The LD9-TG features sensor technology designed to detect a 5% hydrogen / 95% nitrogen tracer gas mixture. The LD9-TG’s full color liquid crystal display (LCD) and sweep mode function convey messages, graphics, and prompts to help the A/C technician locate the source of a leak and ensure that the leak detector is always at optimal performance. The light-emitting diode (LED) inspection lights aid the technician in locating and inspecting suspected leak sources. When used with the hydrogen/nitrogen tracer gas mixture, the LD9-TG will detect leak rates equivalent to 4 g/year of R-134a in the High setting, and 7 g/year in the Normal setting while moving at 3 inches (8 cm) per second. This complies with SAE J2970 sections 7.2 and 7.3. Testing with tracer gas also complies with European standards EN 35422 and EN 14624.
Once a leak is detected, the leak size indicator bar graph will display on the detector screen. The number of bars will increase or decrease depending on the amount of tracer gas detected. The maximum value of the tracer gas will be displayed once the leak source has been located. Refer to the table below to determine the approximate size of the leak.
Turn on sweep mode by pressing the MODE button. This mode allows the user to pinpoint hard to find small leaks. The display cursor will sweep across the display from left to right tracking a horizontal baseline over a 3 second period. When no tracer gas is detected, the display cursor will be flat. If tracer gas is detected, the cursor on the display will rise up and continue to rise as the leak source is approached. If the detector moves away from the leak source, the cursor will drop back down. NOTE: The default sensitivity level in the sweep mode is High.
