电压表ncv是什么意思?

一、电压表ncv是什么意思?

“NCV”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。

万用表上ncv是Non contact voltage 的缩写,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。

用于寻找墙壁里面埋藏带电的电线,(在墙上钉钉子可事先检测一下),或者找寻埋藏的断线线头等。适合较高的交流电压使用,只判断有无电压存在,不能测量具体电压的高低。

二、怎么用万能表NCV测电压?

(一)测量直流电压以Jo411型万用表为例。测量步骤是:1.选择量程。万用表直流电压档标有“V”,有2.5伏、10伏、50伏、250伏和500伏五个量程。根据电路中电源电压大小选择量程。由于电路中电源电压只有3伏,所以选用10伏档。若不清楚电压大小,应先用最高电压档测量,逐渐换用低电压档。2.测量方法。万用表应与被测电路并联。红笔应接被测电路和电源正极相接处,黑笔应接被测电路和电源负极相接处。3.正确读数。仔细观查表盘,直流电压档刻度线是第二条刻度线,用10V档时,可用刻度线下第三行数字直接读出被测电压值。注意读数时,视线应正对指针。步骤(1)按图3-4连接电路。电路不做焊接。可采用图3-5所示方法将导线两端绝缘皮剥去,缠绕在元件接点或引线上。注意相邻接点间引线不可相碰。电路的连接方法(2)检查电路无误后接通电源,旋转电位器发光二极管亮度将发生变化。使发光二极管亮度适中。(3)将万用表按前面讲的使用前应做到的要求准备好,并将选择开关置于Vl0伏档。(4)手持表笔绝缘杆,将正负表笔分别接触电池盒正负两极引出焊片,测量电源电压。正确读出电压数值。记录:电源电压为上 伏。(5)将万用表红黑表笔按图3一4接触发光二极管两引脚,测量发光二极管两极间电压。正确读出电压数值。记录:发光二极管两端电压为 伏。(6)用万用表测量固定电阻器两端电压。首先判断正负表笔应接触的位置,然后测量。记录:固定电阻器两端电压为 伏。在以上三步的测量中,哪一项电压值若小于2.5伏,可将万用表选择开关换为V2.5伏档再测量一次,比较两次测量结果(换量程后应注意刻度线的读数)。(7)测量完毕,断开电路电源。按前面讲的万用表使用后应做到的要求收好万用表

三、ncv万用表能测出多少电压?

ncv万用表能测出交流电的电压,可以测量50V-1000V(50/60Hz)的电压。1. 因为ncv万用表是一种无接触电压测量器,只能用于测量交流电的电压,无法用于测量直流电压。2. 根据ncv万用表官方介绍,它的电压测量范围为50V-1000V(50/60Hz),因此它只能测出在此范围内的电压,而不能测量低于或高于这个范围的电压。3. 另外,虽然ncv万用表可以测量电压,但是它并不能提供精确的电压数值,只能通过灯光或声音等方式提醒用户当前电路中是否存在电压。

四、ncv测量怎么用?

NCV相当于感应电笔,调到NCV档,靠近被测物体,就能够测量出是否有电,不用破皮就知道电线电缆有没有电。

而live其实是火线L线,跟普通电笔是一样的,接触用电一种测量。另外,大多数的万用表都是有NCV功能,用来检测温度一种功能,很适合用在空调维修中。

五、ncv是什么功能?

ncv功能测量是感应电笔。

ncv相当于是感应电笔,可以巡查电线的通断,不用破皮可知电线电缆是否有电。而live就是火线l线,相当于是普通电笔,需要接触用电设备测量。现在很多万用表都带ncv功能,还有检测温度的功能,特别适合空调维修使用。

六、NCV什么意思?

NCV:即“New Concept Vehicle”。它是我国自主品牌奇瑞提出的一个新概念。它是以轿车底盘为平台,兼顾了轿车的舒适性和SUV的越野性。作为新概念“轿车”,它比家用轿车的使用范围更广。2005年3月22日,奇瑞的第五个车系——瑞虎诞生了,这也是奇瑞的第一款SUV,准确的说是“New Concept Vehicle”,也就是新概念轿车的英文缩写。它的诞生也标志着奇瑞转变品牌形象的开始。奇瑞希望瑞虎是以“精品”的身份推向市场的,所以它的上市时间也因此而推迟了近4个月时间,可见奇瑞对它的期望之高。

七、ncv测电笔和ncv万用表的区别?

答:

ncv测电笔和ncv万用表的区别是ncv测电笔能测有无电,而ncv万用表还可测量具体数据。

万用表上ncv是Non contact voltage 的缩写,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。

用于寻找墙壁里面埋藏带电的电线,(在墙上钉钉子可事先检测一下),或者找寻埋藏的断线线头等。适合较高的交流电压使用,只判断有无电压存在,不能测量具体电压的高低。

八、NCV in Education: An Overview of its Meaning and Significance

Understanding NCV in Education

In the field of education, the acronym NCV stands for National Certificate Vocational.

十、ncv测量什么意思?

1、钳形电流表上的“NCV”意思是“非接触电压检测”主要用来判断被测对象是否带电,它的效果就如一根外皮有绝缘层的导线。下面是一款万用表的说明书:

NCV非接触测量电压

(1)量程开关在任何位置均可进行“NCV”检测。

(2)“NCV”含义为“非接触电压检测”无须使用表笔。

(3)按住NCV检测键,仪表液晶屏停止显示,并发出声光提示,表明进入NCV检测状态。

(4)按住NCV检测键,用仪表顶部靠近检测对象,如果存在 30-1000V 交流电压,仪表会发连续声响,同时点亮红色警示灯。

2、如何使用:测量电流时只需要将正在运行的待测导线夹入钳形电流表的钳形铁芯内,然后读取数显屏或指示盘上的读数即可。使用很简单,夹住测量导线就行了。不过现在数字钳形电流表的广泛使用,给钳形表增加了很多万用表的功能,比如电压、温度、电阻等(有时称这类多功能钳形表为钳形万用表),可通过旋钮选择不同功能,使用方法与一般数字万用表相差无几。对于一些特有功能按钮的含义,则应参考对应的说明书。

3、此外使用钳形电流表时应注意以下几个问题:

选择合适的量程挡,不可以用小量程挡测量大电流,如果被测电流较小,可将载流导线多绕几个圈放入钳口进行测量,但是应将读数除以绕线圈数后才是实际的电流值。测量完毕后要将调解开关放在最大量程挡位置(或关闭位置),以便下次安全使用。还有,不要在测量过程中切换量程挡。最后,注意电路上的电压要低于钳形表额定值,不可用钳形电流表去测量高压电路的电流,否则,容易造成事故或引起触电危险。
