1888金博宝

The Introduction

这简直是​​不可能的,而无需使用万用表做任何电气工作。但是,在我们向前走,让我来解释一下这件装备真的是。

A multimeter aka multitester, also known as VOM, is an electronic measuring instrument. It can measure voltage, current, and resistance between two points in an electrical circuit.

Are there different kinds of multitester?

As a matter of fact, there are two types of VOM. There is an analog VOM that uses a microammeter with a moving pointer to display readings. And, there is the digital VOM that is superior to the analog multimeter because of its accuracy in readings.

Another advantage of digital VOMs is that it is very sensitive to minute changes in input voltages. Also, it has a clear and easy-to-read display.

Now, it even has computer connectivity, speaking measured value, thermocouple probe for temperature measurement. So, the job of the electrician has become so much easier.

但是,为什么如此重要的是使用万用表?

正如前面提到的,VOM的是任何种类的电气工作至关重要。通俗地说,你必须检查所有电气连接的两端使用任何电器之前检查电流和电压。

例如,你在固定吊扇。你必须检查电压,电流,并在该点的布线电阻在风扇要连接以及在风扇开关将是交换机。

And, if you haven’t done that then you’ll have either burnt sockets, burned electrical wiring, ruined electrical appliances, and in the worst-case scenario, a fire in your home.

你看,在电压的差,在电流的电阻会导致在你家中的电力线路严重损坏。

那么,什么是你可以面对用万用表的危害?

首先,你可以从电击或电弧闪光事件受到影响。这些可通过电压瞬变或尖峰电压所引起的。它甚至可以从电击受苦,如果你的设备损坏或对VOM探头不绝缘。

There are many reasons that may cause shock or arc flash, but there are certain precautions that can be taken to minimize the risk.

你应该怎么做,以尽量减少风险使用VOM什么时候?

要做的第一件事就是打电话给一个专业做房子周围的任何电气工作。有时,聪明的做法是花了一些,并得到帮助,而不是让自己触电。

接着,一对橡胶绝缘手套的应始终可以得心应手。甚至,如果是电工,你叫了过来。

Make sure that the multimeter is not faulty or has any damaged parts. The VOM you use must have insulated probes.

And, if you feel this is something you can do, then please get some training in the field before you do try your hand at it. This can easily be achieved through a local vocational training center. And, if you need a VOM, you’ll a good one even不到$ 100.

The Conclusion

Our advice is to learn to use a VOM and before you try sticking it into an electrical socket. And, if you don’t have the time for this, then call an electrician. Rememberelectrical safety precautionsare a must.

Electrical work should be carried out very carefully especially in rooms with high humidity. I recently finished renovating the house We had some difficulties with the renovation of the bathroom. The room is not standard in shape, high humidity . This all needs to be taken into account.

您还需要考虑在浴室电网能够连接的家具。我花了24英寸浴室柜https://newbathroomstyle.com/product-category/24-inch-bathroom-vanities/
It needed a power grid to connect the lighting. But my bathroom is amazing now.
