大屏幕有大智慧--FNIRSI-S1大屏数显智能万用表入手体验
日常有接触电子电路纵的人。一般出门都喜欢携带多功能又轻便的万用表,正因如此最近入手了FNIRSI-S1大屏数显智能万用表。

菲尼瑞斯厂家直接在外包装上告诉用户这是一块:大屏数显智能万用表---FNIRSI-S1。

FNIRSI-S1不仅有在国内销售,更是一款外贸销售的热门产品,包装背面拔腿中英双语对产品进行简单的介绍解释。

大屏数显智能万用表果然名不虚传,FNIRSI-S1外形尺寸:143mm*75mm*19mm,目测都能看出屏幕占据了正面一半以上的空间位置,而且字体也是大号加粗显示。不管是读数还是在给人的感觉感觉都是相当强烈。
![](https://p0.ssl.img.360kuai.com/t01a0a32fef84e576d8.jpg)
FNIRSI-S1在背面设计有一个照明用的LED灯,还能在背后的丝印标记中发现内置电池的容量是1000毫安。并且通过扫描二维码还可以关注官网上的最新信息。

FNIRSI-S1大屏幕智能万用表抛弃了传统式的转盘式的设计,直接改为全按键式操作,开机键位于万用表的顶部,按下就可以开机。USB TYPE-C 充电接口设计在同侧旁边。
![](https://p0.ssl.img.360kuai.com/t01b2b23f5943881b0b.jpg)
万用表的侧框设计有防滑凹槽,手持时握持更加的稳当。
![](https://p0.ssl.img.360kuai.com/t01c932318d7e39141f.jpg)
表笔的孔位设计在底部。左边为COM公共端接黑色表笔,右边为输入端接红色表笔。
![](https://p0.ssl.img.360kuai.com/t01cf47eb607e130912.jpg)
将近3.5英寸的屏幕配合上粗大的字体,给人印象相当的深刻,并且开机默认在AUTO档上,即使忙乱之下直接入带电目标检测也不会损坏的顾虑。
![](https://p0.ssl.img.360kuai.com/t016ad80ca04f2f25d5.jpg)
万用表正面可以算得上相当简洁,主要也只有三个按键。主要选择功能就是中间的SEL功能按键。
![](https://p0.ssl.img.360kuai.com/t01750d1c995c0a6939.jpg)
FNIRSI-S1自带有一对特尖表笔,这对于测量电子电路的细细的引脚可以说是一大福音。
表笔的孔位设计在底部。左边为COM公共端接黑色表笔,右边为输入端接红色表笔。

