When the motor comprehensive test equipment is used daily, point inspection needs to be carried out every day or at regular time so as to ensure that the test equipment is in good condition and can work normally. When the motor comprehensive testing equipment is actually used by many enterprises, due to the fact that no appropriate point inspection device of the motor comprehensive testing equipment is provided, daily point inspection is not selected, and therefore the motor comprehensive testing equipment can not be found in time when faults occur. Along with the increasing development of the motor industry, more and more certification standards clearly stipulate that related pressure resistance and other test equipment need to be subjected to daily point inspection, and a convenient, practical and accurate point inspection device can be widely applied.

At present, the existing methods for detecting the comprehensive motor test equipment mainly comprise 3 methods, one method is that part of enterprises take annual or regular test equipment measurement as the only mode of the test equipment, and the point inspection is not carried out in the daily use process; the other method is to use the existing point inspection box or point inspection device with single partial function to perform point inspection; in addition, few enterprises perform daily point inspection by detecting qualified motor samples which are selected.
