Usage Notes
CAUTION
• When opening the sensor head, always operate
the opening lever. Subjecting the sensor head
to force from the directions shown in the figure
while it is locked may damage the clamping
mechanism.

• Keep the sensor head closed when not in use,
to avoid accumulating dust or dirt on the facing
core surfaces, which could interfere with clamp
performance.
• The sensor head is a precision assembly
including a molded component, a ferrite core,
and a Hall effect element. To prevent damage,
avoid abrupt temperature changes, mechanical
shock, static electricity, and other problematic
phenomena.
• The matching surfaces of the sensor head are
precisely ground, and should be treated with care.
If these surfaces are scratched, performance may
be impaired.
• Lock the sensor head while the POWER LED is
on (except when clamping the conductor being
measured). Leaving the sensor head open may
damage the device.
