LCR03 Handheld Tester Meter Capacitor Discharge

LCR03 is a compact handheld tester from Beacon Machine for diesel injector coil validation. It combines six measurement modes including resistance, capacitance, inductance, DC voltage, DC current and DC resistance in a single handheld instrument with 9V battery power.

The tester automatically identifies the type of measurement element and provides accurate measurement results, with a dedicated capacitor discharge protection mechanism that prevents damage from high voltage capacitor short circuits during injector diagnostics on Bosch Denso Delphi Cummins XPI Siemens injector families.

LCR03 covers full measurement ranges from 0.1 ohm to 60M ohm resistance, 1pF to 100mF capacitance, and 1uH to 100H inductance. Four operation keys Power Lamp Hold Mode plus six input terminals provide Kelvin four wire measurement, DC voltage and current test, and safe discharge path for energy storing components before service.

Powered by a standard 9V battery with 200 hours continuous operation, LCR03 is a practical addition to mobile service vans and production lines for EUI EUP HEUI common rail and piezo injectors with capacitor discharge safety.

1. Six measurement parameters L C DCR IA IV DCV in one portable LCR tester - LCR03 combines inductance, capacitance, DC current, DC voltage and DC resistance measurement in a single compact handheld instrument, replacing separate multimeters when validating common rail, EUI, EUP, HEUI and piezo injectors on the workbench.

2. Automatic element identification with capacitor discharge protection - LCR03 detects resistor, capacitor or inductor automatically and discharges high voltage capacitors before measurement, preventing damage to electrolytic capacitors during injector coil diagnostics on Bosch, Denso, Delphi and Siemens common rail systems.

3. Wide measurement ranges covering resistance 0.1 ohm to 60M ohm, capacitance 1pF to 100mF and inductance 1uH to 100H - LCR03 covers the full impedance spectrum for solenoid coils, piezoelectric elements and resistor networks used on Cummins XPI, Caterpillar C9 C12 and Perkins actuator circuits.

4. Integrated LED flashlight and LCD backlight for workshop and field work - LCR03 has a built-in flashlight plus LCD backlight, suitable for dark engine bays, truck chassis undercarriage work and marine engine room diagnostics without external lighting.

5. Four operation keys Power, Lamp, Hold and Mode plus six input terminals LCR plus minus, V/N plus A, A and discharge port - LCR03 provides Kelvin four-wire measurement, DC voltage and DC current test, and safe discharge path for energy storing components before service.

6. Compact handheld design with 9V battery and 200 hours continuous operation - LCR03 weighs about 200g with battery, fits in a tool drawer or service van, and provides reliable testing of EUI EUP HEUI common rail and piezo injectors with capacitor discharge safety for production line use.
