DocumentDocumentHeated Diode Refrigerant Leak Detector OPERATOR'S MANUAL Model DR58 Description Compact and rugged, the DR58 Heated Diode Refrigerant Leak Detector helps you find leaks fast in the field. Its heated diode sensor detects all HFC, HCFC, CFC, HFO, and blends. Multiple indicators and sensitivity 20x higher than soap bubbles make it easy to track down even the smallest leaks in various environments. A red LED flashes at the tip so you can keep your eyes on the target. The large bars on the backlit LCD are easy to see in bright sunlight or low light, and the numerical value provides an extra digit of resolution. Unlike conventional leak detectors, you have full control with both an automatic (AZERO) and manual (MZERO) zero mode. The large Li-ion rechargable battery provides over 18 hours of continuous operation and is convenient to charge via USB-C. Replaceable tips filter out water and dust while getting into tight spots. All wrapped up in a ruggedized IP54 housing, it's built for the field.

Do not use this device in a combustible gas atmosphere or with A3 refrigerants such as R-290, propane or R-600, isobutane. Do not block exhaust port or device or will not function properly. 02 03 04 05 Quick Start 1. Install sensor (see next panel for details). 2. Move to a refrigerant-free environment and hold until your DR58 powers on. 3. Allow warm-up (calibration) to complete. Total used sensor hours is also displayed. 4. Begin searching for the leak source. Move the tip slowly (~3 inches/sec) and as closely as possible to the suspected refrigerant line. 5. Search until refrigerant gas is detected. Red light flashes, audible alarm triggers, and the display indicates the relative gas concentration. 6. Confirm leak source. Move tip away from alarm location for a few seconds to clear the sensor. Return tip back to suspected leak, looking for the highest value. Sensor Installation 1. Ensure your DR58 is powered off. 2. Remove the 3 screws of the sensor cap. 3. Pull the sensor cap away from the back case. 4. If replacing, pull out the old sensor. 5. Push new sensor (RHD1) into pin holes. Pin orientation does not matter. 6. Push sensor cap back onto back case and secure with the 3 screws. 7. If replacing, hold and SENSITIVITY 5 sec to reset sensor hours. Hold ZERO to confirm or to cancel. Heated Diode Sensor (RHD1) Maintenance CLEANING: Clean the exterior with a damp cloth. Do not use detergents or solvents. BATTERY CHARGING: Recharge the internal battery as needed using the USB-C cable. In addition to the AC plug, most generic USB ports supply enough power to charge. The long life Li-ion rechargable battery is permanently installed. To maximize battery life, minimize time spent at 100% full or 0% full. SENSOR REPLACEMENT: Depending on gas exposure, the RHD1 sensor should be replaced after approximately 300 hours of use. FILTER REPLACEMENT: The hydrophobic filter is built into the replaceable tip and should be replaced periodically to maximize sensor life and performance. Five filtered tips (RFT6) are included. Unscrew the tip to remove. Functionality Test Use a refrigerant tank and a cap to check if your DR58 is detecting refrigerant properly. 1. Tightly cap a refrigerant tank port to seal it. 2. Open valve to coat the inside of the cap, then close the valve. 3. With DR58 set to high sensitivity (H), remove the cap and wave the tip over the cap. You should see a very large leak size of approximately "99" and a full bar graph. If not, the filtered tip or sensor may need to be replaced. Filtered Tip (RFT6) 06 07 08 09 10 Operation Power Press >1 second to toggle power. Backlight Press to toggle the blue backlight. Zero Modes (AZERO/MZERO) DR58 starts up in automatic zero mode (AZERO) which sets a new zero point every two seconds, indicated by AZERO blinking twice. Moving closer to the leak source will show the relative increase in concentration, triggering the alarm. Conversely, stopping at or moving away from the leak source will not trigger a response. Press MANUAL/AUTO >1 second to toggle manual zero mode (MZERO). DR58 does not zero automatically while MZERO is displayed and will continue to alarm and display the relative leak size. Zero Set Press ZERO to manually set the currently measured concentration to 0, indicated by AZERO/MZERO blinking twice. 11 12 More HVACR Products from Fieldpiece EXHAUST PORT (DO NOT BLOCK) STATUS BAR - Sensitivity - Mute - Battery MESSAGE LINE SPEAKER CHARGING PORT Numerical Leak Size Indicator with Bar Graph The number is the relative concentration of refrigerant gas (0-99 units). The bar graph shows the same measurement in steps of 10 units for easy monitoring. The higher the number, the higher the concentration of gas being measured and the closer you are to the exact leak location. Maximum Mode Press MAX ON/OFF >1 second to toggle max mode. When max mode is on, the highest leak size detected is continually recorded. The recorded max is cleared when the sensitivity is changed or if manually zeroed. Sensitivity (H/M/L) DR58 starts up in high sensitivity (H) which is recommended for most situations. When leaks are difficult to pinpoint due to excess triggering or sensor saturation, press SENSITIVITY to cycle to a lower sensitivity (Medium/Low). Mute ( ) Press ZERO and SENSITIVITY simultaneously to toggle the speaker. 13 Red Leak Indicator LED In most situations, the red LED at the tip is easier to monitor than the display. Because the blink rate increases as the relative concentration increases, many leaks can be found without ever viewing the display.
