note 1: Reference measurement position of the conductor. Maximum
coupling diameter: 20 mm for published accuracy.
note 2: Keep minimum 65 mm to ensure published accuracy.
6. Ensure the coupling point of the flexible measuring head is firmly locked.
7. Press RANGE button to select any desirable range (300A/ 1000A/ 3000A).
When powering off the instrument once and powering on again,
the range will be the same one selected prior to powering off the
