觉得MM的万用表非常多,总是见一个爱一个,远远满足不了她的需求。
我手上万用表就两三个,最喜欢用带开关那只,不用时按开关得了,不用啪啪啪打档关表。
顺祝MM新年快乐!元旦快乐!

档位忒多,外观有点呆,做工将就。众仪可以借鉴迈斯泰克,稍“好”一点的表用硬封

snowrose2000:奇葩么?没觉得啊。 (2019-01-01 10:07) 回 snowrose2000 的帖子

正常测量是知道要测量的参数不知道测量值,手动挡要预估或高档位试测,频繁换挡不方便,所以后来出了自动挡,对于偶尔需要手动量程的情况搭配个按键的设计就够了,但要自动到替人自动选择测量参数就没必要了,电路千变万化这种自动选择经常出错。这表融合了最保守和最激进的档位设计还不奇葩么。

在我熟悉的专业从事电子或电工人中,有少数选择手动量程的,但从没有用全自动的。

这款好象自己不能校准了?还有自动识别档位上,直流电压最低多少能测,比如0.5V?
