[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

The plurality of test stations are respectively a DC reference voltage test station 9, a residual voltage test station 10, a forward square wave test station 11 and a square wave reverse test station 12. A coding station 13 is arranged behind the test stations inside the test box 2, and an audible and visual alarm 15 is installed on the top of the test box 2.

[0020] Through multiple test stations, multiple parameters of the resistor can be tested at the same time. During the test, if the product is unqualified or damaged, the status will be stored and subsequent tests will be automatically skipped. The coding station 13 will not perform coding operations on unqualified products, and the sound and light alarm 15 will sound an alarm to serve as a warning.
