2. Características clave
The DR58 is equipped with several features to enhance leak detection efficiency:
- Ultra-Sensitive Heated Diode Sensor: Detects micro leaks as small as <0.03 oz/yr, offering 20 times greater sensitivity than traditional bubble methods.
- Universal Refrigerant Compatibility: Capable of detecting all HFC, CFC, HCFC, HFO, H2N2 (Tracer Gas), and blended refrigerants used in HVACR systems.
- Durable e de longa duración: Features an IP54 rating for resistance against moisture and oil, ensuring reliability in various working conditions. The sensor has a typical life of 300 hours.
- Clear Leak Indicators: A large, backlit LCD screen displays leak size and intensity using a bar graph and numeric readings. An LED tip and audible beep provide immediate feedback for precise leak pinpointing.
- Flexible Probe and Extended Battery Life: A 17-inch flexible probe allows access to tight spaces. The rechargeable USB battery provides up to 18 hours of continuous operation. Replaceable filter tips are included.

3. Configuración
Before initial use, ensure the DR58 is properly set up and charged.
3.1 Desembalaxe e compoñentes
Your Fieldpiece DR58 package should include:
- 1 x Heated Diode Refrigerant Leak Detector (DR58)
- 5 x Replacement Filtered Tips (RFT6)
- 1 x Blow-Molded Case
- 1 x Heated Diode Sensor (RHD1) (pre-installed or separate)
- 1 x USB Charging Cable and Wall Adapter

3.2 Carga inicial
- Connect the USB charging cable to the DR58's charging port.
- Plug the other end of the cable into the wall adapter and then into a power outlet.
- Allow approximately 6 hours for a full charge. The battery indicator on the LCD will show charging status.
3.3 Sensor and Filter Tip Installation
- Asegúrese de que o dispositivo estea apagado.
- If the heated diode sensor (RHD1) is not already installed, carefully insert it into the end of the flexible probe until it clicks into place.
- Screw a filtered tip onto the end of the sensor. Ensure it is finger-tight to prevent debris from entering the sensor.
4. Funcionamento
Follow these steps for effective leak detection with your DR58.
4.1 Acendido e quecemento
- Press and hold the power button (blue button with sun icon) for approximately 1 second to turn on the device.
- The DR58 will display 'Warm' and then 'AZERO' as it warms up and performs an automatic zeroing. This process typically takes less than 10 seconds.
4.2 Zeroing the Device
Zeroing establishes a baseline for the ambient air, allowing the detector to accurately identify refrigerant concentrations above this baseline.
- Automatic Zeroing: The device automatically zeros upon power-on and continuously adjusts to background refrigerant levels during operation.
- Manual Zeroing: To manually zero the device, move the probe to an area known to be free of refrigerant. Press the 'ZERO MANUAL/AUTO' button. The display will show 'AZERO' to confirm.
4.3 Axuste da sensibilidade
The DR58 offers adjustable sensitivity levels to suit different leak detection scenarios.
- Press the 'SENSITIVITY MAX ON/OFF' button to cycle through sensitivity levels (High, Medium, Low).
- Use higher sensitivity for smaller leaks or when the leak source is difficult to pinpoint. Use lower sensitivity in areas with higher background refrigerant levels to avoid false positives.
4.4 Procedemento de detección de fugas
- Slowly move the flexible probe along the suspected leak area, such as refrigerant lines, coils, and connections. Maintain a consistent speed of approximately 1-2 inches per second.
- Observe the LCD display for increasing bar graph segments and numeric readings, indicating the presence of refrigerant.
- Listen for the audible beep, which will increase in frequency and pitch as the leak source is approached.
- The LED tip on the probe will also illuminate red, intensifying as the leak concentration increases.
- Once a leak is detected, move the probe away from the area and then slowly re-approach to confirm the exact location.

5. Mantemento
Regular maintenance ensures the longevity and accuracy of your DR58.
5.1 Replacing Filter Tips
The filter tips prevent debris from entering the sensor. Replace them regularly, especially in dirty environments, or if they appear clogged.
- Unscrew the old filter tip from the sensor.
- Screw on a new replacement filter tip (RFT6) until it is finger-tight.
5.2 Substitución do sensor
The heated diode sensor (RHD1) has a typical life of 300 hours. Replace the sensor when its performance degrades or if the device indicates a sensor error.
- Power off the DR58.
- Unscrew the filter tip.
- Gently pull the old sensor out of the probe.
- Insert the new RHD1 sensor into the probe until it clicks into place.
- Re-attach a clean filter tip.
5.3 Limpeza
- Limpe o exterior do dispositivo cun damp pano. Non use produtos de limpeza ou disolventes abrasivos.
- Ensure the sensor and filter tip are free from oil, moisture, and debris.
6 Solución de problemas
