7 Setting and procedure for operation
Follow the procedure below to attach the cable to the target circuit.
1) Slide the lock pin to the arrow
direction.
2) Put the electric wire through
the clamp, and close the
clamp again.
3) Use your finger to hold the
clamp in the full close position,
and push the lock pin until it locks.
 The lock pin is made of metal. If you let it touch electrically charged portions, it may cause electric shock
or device failure or fire. Be careful handling the lock pin.
 Physical impact to the core may cause breakage. It may directly influence the performance. Be careful
handling the core.
 The mating surface on the core is very sensitive. Even a small foreign object on the surface may affect the
measurement performance.
 Excessive force to the core during open clamp may cause breakage.
Incorrect direction may cause inaccurate measurement.
 For both the transfixing wire and the binding band for fixing the sensor,
use the size of W=2.6 mm or less. To fix them together
Put a binding band through a hole for fixing the current sensor, and tie it
with the cable. Do not tie it too tightly.
(Total four holes for fixing the current sensor exist on both sides of the
current sensor).
