The inner\ndiameter of the hole at the bottom of the original coil is: approx. 13 ± 0.5\nmm \/ 0.5 ± 0.02 inches. The height of the round hole at the bottom of the\noriginal spool: approx. 60 mm \/ 2.4 inches. The diameter of the hole at the\nbottom of the secondary coil is: approx. 35 ± 1 mm \/ 1.4 ± 0.04 inches. The\ninner diameter of the circular hole at the bottom of the secondary coil is:\napprox. 49 ± 1 mm \/ 1.9 ± 0.04 inches. The height of the round hole at the\nbottom of the secondary coil: approx. 80 mm \/ 3.1 inches. Soft core length:\napprox. 85 mm \/ 3.3 inches. Package list: 1 x primary coil A. 1 x secondary\ncoil B. 1 x soft iron core C. Note: 1. Since the DC resistance of the original\ncoil is very low, the current must not be too large, the switch-on time should\nnot be too long and the supply voltage should not exceed DC4V. 2. Be sure to\nprotect the plastic frame and do not expose it to strong bumps or fall on the\nfloor. 3. After the instrument has been used, it should be placed in a clean,\ndry and ventilated place without corrosive gases. 4. Please note that the new\nand old type of this product will be sent at random.
