This is an IC tester for any type of logic chip. The device pules every pin combination and reads the all other pins to find which type of chip it is. The chip would have been already analysed before testing. To read a 28 pin chip would take about 1/2 days and This be is why I made the device be able to select the number pins of the chip to Be Tested. The larger the number of pins the slower ...

The Davis Magnetic Tube Tester consists of an extremely powerful electromagnet which can generate a magnetic field intensity of up to 4,000 gauss, a glass separation tube and a motor driven agitation mechanism. The tube is positioned between the poles of the magnet at an angle of approximately 45 degrees (the angle is adjustable).

07/05/2019 · In 2017, we have published a whole series of articles in which we have described in detail the grinding ball testing procedure. In this article we will briefly list the main points that you should know and work out carefully before starting the tests.. The tests are divided into three types: – laboratory tests are done in laboratory (small) mills.
