Variable Displacement Compressor Tester

Model: ECV-600 For A/C with variable displacement compressor, when thecompressor work status is found abnormal, it is necessary toaccurately diagnose whether the fault is the compressor itself,the ECV solenoid or the electronic control system. ECV600 cantest the control PWM signal issued by the electronic controlsystem, and can also bypass the electronic control system todirectly drive the compressor ECV valve, as well as it can test theresistance of the ECV solenoid. Eventually the ECV600 canaccurately determine the fault is the electronic control system,the compressor or the ECV solenoid. This ECV600 can largely reduce repair time and cost, eliminatemisdiagnosis, and avoid the costly repeated repairing. The testeralso has electric protection when battery cable is reverselyconnected by mistake.
