Fault Differentiation: When the air conditioner reports a compressor fault, directly drive the compressor with a diagnostic tool. If it starts and runs normally, the fault lies in the air conditioner's mainboard/drive module; if it fails to start, makes abnormal noises, or has abnormal current, the compressor itself is . Performance Testing: By adjusting the frequency, test the compressor's operating status at different speeds to determine if there are problems such as cylinder jamming, winding short circuits/open circuits, or phase loss. Repair Assistance: After repair, the compressor can be directly driven for testing without reinstalling the entire air conditioner, significantly reducing rework and repair time. Multi-model compatibility: Not limited by air conditioner brand, it supports most 1~5 horsepower household/commercial inverter air conditioner compressors on the market, making it a universal tool for repair technicians. Never plug or unplug compressor terminals or equipment wiring while the circuit is energized. Single continuous test sessions should not be too long Wiring must be secure and reliable. for specialized compressors with proprietary encryption protocols are not supported. This is a universal inverter air conditioner compressor tester for 1-5HP models. It is a core tool for repairing small and medium-sized inverter air conditioners for both residential and commercial use. Compared to the 1-3HP model, it supports a wider power range and can directly drive and test the status of the inverter compressor without the air conditioner's mainboard. It can quickly distinguish between "mainboard failure" and "compressor failure" and is suitable for repairing 1-5 HP residential and small commercial inverter air conditioners.Name: Frequency Conversion Compressor Tester Voltage: AC200-240V Testing Type: 1-5HP Function: For Testing variable frequency Air conditioner compressors Plug Type:EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so
