Prediction of current by using Max. magnetic field Hm
The following is the procedure to predict the current necessary for a power amplifier using Max. magnetic field Hm to be applied to a sample. It
can be set independent of a type of an exciting signal.
① Define Max. magnetic field Hm to be applied to a sample and then obtain Max. exciting current i
Turns of a sample or later) using expression (4.13).

If i
m exceeds 6.0[A], this product cannot make measurement. In addition, if the maximum output current of a power amplifier
1
used is exceeded, it is considered that measurement cannot be made under this condition.
Never enter any current exceeding 6[A] in this product. Otherwise, it may fail.
Moreover, do not use the power amplifier exceeding the rated current. Otherwise, it may fail.
