Abstract

Magnetism is very important for high accuracy class weights. There are several ways to measure magnetism of weights according to OIML R111. In NIM, a new magnetism measure device has been set up to measure magnetism of weights by using gaussmeter. This device compose of a rotation platform, stick pole, control panel , computer and gaussmeter. The gaussmeter is installed on the stick pole. The platform can move horizontally and let the center of the weight just below the probe of the gaussmeter. Also the platform can rotate around and the gaussmeter can detect the largest indication, and the result can be calculated by computer. The support capacity of the platform is 50 kg, so the magnetism of large weight can be measured by this device. The effectiveness of this device is showed by several tests.
