Small resistance meter MMR-620, which ensures high measuring accuracy - the measurement resolution is 1 µΩ. With the use of this device it is possible to perform measurements of objects of both resistive and inductive nature (e.g. testing of transformers or motors). The meter provides a high measuring current for individual subranges and various operating modes, adjusted to the type of measured object - quick measurement mode (3 sec) for testing objects of resistive nature, as well as extended measurement mode for testing objects of inductive nature.
Measure motor winding resistance and other low resistances
MMR-620 microohmmeter enables accurate measurements of both connections resistance (welded, soldered, bolted) and winding resistance of electrical motors and power transformers.
- Measurements of objects resistive in nature:
- welded and soldered connections, equipotential bondings, earthing conductors,
- contacts, welds of rails, conductors and cables,
- measurement according to the four-lead method.
- Measurements of objects inductive in nature:
- motor windings,
- low-resistance coils.
