Opening Lever
Operating lever for opening the sensor head. Always use this lever
to open the sensor head.
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
may be damaged if subjected to sudden changes in ambient
temperature, or mechanical strain or shock. Care should be
exercised when handing the sensor head.
Demagnetizing Switch (DEMAG)
This demagnetizes the core if it has been magnetized by switching
the power on and off, or by an excessive input. Always carry out
demagnetizing before measurement. The demagnetizing process
takes about one second. During demagnetizing, a demagnetizing
waveform is output. Refer to “Demagnetization and Zero
Adjustment” on page 16.
