The UT622A is a handheld LCR meter for component measurement in the field, on the bench, and in teaching settings. It measures inductance, capacitance, resistance, impedance, ESR, and D/Q at test frequencies of 100 Hz, 120 Hz, 1 kHz, and 10 kHz with 0.1% basic accuracy, using a 4-wire Kelvin connection for clean low-impedance readings.
Capacitance reads from 0.00 pF to 99.999 mF, inductance from 0.00 µH to 99.999 H, and impedance from 0.0000 Ω to 9.9999 MΩ. Selectable test signal levels, series and parallel equivalent-circuit modelling, open/short correction, auto-ranging, and tolerance sorting support measurement and component grading.
It suits electronics technicians, QC, and instructional use needing portable component characterization.
