MEASUREMENT DIRECTION OF THE ROTATING MAGNETIC FIELD
It is necessary to measure the direction of the rotating magnetic field in the following
way:
• Insert terminals L1, L2 and L3 of the test pen into the L1, L2 and L3 holes
respectively.
• Insert the other terminal of the test pen into the alligator clip.
• Allow the alligator clip access to the phases of the three power cables to be
measured.
• Afterwards, the LCD will automatically display the sequence of L1, L2 and L3.
