First of all, the lock surface should have a metallic luster, and there must be no obvious scratches. The standby current is about 300 mA, and the operating current is lower than 900 mA. After a long period of power, the surface is slightly hot, but not hot. The force of the electric mortise lock should be sufficient. After the pressure is pressed, the lock can automatically bounce and be powerful. It is best to perform 4,000 times of continuity test. If it is found, the lock is weak during the process, or the bounce is not in place, or the bounce If you don't get up, it is considered unqualified
Some engineering consultants ask: Is it a two-wire or multi-wire electric plug lock? This is the case. The multi-wire electric plug lock is controlled by a single-chip microcomputer. The operating current of the electric lock is controlled by the single-chip microcomputer, and the lock body will not It is too hot, and has a delay control function and a door magnetic detection function; the delay control function can be adapted to the use of a door with a bad spring, and the door magnetic monitoring function can provide a real-time monitoring function of the door opening and closing state for the controller. Although these functions are not necessarily used, the quality and stability of the electric locks controlled by the single-chip microcomputer and the electric lock without the single-chip control are not at one level. Therefore, it is recommended that you do not have to save a little money, the two-wire electric plug lock, the internal structure is very simple, just a mechanism that drives the electromagnetic coil, the working current is large, and the heat is severe enough to damage the electric lock at a certain time.
