The device "CR4 Tester.PR" allows to test the diesel electro-controlled injectors of the Common Rail system, giving the user-defined necessary injector control signals and fuel pressure, by controlling the control valve.
Pressure control is carried out only by the standard high-pressure regulator installed on the rail, or on the CP1 pump.
When using a CP3 pump, it is necessary to install a rail with a high pressure regulator from the CP1 system. The “CR4 Tester.PR” device does not automatically control the CP3 pump low pressure regulator. All control of the device is carried out using the control buttons and multi-turn switch.
CR4-Tester is used in CR-JET4-M and CR-JET4-E diagnostic test benches for testing CommonRail injectors manufactured by Bosch, Delphi, Denso, Siemens with system pressure up to 2400 bar.
