2.2.1. Connection
First of all, use the appropriate means of protection.
• Press the yellow opening device to open the flexible coil.
• Open it, then place it round the conductor through which
the current to be measured flows (only one conductor in
the sensor).
• Close the coil.
In order to optimize measurement quality, it is best to
centre the conductor in the coil and to make the shape of
the coil as nearly circular as possible.
• Press the
lights.
2.2.2. Measurement

given in Arms.
If the measurement exceeds the display capacity (400 A),
