这个东东先驱们早有说过，从上面的PTM File Id = B1流程测试模块文件ID是B1,PTM Test Id = 4E0流程测试模块测试ID是4E0，也就是WDR软件的中文版的伺服校验按钮，英文版是PS Cal Test这个按扭。有时我们出盘会全盘叹号，（自校日志绝对不可以清）有时清译码再重建P表不能解决的，可以清译码-重启-PS Cal Test-完成后重启-重建P表试下。这个PS 是个缩写，不确定是不是 Positioning signal定位信号的意思，还是phase shift相位偏移的意思或其它。做了它后flash的4F会改变，4F各个软件说法不一，我本人更原接受宏代码版本这个说法，因为其专利文件也常提到  宏脚本，修正后解码器才能正确识别。当然这纯属我个人见解，或许就是个谬论。
