Description

TECHNICAL FIELD

[0002] The following matters should be paid attention to when using the magnetic metal detector: 1. The magnetic metal detector is not suitable for detecting samples with high moisture content and serious caking; 2. The detection test should be carried out in a well-lit physical laboratory; 3. The operation table should be kept clean and stable, away from water sources, chemical tests and high-precision electronic instruments, and ventilation should not be carried out during the test; 4. Before the test, the magnetic metal detector should be thoroughly cleaned with dry gauze or a small brush, the power supply should be connected to check whether the instrument is running normally, and then the sample should be poured; 5. During the test, the flow rate of the sample is too fast or too slow, which will affect the test results, in order to avoid the loss of magnetic metal, the white paper containing magnetic metal and residual sample mixture should be placed flat on the strong magnetic area of the separation plate for storage and waiting for separation, and the number of repetitions of different types of magnetic metal detectors is slightly different, so the number of repetitions should be based on the fact that no magnetic metal can be seen.
