VNTT-PRO tester is designed to perform diagnosis of actuators (electric valves, DC motors) of VNT (Variable Nozzle Turbine) turbochargers. These actuators changes position of turbocharger vanes in the same way as in turbochargers where turbine geometry was changed using vacuum. Apart from testing electronic turbocharger units VNTT-PRO tester can be used to check variable geometry position sensors. These are found in turbines that use vacuum or pressure controlled pneumatic valve to change geometry position. They enable readout of variable geometry vanes opening percentage. The tester is also able to diagnose boost pressure valve operation. VNTT-PRO tester may be helpful in adjusting operating range of variable geometry. The device supports actuators manufactured by HELLA, SIEMENS, MITSUBISHI, SONCEBOZ, DENSO, MAHLE. The range covers significant part of the actuators currently used in automotive industry.
