Coarse Adjustment Trimmer
This adjustment should only be carried out if the probe offset is outside the range
of the zero adjustment dial.
Sensor Head
This clamps the conductor being measured, and carries out the actual current
measurement. It is a precision assembly including a molded component, a ferrite
core, and a Hall effect element. It maybe damaged if subjected to sudden changes
in ambient temperature, or mechanical strain or shock. Care should be exercised
when handing the sensor head.
Opening Lever
Operating lever for opening the sensor head. Always use this lever to open the
