FNIRSI Multifunction LCR Transistor Capacitor Tester Resistance 0.01-50Ω

FNIRSI LCR-P1 is a compact, high-precision multifunction tester for measuring LCR parameters, transistor pinouts and basic semiconductor characteristics. It measures resistance in the range 0.01–50 Ω and provides visual readout on a 3.66 cm color display. The device is intended for electronics engineers, technicians and hobbyists who need quick verification of passive components and basic semiconductor parts; it ships with USB and LCR-P1 cables and is specified to operate between 0 and 40 °C.

Advantages

The tester combines multiple measurement functions in a single handheld unit with automatic component recognition and a color display for clear results. Its resistance range from 0.01 to 50 Ω covers common low-resistance checks and the compact design with included USB and LCR-P1 cables supports portable use and easy connection to PC or power. The specified operating temperature range allows reliable operation in typical indoor environments.

Suitable for

• Quick verification of resistors, capacitors and inductors
• Testing transistors, diodes and FETs for basic parameters and pinout
• Bench troubleshooting and component sorting in electronics repair
• Hobby and educational electronics projects

Key specifications

• Resistance measurement range: 0.01–50 Ω
• Display: 3.66 cm color screen
• Operating temperature: 0 to 40 °C
• Included accessories: USB cable and LCR-P1 test cable
• Functions: LCR measurement, transistor and diode testing, automatic component identification

How to use

Connect the tester to the component using the supplied LCR-P1 cable or appropriate test leads, power the unit via its internal battery or USB if supported, and select the measurement mode on the device. For passive components choose the LCR function to read inductance, capacitance or resistance; for semiconductors select the transistor/diode test mode and insert the component leads into the test terminals. Allow the reading to stabilise on the color display before recording results.

Recommendations

Use the tester in a stable indoor environment within the specified 0–40 °C range, ensure component leads are clean and make firm contact with the test probes, and avoid measuring powered circuits. Store the included cables with the device and consult the manufacturer instructions for calibration or firmware updates.
