Typical applications include transformer, motor coil, and PC board resistance measurements.</p></div> <h5><div id="header1">Additional Features</div></h5> <div id="text1" class="a-spacing-small"><p>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.</p></div> <h5><div id="header2">What's in the Box</div></h5> <div id="text2" class="a-spacing-small"><p>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.</p></div> <div class="break"></div><br> <div class="sixth-col"> <div class="centerImage"> </div> </div> <div class="third-col"> <h5><div id="header3">What is a MilliOhm?</div></h5> <div id="text3" class="a-spacing-small"><p>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.</p></div> </div> <div class="sixth-col"> <div class="centerImage"> </div> </div> <div class="third-col last"> <h5><div id="header4">Why are 4-wire connections required when making milliohm measurements?</div></h5> <div id="text4" class="a-spacing-small"><p>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.</p></div> </div> <div class="break"></div> <h4>More Extech Instruments to Choose From</h4> <div class="sixth-col"> <div class="centerImage"> <div id="image3"><img src="https://images-na.ssl-images-amazon.com/images/I/11kaXe+eWYL.jpg" alt="" ><div class="imageCaption">View larger</div></div> </div> </div> <div class="third-col"> <h5><div id="header5">380460 110-Volt Precision Milliohm Meter</div></h5> <div id="text5" class="a-spacing-small"><p>Precision Milliohm Meter has 5 ranges and measures down to 0.1 milliohms using 4-wire Kelvin clip test leads.
