根据手册，关于平滑模式的使用是非常简单的解释。像0000到9999的设置数量提供了许多可能的设置，没有提供一些示例或建议。我有一个AC / DC安培钳（霍尔类型）连接在示波器和数字万用表上，它是Chauvin Arnoux PAC 12.出于某种原因，在10mV / 1A范围内（无论测得的电流），我得到额外的0.3mV的上升电压，这迫使数字万用表的最后几位也可以播放。所以我被迫使用平滑模式，所以要过滤这种不稳定性。通过使用5A DC的负载进行测试，我实际上找到了我需要添加多少平滑，以便从平滑模式获得一些好处。但是我花了四个小时的时间进行测试，通过试验平滑的值和他们的行为或更好的效果。我想从官方频道了解有关平滑模式的更多信息。为了对抗0.3mV的不稳定性，我不得不使用0030样品，这是怎么回事？谢谢。 以上来自于谷歌翻译 以下为原文According to the manual the is a very minimum of explanations about the use of the smooth mode.The number of settings like 0000 to 9999 gives lots of possible settings, with out giving some examples or suggestions.I have one AC/DC ampere clamp ( Hall type) that connects on oscilloscopes and DMM, It is the Chauvin Arnoux PAC 12. For some reason at the 10mV/1A range( no matter the measured current),I get an additional play-up voltage of 0.3mV,that forces the last digits of the DMM to play up too. And so I got forced to use the smooth mode, so to filter this instability. By testing with a load of 5A DC, I managed to practically find, how much smoothing I need to add,so to have some gain from the smooth mode. But it took me four hours of testing, by experimenting with smooth values and their behavior or better, their effect. I would like to know more information about the smooth mode from the official channel.In order to fight back 0.3mV instability I had to use 0030 samples, is this how it works ?Thanks.
