Chapter 1 System Overview 1.1 Overview DX-320HC Coercimeter is specialized in measuring the coercivity of soft magnets. The measured samples are soft magnets with shape of strip, bar and sheet, and magnetic components such as relay, electromagnet valve, magnetic head and so on. It can visually evaluate the magnetic change of magnetic components during the workmanship(such as electroplating, annealing and welding); and also be used for magnetic measurement of magnetic label, magnetic anti-forgery ink and cemented carbide. DX-320HC Coercimeter adopts vibration sample zero flux detection sensor,...

Excitation magnetic field Input the magnetic field to be measured with an accuracy of 0.01. Select the estimated range of coercivity for the sample to be tested (0-50, 50-500, 500-5000, 5000-50000) Test times Select the number of times (1-100) to measure this set of conditions Dual end measurement mode When it is necessary to measure the coercivity of the sample in different directions, check the double ended measurement option; After the user selects the option, the system will prompt the user to turn the sample after measuring the coercivity of the first end. The user needs to turn the sample...

Magnetization holding time: Stable magnetization time Pre magnetization mode: When turned on, it will demagnetize first and then test, and when turned off, it will test directly. Solenoid constant: cannot be changed, bound to the testing platform; After selecting the corresponding test settings, click the "OK" button to take effect Select the coercivity unit to be displayed Enter by clicking the history button on the first interface. In this interface, first select the time to be measured, then select the relevant data in the number, batch number, tester, and remarks (all empty means full search),...
