Multimeter UNI-T UT622A

The UT622A LRC is a hand-held component meter - inductors, resistors and capacitors and their secondary properties: D (loss factor), Q (quality factor), Θ (phase angle in degrees), Θ (phase angle in radians) and ESR (equivalent series or parallel resistance). The parameters of the components are measured by alternating voltage with a selectable frequency of 100, 120, 1000, 10000 Hz and a selectable amplitude of 0.1Vrms, 0.3Vrms, 1.0Vrms at the output impedance of the signal source 100Ω. The highest measurement accuracy is 0.1%.
The device has an intuitive TFT LCD display with a diagonal of 2.8 inches and adjustable backlight brightness in ten degrees, a built-in large-capacity Li-Pol battery 1800mAh and a miniUSB connector for charging and data transfer to a PC. The maximum value of the display when measuring primary parameters is 99999 and the minimum value when measuring secondary parameters is 0.0001. Measurement mode - one measurement triggered by a TRI button or a command from a PC; or continuous measurement with adjustable test start speed 20x / sec, 5x / sec, 2x / sec. Configuration of 2 + 1 or 4 + 1 terminals (after purchase of UTR-L100k-H test cables).
Due to its technological sophistication, the device is also suitable for professional use - in conjunction with a computer (PC) it creates a station for sorting components according to specified parameters and is usable in production lines, laboratories, etc.
