🔬 Revolutionary Smart Detection

Why You Need This:

Smart Features: • Auto Recognition – automatically detects resistor, capacitor, or inductor
• Three Test Frequencies – 100Hz, 1kHz, 10kHz for different applications
• Dual Test Voltages – 0.3V for in-circuit, 0.6V for isolated components
• Live Circuit Testing – low voltage prevents activating semiconductor junctions
• Component Polarity Detection – shows diode orientation automatically
• Data Logging – stores measurements as CSV files for PC analysis


📏 Precision Measurement Ranges

Capacitance Testing: • Range: 1pF to 22mF (massive 22,000,000:1 ratio)
• Accuracy: ±1% typical, ±5% for large electrolytics
• Applications: Timing circuits, filters, power supplies, coupling capacitors
• ESR Measurement – identify faulty electrolytic capacitors instantly

Inductance Testing: • Range: 1µH to 10H (10,000,000:1 ratio)
• Accuracy: ±1% for most values
• Applications: Chokes, transformers, RF coils, switching regulators
• Q Factor Display – assess coil quality and losses

Resistance Testing: • Range: 10mΩ to 10MΩ (1,000,000:1 ratio)
