Follow these steps to prepare your DRX3 for operation:

1. Ukufakwa Kwebhethri: Ensure four (4) AA batteries are correctly installed in the battery compartment. The DRX3 typically comes with batteries included.
2. Vula: Press and hold the power button until the unit powers on and the display illuminates.
3. Isikhathi Sokufudumala: Allow the DRX3 to complete its warm-up cycle, which is indicated on the display. This ensures the sensor reaches optimal operating temperature for accurate detection.
4. Zeroing the Unit: In a clean, fresh air environment (free from any potential gas or refrigerant leaks), press the 'ZERO' button. This calibrates the sensor to the ambient air, establishing a baseline for leak detection. Repeat zeroing if moving to an area with different ambient conditions.
5. Khetha Ukuzwela: Choose the appropriate sensitivity level (High, Medium, or Low) using the 'SENSITIVITY' button based on the expected leak size or the environment. Start with high sensitivity for general scanning and reduce it to pinpoint larger leaks.

5. Iziqondiso Zokusebenza

To effectively use your DRX3 leak detector:

1. Indawo yokuskena: Slowly move the probe tip around suspected leak points. Maintain a consistent speed of approximately 1-2 inches per second.
2. Observe Indicators: Pay attention to both the visual display and the audible alarm. The display will show a numerical reading and a bar graph indicating leak intensity. The audible alarm will increase in frequency and pitch as a leak is detected.
3. Pinpointing Leaks: Once a leak is indicated, move the probe away from the area, re-zero the unit, and then slowly approach the suspected leak point again. This helps to isolate the exact source of the leak. Reduce sensitivity if the alarm is constant and overwhelming.
4. Using Auto/Manual Zero: The auto-zero feature continuously adjusts to background gas levels. For more precise pinpointing, switch to manual zero mode after detecting a general leak area.
5. Job Link System App: Connect the DRX3 to the Job Link System app via Bluetooth for real-time data logging, reporting, and integration with other Fieldpiece tools. Refer to the Job Link app's specific instructions for pairing and usage.

6. Isondlo

Regular maintenance ensures the longevity and accuracy of your DRX3:

• Ukushintshwa Kwenzwa: The heated diode sensor (RXA3) is field-replaceable and has a typical life of 300 hours. Replace the sensor when its performance degrades or when prompted by the unit. Refer to the sensor replacement guide for detailed steps.
• Ukuhlanza: Sula iyunithi ngesikhangisoamp cloth. Do not use abrasive cleaners or solvents. Ensure the probe tip is free from debris.
• Ukunakekelwa kwebhethri: Replace batteries when the low battery indicator appears. Remove batteries if the unit will not be used for an extended period to prevent leakage.
• Isitoreji: Store the DRX3 in its blow-molded case in a cool, dry place, away from extreme temperatures and direct sunlight.

7. Ukuxazulula izinkinga

If you encounter issues with your DRX3, consider the following:

• Iyunithi Ayivuliwe:
  • Hlola ukufakwa kwebhethri futhi uqinisekise ukuthi amabhethri masha.
  • Verify battery compartment contacts are clean and free of corrosion.
• Ukufundwa Okungalungile Noma I-alamu Ehlala Njalo:
  • Re-zero the unit in a known clean air environment.
  • Check the sensor tip for obstructions or damage.
  • Consider replacing the heated diode sensor if it has exceeded its typical lifespan or shows signs of wear.
  • Adjust sensitivity settings; high sensitivity in a contaminated area can lead to constant alarms.
• Akukho Ukutholwa:
  • Ensure the unit is powered on and has completed its warm-up cycle.
  • Verify the sensitivity setting is appropriate for the expected leak size.
  • Confirm the sensor is properly installed and functional.
• Connectivity Issues with Job Link App:
  • Ensure Bluetooth is enabled on your mobile device and the DRX3.
  • Restart both the DRX3 and the Job Link app.
  • Check the app for updates.
