MEGGER MTO106 transformer ohmmeter is an easy-to-use, line-operated instrument specifically designed for safe and accurate field measurement of winding resistance in smaller transmission and distribution transformers. Device has dual channels with a measurement range and accuracy suited to provide accurate information about the vast majority of power transformers, reactors and instrument transformers. The test current can be manually set in five different ranges to fit transformers of various sizes. Unit has a single selector switch for test current and a single button to activate the test cycle and is also supplied with test leads fitted with Kelvin clamps that allow for a single, one-time connection to the unit under test.