一台万用表除了智能及便捷的操作性,轻巧的机身也是一个相当不错的亮点。裸机的重要也才142克,比自己天天带身上的手机还轻了一点,外出做事情不带才怪。
![](https://p0.ssl.img.360kuai.com/t01e9c671ecc52f77ea.jpg)
做为一款万用表,开机之后就默认在自动档的位置,这时用户就可以直接测量通断与电阻等操作。为了照顾到一些习惯于传统数字万用表的用户及一些专门的档位,通过按动万用表上面的“SEL”选择键就可以对相应功能进行选择:直流电压、交流电压、通断(蜂鸣)、二极管、电容、频率、温度。
![](https://p0.ssl.img.360kuai.com/t013b0174e2bf7f80e6.jpg)
先来试一下我们日常出门进行家居电力维修常用的交流电压测量:233V,在这个档位还能看到交流电的频率:50.03HZ。FNIRSI-S1测量端和大地之间允许的最大电压: 1000V直流或1000V交流有效值。Hz是赫兹的缩写,代表一秒钟电流周期性变换方向的次数,50Hz表示1秒钟电流有50个周期,方向改变100次。此款智能万用表最大可以测量1000kH的频率。
![](https://p0.ssl.img.360kuai.com/t01228ba94b96208791.jpg)
默认开机FNIRSI-S1默认的就是AUTO档开局。
![](https://p0.ssl.img.360kuai.com/t01e20313a88508f743.jpg)
电阻档量程范围:0-100MΩ,测量一下100Ω的电阻,这精度还是令人满意的。
![](https://p0.ssl.img.360kuai.com/t016b9cc46d8d1b9af9.jpg)
测量标称10微法的电容,测量值为:8.3微法,此电容容值正常,可以使用。FNIRSI-S1电容量程:0-10mF。我们日常所遇到的电容都能测个遍了。
![](https://p0.ssl.img.360kuai.com/t0190ac7d04df08eda5.jpg)
在电路测量中必不可少的二极管档,这个就不用多说了,懂的都懂。
![](https://p0.ssl.img.360kuai.com/t01fde4c96503bcea04.jpg)
![](https://p0.ssl.img.360kuai.com/t0187d9e6561e610a8c.jpg)
对于一些电子元件的检测通过这种夹式表笔体验还是相当不错的。
![](https://p0.ssl.img.360kuai.com/t01c09e043f9498727e.jpg)
这两天晚上气温有些低,再加上开个空调室内温度还是有点低哦。
![](https://p0.ssl.img.360kuai.com/t01de50811f3a6ffc0a.jpg)
按“NCV”键,可进行NCV测量; 再按“LIVE ”键,即进入火线(LIVE)测量。(其实这两个键是一键双用)
![](https://p0.ssl.img.360kuai.com/t015d9273307cc43a3b.jpg)
做为一款智能万用表,现在主流的NCV功能肯定是必不可少的。所谓:NCV是non contact voltag的缩写,含义为“非接触电压检测”,用来判断被测对象是否带电,如一根外皮有绝缘层的导线。就是采用电磁或电场感应的原理判断是否有电压的存在,类似于感应测电笔功能,不用并测试表笔直接接触带电物。
![](https://p0.ssl.img.360kuai.com/t01f5e91ada8bf4077b.jpg)
NCV功能相当好用,毕竟在对未知线路操作以前没有检测是否带电,都要默认带电,经过正常检测之后确定是否带电后再安排如操作,保持良好的安全习惯是做好事情的第一要绝。
![](https://p0.ssl.img.360kuai.com/t01e3479ddc05068ce4.jpg)
常见的万用表一般都带有屏幕背光功能,这个当然对于FNIRSI-S1来不算什么,更先进的是这块万用表竟然在背后还带有灯光照明功能,要是遇到被检测目标处在光线不佳的环境下就可以按下HOLD-灯光 键就可以直接打开。
![](https://p0.ssl.img.360kuai.com/t0172e3324369714407.jpg)
要是晚上临时走路需要照明的话,光线也是足以应付的。
![](https://p0.ssl.img.360kuai.com/t01c13226190023e7f1.jpg)
通过USB TYPE-C充电接口就可以对万用表的内置充电电池进行充电操作。FNIRSI-S1 的5V 1A充电电压让市售的充电器都能很好的兼容应用。之前在官店同时入手的高颜值的充电头和TYPE-C充电线直接可以应用。
![](https://p0.ssl.img.360kuai.com/t0176c10f0b569d1378.jpg)
充电时S1型号标记处充电指示灯会呈现红灯充电,等到充满时绿灯亮起时就说明充满了。
![](https://p0.ssl.img.360kuai.com/t01e73d14cf1b206681.jpg)
这块万用表工作环境在海拔高度<2000 m,工作环境温湿度:0-40 (<80% RH,<10时不考虑),储存环境温湿度:-10-60 (<70% RH,取掉电池),温度系数:0.1准确度/ (<18或>28 )。日常随身携带外出或者保存起来最好能用个包装进行相应的保护。
FNIRSI-S1入手体验:
做为一款智能多功能万用表,FNIRSI-S1屏幕够大,字体够粗的给个人留下了深刻的印象,机身后背后的照明灯设计是很多常见的万用表所不具备的,要是遇到一些光线不佳的场景就可以派上用场。自带的NCV功能在非接触条件能也能协助操作人员测量线路带电情况。一档多能的方便技能更是让人爱不释手。
如果标配的万用表笔是平插式的表笔,放置在桌面上时感觉会更好。
