Tektino ECV520i Car Accessories AC Compressor Electronic Compressor Control Valve Testing Tool(Variable Displacement Compressor Tester)

Description

For A/C with variable displacement compressor, when the compressor work status is found abnormal, it is necessary to accurately diagnose whether the fault is the compressor itself, the ECV solenoid or the electronic control system. ECV520i can test the control PWM signal issued by the electronic control system, and can also bypass the electronic control system to directly drive the compressor ECV valve, as well as it can test the resistance of the ECV solenoid. Eventually the ECV520i can accurately determine the fault is the electronic control system, the compressor or the ECV solenoidSpecifications:Power supply: Battery power, 12VDCPower cable length: 2.5MTest cable length: 2.1MConnectors: specific connector 12 pairs (male and female), universal connectors 3 pairs (male and female).Duty cycle range the tester issues: 18%-84%, PWM signals. The bigger the duty cycle is issued, the larger displacement the compressor achieves.Note: Protection against reverse battery connection.
