小白翻译第四篇：万用表的第三只手
说之前为了混块坛主家的众仪万用表尝试着翻译了三篇万用表相关的文章，结果坛主大人还就真的给了我个名额，并最终由@版主5448赠了我一块精心收藏的全新的众仪ZT219。收到表后很开心，在这里再次感谢一下@坛主43545和@版主5448，众仪电测，仪表爱好者论坛。
不过表一到手就开始缺乏继续努力的动力了，收到表后这么些天也没再为论坛做啥贡献，想一想这样多不好啊，于是就再硬着头皮翻译点啥为论坛添一块小瓦片吧:lol
之前翻译的几篇得到了不少坛友的支持，也收到了很多中肯的意见与建议。之前基本上是直译，很多坛友反应过于生硬、晦涩、难懂。。。此处省略一万字。所以这次尝试改一改风格采用意译来试一下，可能会因此导致词句与原文对应不上，但应该不影响理解。
上一篇翻译的东东在这：小白翻译第三篇：RMS 与 True RMS万用表的区别
还是那句话，本人小白，没有专业知识打底，翻译的过程也是学习的过程，翻译得不一定准确，望大神们不要轻易打我:loveliness:
THIRD HAND FOR YOUR MULTIMETER 万用表的第三只手
You often need more hands for jobs with your multimeter than the normal body is equipped with, if you are an insect or octopus, or do not use a meter much, then this instructable will be unneeded by you, if you are human and do much electronics work, I think it will help you out.
你用万用表时是否经常发现手不够用？如果你是只6足小强或是条8爪章鱼;P，再或者你平时不怎么用万用表的话，那么这篇教程对你的价值或许不大。但是如果你是人类并且经常做一些电子类相关的工作，那我敢说这篇教程对你的帮助可就大了去了。
Step 1: Tools and Materials 第一步：工具与原料
Scraps of hardwood 硬木板
Bit of metal sheet ( copper or brass is particularly nice ) or piece of un-etched circuit board 金属板少许（紫铜/黄铜尤佳）或一片没有经过蚀刻的电路板
Set of binding posts 接线柱一组
2 alligator clips 鳄鱼夹两个
Ribbon cable connector from an old computer 旧电脑上的软排线一条
Bits of wire 电线少许
Hot glue gun 热熔胶枪一把
Saw and drill 锯、钻各一把备用
Soldering iron 烙铁一把
Step 2: Building the Base 第二步：制作底座
I used 2 small pieces of oak for the main base and body of this gadget. None of the measurements are critical, plan it out yourself. Two holes are drilled for the binding posts, and 2 for the alligator clips. These are both in the upper part of the base, the lower part has 2 holes to get at the back side of the binding posts. Make some grooves to let the wires pass between the upper and lower part of the base,solder 2 wires ( I used red and green ) one to each of the binding posts, After assembly the two parts are glued ( or screwed might be better ) together.
