Description
Use
The MMR-650 instrument is designed to measure very small resistances of windings, including transformers with amorphous Kern, as well as resistive objects. This product is intended for use in power plants, railways and maintenance companies for measurements such as:
• Transformer and motor windings,
• Electrical protective devices, screw connections, welding connections
• Earthing connections, equipotential bonding,
• Welding and solder connections,
• Screw connections
• Other resistive and inductive objects.
The MMR-650 can also be used on production lines (e.g. during the production final inspection).
Device functions
The MMR-650 instrument for winding resistors and low resistance resistors offers an innovative combination of a high performance instrument with a modern user interface and an advanced data management system. The wireless data transmission, the improved 2DCode system and the possibility to print labels for the identification of the test specimens contribute to a new quality of work and enable the user to carry out a variety of measurements.
Easy to read
The measuring device is equipped with an easy to read color touch-screen. The resolution of 800 x 480 pixels ensures convenient use of the interface as well as good readability of the results of measurement.
Robust and practical housing
The MMR-650 microohmmeter has been developed to meet the needs of customers for operation under difficult environmental conditions. A unique housing with the protection class IP67 ensures that the device
is water- as well as dust-proof.
