Chapter 1 Before Getting Start

■

1.1 Features

● This product is this product to measure various types of physical amount of soft magnetic materials. It is equipped with the signal generator which
can generate both a sine wave and a square wave, excites a sample while automatically increasing a magnetic field value or a magnetic flux
density value gradually until they reach a specified value. When the value is reached, it starts measurement. In addition, not to leave any residual
magnetization in a sample after measurement, it reduces magnetization by automatically applying an attenuation alternating magnetic field.
This product has also features below:
■ By reviewing a sample for a calibration standard, it can make more accurate and more stable measurement than the Iwatsu existing product for
core loss and the like
■ Since the number of pieces of obtained waveform data is 8,192 points/ cycle; i.e. 16 times as many as the Iwatsu existing product, it can
measure coercive force, residual magnetic flux density and the like with high accuracy.
■ It can execute not only sine wave excitation but also pulse excitation (max.: 1 MHz, Duty 50 %, symmetry).
■ Because of Reference function installed, it can compare B-H hysteresis loops which are measured under two different measurement
conditions.
■ Because of two types of cursor measurement functions (Cross and Grad) installed, it can display a measurement value and permeability at an
arbitrary point
■ Measurement data and measurement conditions can be stored in the CSV format with punctuation using tabs and screen hard copy can be
stored in a USB memory in JPEG or PNG format.
■ Measurement data and measurement conditions stored in a USB memory can be recalled to draw the stored data again and to make settings.
■ It has the function to storage setting conditions before powering off and when it starts next time, it uses them.
