這時，再對該器件進行在線功能測試；由于機器人電路板上的其他器件將不會得電工作，消除了干擾作用。此時的實際測試效果將等同于“準離線測試”，測準率將獲得很大提高。3.用ASA-VI曲線掃描測試對測試庫尚未涵蓋的器件進行比較測試由于ASA-VI智能曲線掃描技術(shù)能適用于對任何器件的比較測試。只要測試夾能將器件夾住，再有一塊參照機器人電路板。通過對比測試，同樣對器件具備較強的故障偵測，判斷能力。該功能彌補了器件在線功能測試時，要受制于器件測試庫不足的約束，拓展了測試儀器對機器人電路板故障的檢測范圍?，F(xiàn)實中往往會出現(xiàn)無法找到好的機器人電路板做參照的情景。而且待修板本身的電路結(jié)構(gòu)也無任何對稱性，在這種情況下，ASA-VI曲線掃描比較測試功能將起不到很好的作用。而在線功能測試由于器件測試庫的不完備，無法完成對機器人電路板上每一個器件都能測試一遍，機器人電路板依然無法檢測下去。這就是的局限。就跟沒有包治百病的藥一樣。

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.
