The MTO106 provides two test channels and manually selectable test currents in five steps up to a maximum of 6 A. Measurement accuracy is to within ±0.25%. An open-circuit test voltage of up to 48 V ensures that even large transformers are saturated rapidly, reducing test time. The unit is supplied with long test leads fitted with Kelvin clamps that allow for testing pole-mounted transformers.

Audible and visual indicators alert users that a test is being conducted. At the end of the test, the winding is automatically discharged, even if the supply to the instrument is turned off. The MTO106 carries out winding resistance measurements in accordance with most major transformer testing standards, including those set by CIGRE, IEEE, IEC, and ANSI.

Prices for the MTO106 transformer ohmmeter start at $6882.
