UNI-T UT622A

The UT622 series offers high performance, handheld component measurement devices (LCR meter) that measure inductances, resistances and capacitors, as well as their secondary parameters D (dissipation factor), Q (quality factor), Θ (phase angle in degrees), Θ (phase angle in radians) and ESR (series or parallel equivalent resistance) can be measured.

The parameters of the components are measured by an AC voltage with a selectable frequency of 100, 120, 1000, 10000 or 100000 Hz and a selectable amplitude of 0.1 Vrms, 0.3 Vrms, 1.0 Vrms measured. The output impedance of the signal source is 100 Ω. The maximum measurement accuracy is 0.1 %. All measurements can be accurately displayed on the instrument's 2.8" TFT LCD display.

The UT622 devices are perfect for professional users who are looking for a high-quality and accurate LCR meter (component tester). They comply with all EU safety standards.

Power suppl

Power supply mode: The UT622 series have two power supply methods: lithium polymer battery power supply and USB power adapter power supply. Between the two power supply modes, the instrument can automatically switch the uninterrupted power supply mode based on the principle of external power priority. The UT622 series can be connected to an external USB power adapter via a MiniUSB charging cable for power supply and charging, or directly connected to a computer USB port via a MiniUSB cable for charging and communication.

Test ports

Supports three-terminal simple test, endless end-face test and Kelvin test line expansion. Allow both convenient testing and high-precision testing requirements.

• Complete five-terminal

• Convenient three-terminal test hole
