This new Injector Tester has developed in order to improve diagnostic efficiency and 

accuracy  for Common Rail System in the vehicle.

Enables Injection Amount Comparison Test under Low and High fuel pressure conditions 

that was not possible with GDS/G-Scan . 

Also Cylinder compression and Rail pressure regulator test are additionally available.
