Page 5: Warnings And Cautions
Warnings and Cautions The Legend Series Automotive, hereafter also referred to as "the device," is a gas analyzer intended to provide a fast, easy, and accurate means to determine refrigerant purity in refrigerant storage cylinders or directly in air conditioning systems. -
Page 6: General Notices
Thank you for purchasing the Legend Series Automotive Refrigerant Analyzer. The Legend Series Automotive Refrigerant Analyzer is designed for use independently or in conjunction with an SAE J2843 or J3030 approved A/C Service Machine to determine the purity of gaseous R-134a or R- 1234yf refrigerant. We recommend that all personnel who use this instrument read this manual to become more familiar with its proper operation. -
Page 7: Features
Legend Series Automotive Components Legend Series Automotive Base Unit The Legend Series Automotive base unit houses the Full Color Graphic LCD, Infrared Bench, Electrical Connections, and Rechargeable Battery. These components require no maintenance, therefore there are no serviceable components internal to the instrument, and disassembly will void the warranty. - Page 8 The sample hose extensions allow the user to easily connect and disconnect the hose assembly to the analyzer. The extension is connected directly to the analyzer and the sample hose connects to the male feral on the opposite end. Legend Series Refrigerant Analyzer...
- Page 9 If connecting to an approved A/C service machine follow the instructions on this machine to operate the refrigerant analyzer. R-1234yf Tank Adapter Fitting The R-1234yf Tank Adapter Fitting will provide the user with an adapter to allow connection of the R-1234yf Sample Hose to the ½” LH Acme threads on the R-1234yf cylinder. Legend Series Refrigerant Analyzer...
- Page 10 AC Power Adapter The Legend Series Automotive is powered via a Lithium Ion battery. You can also power the unit with the AC Power Adapter which converts a standard 100-240VAC 50/60Hz wall outlet to 12VDC, 1.6A. This AC Power Adapter will also charge the battery when connected to the analyzer.
- Page 11 Failure to follow this caution can result in minor or moderate injury. Hard-Shell Storage/Carrying Case The hard-shell storage/carrying case is custom fit to the Legend Series Automotive. It provides rugged protection for the instrument, as well as convenient storage for all components. The enclosure is general purpose and is not watertight.

Page 12: Operation
First Use The Legend Series Automotive has a built in Lithium Ion battery. Prior to first use charge the battery for a minimum of 2 hours with the included AC Power Supply. The analyzer will function and charge the battery when the AC Power Supply is connected. -
Page 13: Calibration
Calibration Each time the Legend Series Automotive begins a new test cycle it must complete an air calibration. The calibration takes 30 seconds and pulls fresh air into the unit via an internal pump. This fresh air purges any excess refrigerant from the unit to promote accurate test results. -
Page 14: Viewing The Results
Figure 8 Testing Screen Viewing the Results Upon completion of testing, the Legend Series Automotive will display (Figure 9). Disconnect the coupler from the refrigerant source and select ‘Results’ to display the test results (Figure 10). The percentage displayed for each refrigerant indicates the total purity weight of that refrigerant, equaling 100%, with air and non-condensable gases measured independently. -
Page 15: Understanding Test Results
Understanding Test Results The Legend Series Automotive is designed to analyze the base gas it is calibrated for. When testing R- 134a vehicle, R- 134a should be select as shown on (Figure 12). Conversely when testing a R-1234yf vehicle, R-1234yf should be selected as shown in (Figure 13). - Page 16 It is important to note AIR is measured independently of the refrigerant. This means you could have a percentage of AIR present in a sample or refrigerant that totals or equals 100% refrigerant. An example of this is present in (Figure 17) below. Figure 17 Percentage of Air Present Legend Series Refrigerant Analyzer...

Page 17: Maintenance And Troubleshooting
The Legend Series Automotive has a USB update port located on the Back-Panel Connections. This port should not be used for any other purpose other than to install factory updates or when connecting to a certified service cart. -
Page 18: Error Messages
○ Solution: Allow any refrigerant in the atmosphere to dissipate before performing air calibration. ○ Solution: Verify that the air intake and the exhaust are not obstructed. ○ Solution: Verify that the white filter is correctly plugged into the rubber grommets. Legend Series Refrigerant Analyzer... - Page 19 Error #6: The air sensor has expired and must be replaced before the analyzer can be used. Error #7: The gas pressure is out of range. ○ Solution: Verify the SAMPLE EXHAUST port is not obstructed. If an Error message reappears, contact Neutronics or your local service department.
