Introduction; Purpose; General Provisions - Open System Mega Tester V4 Technical Description And Instruction Manual

Warning!!! This device contains dangerous voltage, please read this manual
carefully before using it.
This passport is a document certifying the main parameters and technical
characteristics of the device for testing the electrical parameters of piezoelectric
diesel injectors of the Common Rail system, Mega Tester V4 OS.110 V4, guaranteed
by the manufacturer. This passport allows you to get acquainted with the device
structure, procedure and rules of its operation, compliance with which will ensure
correct operation and long service life of the device.
The device for checking the electrical parameters of piezoelectric diesel
injectors Mega Tester V4 OS.110 V4 (hereinafter referred to as Mega Tester, device,
instrument) is designed to check the integrity of the piezoelectric element insulation,
measure its capacitance and resistance, and check the correctness of its operation.
The Mega Tester is a hardware and software system that allows you to
measure the capacitance of the piezoelectric element, measure the resistance of the
piezoelectric element under voltage, measure the insulation resistance under high
voltage, and generate the injector control voltage to measure the stroke of the
piezoelectric element and the gap between the piezo actuator and the pusher of the
injector hydraulic valve. The functionality of the device allows you to assess the
degree of wear of the piezoelectric element, and is designed to facilitate the diagnosis
and defecting of piezo nozzles, as well as help to assess the correctness of the nozzle
assembly.
The device is controlled from a computer using the keyboard and mouse. It
is also possible to start the device manually using the buttons on the front panel.
Some functions are not available in the device menu.