我（原作者，不是我）用了两小片橡木来做这个小玩意的底座。尺寸不咋重要，请依个人口味定制。两片橡木一上一下，上方的橡木上钻4个孔，两个给接线柱、两个给鳄鱼夹。下方的橡木上打两个孔与上方橡木接线柱背面对应。挖些导线槽以便导线在上下部之间穿梭。焊两根线（我用的红和绿），每根连一个接线柱。组装后把两部分用胶粘起来（用螺丝固定可能更好）。
Step 3: Building the Mini ProtoBoard 第三步：制作迷你面包板
The mini protoboard is simply the plug end from a computer ribbon cable. Pull the top off the cap of the ribbon cable connector. Underneath you will see two rows of pins sticking up. Using fine wire ( I used wire stripped from a Ethernet cable ) connect all the pins on one side together and all the pins on the other side together. Have some of the wire hang out to the side of the connector to connect to the rest of the circuit. { There are a couple of instructables using this technique to make bread boards or protoboards see: Diy breadboard from old IDE cables by 1001progetti https://www.instructables.com/id/Diy-breadboard-from-old-IDE-cables/ and Make your own breadboard by ratgod https://www.instructables.com/id/Make-your-own-breadboard/ }
迷你面包板简单地采用了电脑上的软排线的接插端。把排线接线端上部拔下来，会看到反面有两排突起的针脚。找根导线分别把同一排的针脚连在一起（我用的是剥了皮的网线）。导线要留出点头到接插端外侧以便与其余电路连接。{已经有一些用此法制作面包板的教程，详情可移步：Diy breadboard from old IDE cables by 1001progetti https://www.instructables.com/id/Diy-breadboard-from-old-IDE-cables/ and Make your own breadboard by ratgod https://www.instructables.com/id/Make-your-own-breadboard/ }
Step 4: Add Some Additional Parts & Wire It Up 第4步：添加些附加组件并组装好电路
Solder some wires to the alligator clips ( note in the photos where the wires are connected ). Then hot glue the the clips into the holes in the base. Take the bit of sheet metal and screw it to the base. One of the lugs is under one of these screws. Screw the second lug to the board. Hot glue the mini protoboard board to the base with the wire side down, the hole side up. The black binding post is negative. Using the lug on the sheet metal piece connect on alligator clip and one side of the mini protoboard as negative. The red binding post is positive. Using the second lug connect the other side of the binding post and the other side of the mini protoboard as positive. The binding posts, mini protoboard, and gator clips are all in parallel, the sheet metal is connected to ground. Refer to the pictures.
在鳄鱼夹上焊线（具体位置请看图），然后上热熔胶把鳄鱼夹粘在底座的孔里固定。用两个螺丝将金属片固定在底座上，并在其中一个螺丝下边压一个线鼻子。再用一个螺丝把另一个线鼻子拧在板上。迷你面包板用热熔胶粘在基座上（引线朝下、插孔朝上）。接线柱黑色当负极。金属片上的一个线鼻子与鳄鱼夹相连，同时连接到迷你面包板的一端，最终接到接线柱负极。红色接线柱当正极，并与另一个线鼻子以及迷你面包板另一端相连。接线柱、迷你面包板、鳄鱼夹全部水平向右排列。金属板要接地。具体见图。
Step 5: Use It 第五步：使用
The whole point here is that you can connect the meter to your component with no hands ( of your own ). There are different connectors for different approaches, the pictures illustrate this.
[*]Plug the component into the mini protoboard ( particularly good for components used on protoboards ).
[*]Grab one or more leads with the alligator clip ( particularly good for components with “fat” leads ).
[*]Press a component up against the metal sheet, use you hand for the other end of the component ( particularly good for batteries ). For batteries you can add a dummy load - a resistor in the mini protoboard, 150 ohms is about a 10 ma load for a 1.5 volt battery.
Enjoy.
折腾了半天的全部意义在于: 现在你终于可以实现待测元器件与万用表的无手连接啦:victory:（人手）。图中可以看到，不同的接线方式有不同的接口伺候。
[*]可将元器件插在迷你面包板里（尤其适用于测经常在面包板上安装的那些元器件）
[*]用鳄鱼夹夹住一个或多个引脚（适用于引脚比较胖、肥、粗，彪悍。。。的元器件）
[*]将元器件一端按在金属板上，另一端用手接（尤其适用于电池）。测电池时，还可以根据需要在迷你面包板上接个假负载，如给1.5V的电池接个150欧的电阻产生一个约10ma的电流。
好啦，就到这里，尽情地enjoy吧！:lol

终于有回复了，感谢大神来顶帖 :lol 会翻译本身就多了一臂之力，那小手就不在话下了。 wgsd 发表于 2018-6-2 13:41
会翻译本身就多了一臂之力，那小手就不在话下了。
大神好！可惜目前就只有这一臂，以后要向大神们多学习争取再长半臂:lol rivrz 发表于 2018-6-2 13:51

每次看大神发的东西都感觉好高端，羡慕得不得了，感觉以后能学会的可能性也不大。也许大神自己不觉得。看来真是应了那句话：难者不会、会者不难 创意很好 5448 发表于 2018-6-9 12:23
