Product Description
Valve tester V2 – OS.111 provides six essential electrical measurements for complete solenoid valve diagnostics:
Operating Current Measurement – Accurately measures the electrical current flowing through the solenoid during operation. Consequently, this measurement identifies valves with excessive or insufficient current draw that could indicate internal resistance problems, coil degradation, or mechanical binding.
Tripping Current Measurement – Determines the precise current threshold at which the solenoid valve actuates. Importantly, this critical parameter affects injection timing and must be consistent across all cylinders for smooth engine operation.
Mechanical and Structural Measurements
Air Gap Measurement (Indirect) – Provides indirect measurement of the air gap in the solenoid valve mechanism. Specifically, air gap variations between cylinders indicate mechanical wear, debris accumulation, improper assembly, or valve seat damage. To address this, the device’s “tapping” function helps eliminate gaps during solenoid valve adjustment.
Electromagnetic Solenoid Testing Properties
Inductance Measurement – Tests the electromagnetic inductance of the solenoid coil, which directly affects valve opening and closing speed. As a result, inductance variations between cylinders cause timing differences in fuel injection, ultimately resulting in uneven engine operation and increased emissions.
Active Resistance Measurement – Measures the DC resistance of the solenoid winding. In turn, this measurement identifies short circuits, open circuits, winding degradation, or connection problems that affect solenoid performance and reliability.
Diesel Injector Safety and Insulation Testing
Insulation Resistance Measurement (V2 Version) – Verifies the electrical insulation between the solenoid winding and the injector body, thereby preventing current leakage that could cause injector malfunction, control unit damage, or safety hazards. Furthermore, the V2 version includes advanced insulation testing with adjustable current and warm-up time for comprehensive insulation diagnostics.
