这时,再对该器件进行在线功能测试;由于机器人电路板上的其他器件将不会得电工作,消除了干扰作用。此时的实际测试效果将等同于“准离线测试”,测准率将获得很大提高。3.用ASA-VI曲线扫描测试对测试库尚未涵盖的器件进行比较测试由于ASA-VI智能曲线扫描技术能适用于对任何器件的比较测试。只要测试夹能将器件夹住,再有一块参照机器人电路板。通过对比测试,同样对器件具备较强的故障侦测,判断能力。该功能弥补了器件在线功能测试时,要受制于器件测试库不足的约束,拓展了测试仪器对机器人电路板故障的检测范围。现实中往往会出现无法找到好的机器人电路板做参照的情景。而且待修板本身的电路结构也无任何对称性,在这种情况下,ASA-VI曲线扫描比较测试功能将起不到很好的作用。而在线功能测试由于器件测试库的不完备,无法完成对机器人电路板上每一个器件都能测试一遍,机器人电路板依然无法检测下去。这就是的局限。就跟没有包治百病的药一样。
At this time, the online function test of the device is carried out; Since other devices on the robot circuit board will not be powered on, the interference effect is eliminated. At this time, the actual test effect will be equivalent to "quasi offline test", and the accuracy rate will be greatly improved.
3. Use asa-vi curve scanning test to compare the devices not covered by the test library
Asa-vi intelligent curve scanning technology can be applied to the comparative test of any device. As long as the test clamp can clamp the device, there is another reference robot circuit board. Through comparative test, it also has strong fault detection and judgment ability for devices. This function makes up for the restriction that the device test library is insufficient when the device online function test is carried out, and expands the detection range of the robot circuit board fault by the test instrument.
In reality, it is often impossible to find a good robot circuit board as a reference. Moreover, the circuit structure of the board to be repaired does not have any symmetry. In this case, the asa-vi curve scanning comparison test function will not play a good role. Due to the incompleteness of the device test library, the online function test cannot be completed. Every device on the robot circuit board can be tested once, and the robot circuit board is still unable to be tested. This is the limitation of. It's like there is no medicine that can cure all diseases.
