BC-CR500 common rail tester can test nozzle spray pattern and injector back leakage, 

to check the CR injector with either solenoid or piezo technol CR1000, the repair tester to 
simulate the engine Control Unit (ECU) driving signals for a common rail injector of either 
solenoid technology or piezo technology, made by Bosch, Delphi, Denso and Siemens. 
The user is able to set the control parameters of fuel injection drive signals. 
By combining of a CR1000A tester and a high pressure fuel source, which may be a mechanical manual pump, or an electrical motor driven pump, or a pneumatic driven pressure booster, 
to feed the CR injector, the user is able to fulfill the tasks, such as nozzle spray pattern and 
injector back leakage, to check the CR injector with either solenoid or piezo technology.
 
Design Features
1. Modulated driving signal to ensure the safety of the solenoids of the injectors
2. Injector driving signal Adjustable frequency and pulse width
3. Short circuit protection for solenoid driving signals

4. Rich accessories, ready to test Bosch, Denso and Delphi injectors
