Good day. Today I received a package of products. The decade resistor with variable resistance is inoperative in the range x0.1. in the range of 1 ohm shows 0.9 ohm to 2,3,4 is open circuit at 5 is 1 504 kOhm and 6,7,8,9 is open circuit. bad product!!
Product looks ok, haven’t had a chance to use yet. Instructions are in Chinese only, no English unfortunately, but does have diagrams.
