Bridge Measurement Technology Advantages
True 4-wire bridge measurement eliminates lead resistance errors that plague basic component testers. This professional architecture—identical to £1000+ bench LCR meters—provides accurate milliohm measurements and reliable in-circuit testing at 0.3V to prevent semiconductor activation.
Comprehensive Component Analysis
Capacitor Testing: Measure capacitance from 1pF to 20mF with ESR and dissipation factor. Identify failing electrolytic capacitors in power supplies before complete failure through ESR analysis across multiple frequencies.
Inductor Characterization: Test inductance from 1µH to 60H with Q factor and series resistance measurements. Assess coil quality, winding resistance for power calculations, and frequency response across the operating spectrum.
Precision Resistance: 4-wire Kelvin measurement technique provides accurate readings from 1mΩ to 10MΩ, ideal for contact resistance verification and PCB trace testing.
Diode Testing: Automatic polarity detection with visual indication. Measures forward voltage from 0.1V to 16V regardless of probe orientation.
