The function of the tester for CR high pressure pumps is to provide the desired signal to drive the solenoid in the pump being tested. CR2000 common rail Tester can used for testing following pumps: BOSCH CP1-H, BOSCH CP1-K,BOSCH CP3, DELPHI, DENSO HP2 AND HP3. It also can test 6 common rail injectors in one time. Design Features 1Modulated driving signal to ensure the safety of the solenoid of the CR pump 2Adjustable duty cycle for the driving signal 3Short circuit protection for the output circuitry of the solenoid driving signal 4Measure and LCD display rail pressure 5The tester model for Denso U2 pump inputs and processes the signal from pump speed sensor on the U2 pump, and ensure the driving signal synchronous with pump speed.
