Diesel Common Rail Injector Electrical Tester
Click To Enlarge

Common Rail R-L meter device is used to measure the electrical parameters – resistance and inductance of valves, injectors and solenoids. This tool is suitable for all Common Rail systems including Bosch,Delphi, Denso and Siemens. It is used for more advanced diagnostic on individual electromechanical components by measuring their electrical parameters. To measure the desired parameter of a Common Rail actuator there is no need to remove the component from the electrical circuit. Only one of the two wires to the solenoid actuator must be disconnected before measurement.

Diagnosis of Common Rail solenoid actuators is extremely difficult without the use of this specialized R-L tester, because it is impossible to use an ordinary multimeter for this purpose.
