A digital clamp meter is a portable meter that can measure the AC current of a circuit by continuously disconnecting the circuit. Because of the easy use and portability of the digital clamp meter, it is widely used in the overhaul and overhaul of some circuits. The working part of the digital clamp meter is mainly composed of an electromagnetic ammeter and a feed-through current. Next, let's take a look at what a digital clamp meter is and some of its usage and reading methods.
What is a digital clamp meter?
A digital clamp meter is also called a clamp meter, which is an instrument that can clamp a wire and perform current detection without cutting the wire. The digital clamp meter can measure the current of the wire only by clamping the sheath of the wire, which makes the operation easier and safer.
How to use digital clamp meter and matters needing attention
How to use the digital clamp meter:
1. Before measuring, perform mechanical zero adjustment;
2. Next, you need to select the appropriate range, according to the principle of selecting a large range first and then a small range, or you can estimate it according to the nameplate value of the electrical appliance;
3. When using the minimum range for measurement, the reading may not be obvious. At this time, the wire to be measured needs to be wound a few turns, and the number of turns should be based on the number of turns in the center of the jaw. In this case The reading is: reading = indicated value × range / full deviation × number of turns;
4. When measuring, the wire to be measured should be located in the center of the jaws, and the jaws should be closed tightly, which can effectively reduce errors;
5. When the measurement is completed, switch the replacement switch to the maximum range.
Precautions for the use of digital clamp meters:
1. The voltage of the line to be measured must be the rated voltage of the lion clamp meter;
2. When measuring the current of high-voltage lines, be sure to wear insulating gloves, insulating shoes and stand on insulating pads to ensure safety;
3. The jaws of the digital clamp meter must be closed tightly, and measurement cannot be performed under the condition of electrification.
Digital Clamp Meter Readings
The clamp meter is divided into two types: needle type and digital type. Compared with the needle type clamp meter, the reading method of the digital clamp meter is extremely simple. You only need to use the correct measurement method to measure and wait for the digital display. After the number is stable, you can read it.
The digital clamp meter can be widely used in some industrial production and some life. It can not only be used for the overhaul of some circuits, but also for the overhaul of some electrical appliances. It is a common tool. Compared with some ordinary current test meters, digital clamp meters not only have the characteristics of convenient use and simple operation, but also have the characteristics of safety, speed and portability. This instrument is often used in daily life, and its easy-to-carry feature brings great convenience to our lives. Knowing how to use some digital clamp meters and some reading methods can help you use it better.
