Transformer Ohmmeter

 The 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. It has dual channels with a wide measurement range and can accurately provide 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. 

• Entry level transformer ohmmeter
• 2 channels with max 6 A current output
• ±0.25% measurement accuracy
• 48 V test voltage for fast saturation of transformers
• Multimeter type operation, intuitive and fast
• Safety through automatic, passive discharge circuitry
• True portability – compact size and low weight
