Beyond the full AC LCR set, the UT622E measures DC resistance from 0.01 mΩ to 20 MΩ. Reading DCR alongside impedance and ESR characterizes windings, contacts, and low-value components more completely than an AC-only meter — a meaningful step for power-electronics work.

A 4-wire Kelvin connection separates the drive and sense paths so lead and contact resistance don't corrupt the reading — essential for low-impedance components where milliohm-level errors matter. Open and short correction nulls fixture and lead effects before a measurement run.

Beyond L, C, and R, the meter reads impedance (Z), equivalent series resistance (ESR), dissipation factor (D), and quality factor (Q), with series or parallel equivalent-circuit modelling and impedance phase from −179.9° to 179.9° — the parameters needed to characterize a part, not just read its nominal value.

A tolerance-comparison function sorts parts pass/fail from 1% to 20% bands at up to 20 measurements per second, suited to incoming inspection and small-batch QC. Results log to 500 groups and transfer over USB.

A 2.8-inch color display and a rechargeable Li-polymer pack good for about 8 hours make the UT622E a capable bench and lab instrument that travels.

DC resistance (DCR) measurement from 0.01 mΩ to 20 MΩ, alongside the same 100 kHz AC LCR capability.

DCR characterizes windings, contacts, and low-value parts at DC, complementing the AC parameters for a fuller picture.
