CHAPTER 3
OPERATION
3.1 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 Use
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.
In order to optimize measurement quality, it is best to center the
conductor in the coil and make the shape of the coil as nearly
circular as possible.
4.
Press the button to turn the instrument on.
3.2.2 Measurement
Read the measurement on the display. The current is given in Arms.
