Embodiment
Embodiment：A kind of multifunction changable loading automatic test approach, is comprised the following steps that：
Step 1：Test product 2 is positioned on workbench 15, the signal lead of test product 2 and test circuit are connected
Connect；
Step 2：Apply the small pressure of the limit of setting to test product 2 on workbench 15, if now test circuit has conducting
Signal show to conducting display device 17, then discriminating test product is excessively sensitive, if now test circuit without conducting signal show to
Display device 17 is turned on, then discriminating test product is without excessively sensitive bad；
Step 3：Apply the big pressure of the limit of setting to test product 2 on workbench 15, if now test circuit is without conducting
Signal is shown to conducting display device 17, then judges product weight, if now to have conducting signal to show aobvious to conducting for test circuit
Showing device 17, then discriminating test product test is qualified.
The small pressure of the limit set applied to test product 2 is set as the first weight block to the application of test product 2
The big pressure of the fixed limit is that second weight block is superimposed on the first weight block, and first and second weight block 10,11 can be according to reality
Demand is adjusted flexibly, to meet different loading specification requirements.
A kind of multifunction changable loading ATE, including device for exerting, workbench 15 and test circuit, test electricity
