the leak, because
the cloud may not be near the leak source.
D-TEK Stratus uses patent-pending technology to display the refrigerant concentration
in the air in parts per million (ppm). This allows you to read the display and follow the
number to find areas of higher concentration, leading you straight to the leak source.

6 Charging the Battery
D-TEK Stratus uses a rechargeable lithium ion battery that comes partially charged.
INFICON recommends charging the battery before its first 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 8 to 10 hours of operation, depending on the mode used and the operating
temperature. An on-screen indicator displays the remaining battery percentage.
D-TEK Stratus can be used while charging.

7 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
Stratus 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 Stratus On or Off.
ðD-TEK Stratus begins a variable-time warm-up for 45 to 90 seconds. When
warm-up is complete, D-TEK Stratus is ready to use.
2.
To switch modes, press the MODE button. This toggles between Cloud Hunting,
Pinpoint and Manual Zero modes.
D-TEK Stratus always starts in the last mode that was used.
WARNING
Do not block the exhaust port.
Blocking exhaust air can cause false alarms or readings.

symbol
Cloud Hunting mode is identified by a large ppm reading on the display and the words
Cloud Hunting on the bottom, along with a cloud symbol. The side bar increases and
decreases with changes in the ppm reading.
There is no sensitivity setting in Cloud Hunting mode.
1.
Slowly move through the suspect areas and observe the ppm reading.
2.
Follow the ppm reading to find areas of higher refrigerant concentration. The
higher the number, the higher the concentration.
3.
Press the SENS/ZERO button to enable and disable the MAX feature. When
enabled, the highest ppm level observed is shown below the main ppm display.
To reset the MAX reading, long-press the SENS/ZERO button or toggle the
feature off and back on again.
D-TEK Stratus uses a patent-pending switching valve in Cloud Hunting mode to
constantly compare the sample from the tip of the probe with the air inside the body of
the leak detector (the reference sample). This technology is what allows D-TEK
Stratus to work without the use of a carbon filter. Lingering for several minutes in an
area with a high concentration of refrigerant may cause the reference sample to

become contaminated with refrigerant, which causes the ppm reading to settle back
toward zero. If this occurs, move back to an area with clean air (while in Cloud Hunting
mode) for a few minutes to allow the reference sample to become clean again.

(showing full
alarm)
sensitivity Pinpoint symbol
Pinpoint mode is identified by a large leak indicator on the display and a Pinpoint
symbol on the bottom bar. The current sensitivity is also indicated on the bottom bar.
This mode works like a standard leak detector with auto-zeroing, where the indicator
bars illuminate to indicate when a leak is detected.
1.
Place the tip of D-TEK Stratus 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 Stratus alarms and the on-screen indicator
illuminates.
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 Stratus automatically zeros to the background refrigerant
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 on the bottom bar.

11 Manual Zero Mode

(showing full
alarm)
Manual Zero
symbol
Manual Zero mode looks and operates similar to Pinpoint mode, but is identified by
the text Manual Zero and the Manual Zero symbol on the bottom bar. 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 Stratus 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.
