The Extech 380462 represents the 220 VAC version of Extech’s Precision Milliohm Meter series. It’s built to measure small resistances with confidence by employing a 4-terminal Kelvin connection, which effectively eliminates errors from lead and contact resistance. The meter offers five selectable measurement ranges (200 mΩ, 2 Ω, 20 Ω, 200 Ω, and 2000 Ω) with resolutions from 0.1 mΩ up to 1 Ω depending on range. The instrument includes a manual zero adjustment to null out residual resistance and an overrange indication to alert the user when readings exceed the selected range. The large 1999-count LCD aids in readability during testing. The unit comes with 4-wire Kelvin clip leads and is built into a durable housing for field service applications. Features True 4-Wire Kelvin Measurement — Eliminates lead/contact resistance errors Five Measurement Ranges — 200 mΩ, 2 Ω, 20 Ω, 200 Ω, and 2000 Ω Resolution Range — e.g. 0.1 mΩ in lowest range to 1 Ω in highest Manual Zero Adjust — Allows offset correction to zero baseline Overrange Indication — Alerts when measurement exceeds the range Large LCD Display — 0.7 in (18 mm) with 1999 count resolution 220 VAC Powered — Designed for use with 220 V mains (50 Hz) Portable & Durable Construction — Rugged field design with included protective cover Accessories Included — Supplied with 4-wire Kelvin clip test leads Includes 4-wire cables Kelvin clip connectors
