我在用keithely2306模拟电池功能测量一款充电器充电电流时,发现labview测试出来的电流比直接接上锂电池用万用表测试出来的电流要低10MA左右,试了不少方法都没有改善,请问问题会出在哪里呢?具体是我要测试的电流值在70ma左右,用2306仿真为1。4V电池,然后充电器对其充电,再在2306中读回电流值,是我的2306设置有问题吗,谢了

不同型号的锂电池VA特性曲线会有略微差异。Keithely的仪器只是模拟锂电池的VA曲线,所以有偏差是可以接受的。LabVIEW采集到的模拟电池VA值都是仪器的测量值,应该和仪器前面板液晶显示器上的读书一致。如果这两个值不一致,那是LabVIEW 的仪器驱动有问题。
