Fitted to the exposed spindle was a unique "screw-cutting dog clutch" that, the makers claimed, allowed " even those without previous experience cut any thread easily and quickly "- if only the generation of good-quality threads were so simple; however, in the sense that it was impossible to "pick up" a thread at the wrong point and spoil a job, the device did work efficiently - and was well received by experts at the time (the headstock was considered well enough engineered to be adopted as the basis for an ingenious multi-function machine tool the " Metalmaster "- the details of which make fascinating reading).

安装在暴露主轴是一个独特的&螺旋切割狗离合器&这一点，制造商声称，允许&，甚至那些没有以往的经验削减任何线程轻松和快速地&-如果只产生高质量线程是如此简单的；然而，在这个意义上讲，是不可能的&拿起&一个线程在错误的点和破坏工作，该设备也提高工作效率-，并且受到专家们的时间（在启闭被认为不够好工程要通过为基础，设计精巧的多功能机床的& Metalmaster &-的细节，这使得迷人读）。

Through the analysis about the measure data of three-phase, four wires electric meter in the different modes, we can know that whether the electric meter is connected to earth wire or not, the error is different.

本文通过对三相四线有功电能表在不同方式运行中的计量分析，可以知道接入零线与未接零线在运行中出现同样故障时，其计量的误差不同，会造成计算错误。
