Product Description
Battery Powered Milliohm Meter
Battery operated to facilitate in-the-field use, Extech's 380580 Milliohm Meter provides five resistance ranges with resolution as low as 0.1 milliohms, and the 4-wire Kelvin clip connection provides optimum accuracy. Typical applications include transformer, motor coil, and PC board resistance measurements.
Additional Features
Measurements are displayed on a large, 2000 count LCD. Additional features include over-temperature and over-voltage protection, Auto-Hold, Auto power off, and invalid test indicators to prevent inaccurate measurement.
What's in the Box
Unit is housed in a built-in water resistant case and comes with eight AA batteries, two sets of test leads (4-wire with four alligator clips and 4-wire with two Kelvin alligator clips), and user manual.
What is a MilliOhm?
The units of measure for resistances less than 1 Ohm (Ω) are Milli- (mΩ) and Micro-(μΩ)Ohms. One MilliOhm (1mΩ) is equal to one thousandth of an ohm (0.001). One MicroOhm (1μΩ) is equal to one millionth of an ohm (0.000001). For example, 0.5 ohms (one half an ohm) is equal to 500mΩ.
Why are 4-wire connections required when making milliohm measurements?
Test leads always introduce a small amount of additional resistance into a measurement. This is acceptable in non-critical measurements such as megohm resistances. However, when measuring milliohms in a critical application, any additional resistance can render the measurement useless. This is why 4-wire (Kelvin) connections are imperative.
