Page 11: Operation
CHAPTER 3 OPERATION Measurement Principle The flexible sensor is based on the Rogowski coil. This principle combines: • Excellent linearity with no saturation effect (therefore no heating) • Light-weight (no magnetic circuit) 3.2.1 Connection 1. Press the locking clip(s) to open the sensor. 2. Place the sensor around the conductor through which the current to be measured flows (only one conductor in the sensor), then close the sensor. 3. -
