UNI-T UT622C LRC multimeter

The UT622C LRC is a handheld component tester for coils (inductance), resistors (resistance) and capacitors (capacitance), as well as their secondary characteristics: D (dissipation factor), Q (quality factor), ? (phase angle in degrees), ? (phase angle in radians) and ESR (equivalent series or parallel resistance). Component parameters are measured using an AC voltage with a selectable frequency of 100, 120, 1,000 or 10,000 Hz, 100 kHz and a selectable amplitude of 0.1 Vrms, 0.3 Vrms, 1.0 Vrms at a signal source output impedance of 100 ?. The highest measurement accuracy is 0.1 per cent.
The instrument features an intuitive 2.8-inch TFT LCD display with ten-step adjustable backlight brightness, a built-in high-capacity 1,800 mAh Li-Pol rechargeable battery and a mini-USB connector for charging and data transfer to a PC. The maximum display value when measuring primary parameters is 99,999 and the minimum value when measuring secondary parameters is 0.0001. Measurement mode – single measurement triggered by the TRI button or a command from a PC; or continuous measurement with an adjustable test rate of 20x/sec, 5x/sec or 2x/sec. Terminal configurations: 2+1 or 4+1 (with UTR-L100k-H test cables, which are included with this instrument).
Thanks to its technological sophistication, the instrument is also suitable for professional use – when connected to a computer (PC), it creates a workstation for sorting components according to specified parameter tolerances and can be used on production lines, in laboratories, etc.
