Diesel Common Rail Injector TL200 Piezo Injector Tr Lcr Esr Resistance Capacitance Inductance Tester pump meter valve

The TL-200 (also known as LCR01) is a specialized handheld diagnostic tester for Diesel Common Rail injectors, including both electromagnetic and high-precision Piezo types. It functions as a bridge between basic multimeters and expensive benchtop test equipment, allowing technicians to verify electrical health without a full test bench.
Core Testing Capabilities
The device is primarily used to detect electrical failures in injectors, unit pumps, metering units, and DRV valves by measuring four key electrical properties:
Resistance (
): Detects short or open circuits in the injector coil or piezo stack.
Capacitance (
): Specifically critical for Piezo injectors to measure the charge-holding capacity of the crystal stack.
Inductance (
): Measures the magnetic properties of electromagnetic injector coils.
ESR (Equivalent Series Resistance): Evaluates the internal resistance of capacitors or piezo elements to identify degradation.
