Measurement and application
Flexible DC current measurement requires probe placement to suit the conductor and available space. Use the operating method and connections specified for this product rather than applying instructions for a conventional AC Rogowski coil.
Selection and connections
Confirm the complete probe, supply and output connection before arranging installation and testing.
