The MTR105 is a special static engine tester with the proven range of Megger insulation resistance (IR) tests and the excellent classic functionality and reliability of the Megger test equipment.The MTR105 performs the test functions of the proven Megger IR test equipment. In addition, it convinces with the following test functions: DLRO four-wire measurement (Kelvin measurement in the low-ohm range), inductance and capacitance, in order to provide a versatile motor tester. All this is combined in MTR105 a compact form in a rugged, portable device that has never existed before.In addition, the MTR105 has a temperature measurement and compensation function (for IR tests) and a function for checking the direction of rotation and the phase rotation of the power supply.With these new test features, the MTR105 is a practical, versatile, portable engine tester.This text is machine translated.
