5. Mode d'emploi

5.1 Powering On and Initial Calibration

1. Appuyez et maintenez enfoncé le bouton d'alimentation pour allumer l'appareil.
2. Allow the device to warm up and perform its automatic zeroing process in a clean, leak-free environment. This ensures accurate readings.

Modes de fonctionnement 5.2

The D-TEK Stratus offers two distinct operating modes for efficient leak detection:

Image: This graphic illustrates the two primary operating modes of the INFICON D-TEK Stratus. The top section shows "Cloud Hunting Mode" with a digital display indicating 1345 ppm, used for finding areas of highest concentration. The bottom section shows "Pinpoint Mode" with a color-coded bar graph, used for precisely locating the leak source.

5.2.1 Cloud Hunting Mode

• Use this mode to quickly scan large areas and identify the general vicinity of a refrigerant leak.
• The display will show refrigerant concentration in parts per million (ppm).
• Move the probe slowly through the suspected area. Higher readings indicate proximity to a leak.

5.2.2 Pinpoint Mode

• Once the general leak area is identified using Cloud Hunting, switch to Pinpoint mode for precise leak location.
• In this mode, the device provides a more focused indication, often with a visual bar graph or escalating audio tone, to guide you directly to the leak source.
• Move the probe very slowly and methodically around suspected leak points.

5.3 Adjusting Sensitivity and Zeroing

• Sensibilité: Press the SENS/ZERO button to cycle through sensitivity levels. Adjust sensitivity based on the size of the suspected leak and environmental conditions.
• Manual Zero: If the device is alarming in a clean environment, move the probe to an area free of refrigerants and press and hold the SENS/ZERO button to perform a manual zero.

6. Informations sur le capteur

The D-TEK Stratus utilizes an advanced infrared sensor for detecting a wide range of refrigerants. The sensor has an expected lifespan of over 2,000 hours.

6.1 Compatible Refrigerants

The standard infrared sensor detects:

• CFCs (Chlorofluorocarbons)
• HCFCs (Hydrochlorofluorocarbons)
• HFCs (Hydrofluorocarbons)
• HFOs (Hydrofluoroolefins)
• A2Ls (Mildly Flammable Refrigerants)

6.2 capteurs optionnels

For detecting other gases, optional sensors are available and can be easily interchanged:

Image: This image displays three different sensor modules for the INFICON D-TEK Stratus. The red sensor is for CFCs, HCFCs, HFCs, HFOs, and A2Ls (included refrigerant sensor). The silver sensor is for flammable refrigerants (requires optional sensor). The green sensor is for CO2 (requires optional sensor). This illustrates the device's versatility with interchangeable sensors.
