FNIRSI LCR P1 Transistor Tester Capacitance ESR Meter

Meet the FNIRSI LCR P1 Transistor Tester Capacitance ESR Meter — a high-precision, multifunctional testing device designed for electronic engineers, technicians, and enthusiasts. This handheld LCR tester quickly detects and analyzes transistors, diodes, triodes, and field-effect transistors (FETs) with a 1.44-inch color display that presents multiple parameters at a glance. Its intelligent auto-identification of component type and pin arrangement simplifies operation, boosts testing efficiency, and reduces setup time.

Key safety and convenience features include intelligent anti-burn protection that discharges uncharged capacitors automatically when inserted, safeguarding both your components and the tester. The LCR-P1 supports data export to a computer for easy transfer and in-depth analysis, and its replaceable test boards offer unprecedented flexibility for diverse testing needs. USB-C charging at 5V/1A keeps you powered on the bench, supported by a compact 300 mAh battery for portable use.

Designed to cover a wide range of measurements, the LCR-P1 measures: capacitance from 25 pF to 100 mF, inductance from 10 μH to 1000 μH, resistance from 0.01 Ω to 50 MΩ, and diode parameters including forward voltage < 4.5 V and a dedicated Zener measurement channel from 0.01 to 32 V. It can identify transistors with a gain range of 10 < β < 600, and supports different diodes, including Zener diodes, with independent measurement channels for precise results. It also reads IR codes using the NEC protocol and offers firmware upgrades for ongoing improvements. The device features a 1.44-inch color screen for clear readouts, a 300 mAh lithium battery, and a compact design that makes testing on crowded boards both quick and accurate.

Benefits & Tips

• Fast component identification: Simply plug in a component to automatically identify its type and pin arrangement, saving time on repairs and circuit checks.
• Accurate diode testing: Use the independent Zener measurement channel (0.01–32 V) for precise diode assessment while powering the circuit separately when needed.
• Smart data workflow: Export measurement data to your computer for in-depth analysis, documentation, and trend tracking over time.
