เครื่องทดสอบสะพานดิจิทัลแบบมือถือ ทดสอบความจุ ความต้านทาน และเหนี่ยวนำ, FNIRSI LC1020E

1. Automatically identify components, automatically select based on component characteristics, making the measurement process more convenient and efficient
2. Multiple frequency tests, effective value test levels. Supports five test frequencies: 100Hz, 120KHz, 1kHz, 10kHz, and 100KHz. It is suitable for the measurement requirements of different application scenarios. With effective value test levels of 0.1V, 0.3V, and 0.6Vrms, the measurement results are more accurate and reliable
3. Four-segment digital display, with high precision, capable of simultaneously showing main and auxiliary parameters
4. Internal bias function, eliminating material nonlinearity, restoring true capacity, enabling precise measurement and control of nonlinear components, weak signals, or complex environments
5. One-click locking and recording, making measurement more efficient. Press lightly to lock the current reading, press for a long time to activate the recording mode. The test results are classified and statistically analyzed in real time. The measurement is accurate, clear to view, and the detection efficiency is doubled. It enables you to easily control each measurement
6. Five test scenarios, supporting precise measurement of capacitors, resistors, inductors impedance, electrolytic capacitors, etc
7. Compact handheld design, allowing for precise measurement anytime and anywhere
8. Open circuit/closed circuit correction function, used to eliminate systematic errors introduced by test fixtures and cables, which directly affect the accuracy of the measurement results
