judging whether the overload value meets the preset overload requirement or not, if so, finishing the overload calibration; if not, the left collision air pressure or the right collision air pressure can be adjusted repeatedly until the obtained overload value meets the preset overload requirement.
Therefore, before the trigger delay function of the grenade fuse electronic component is tested, the accuracy of the obtained data in the test process can be ensured by calibrating the front-end operational amplifier proportionality coefficient, the test process data acquisition module and the overload module, and the reliability of the test data is improved.
