Digital Clamp Meter, Purpose and Where to Get

The need to measure the electricity is not unique to the corresponding profile of employees, but also ordinary people. In this case, become irreplaceable tongs electric differing usability. This tool allows to performing practically all measurements of electrical parameters, such as voltage or current. When this is not changed during network operation, it is no gap. Devices classified into several types depending on the measured value: wattmeter; ammeter; phase meter; ohmmeter.

The most popular clamp meter (e.g. digital clamp meter DT266) is necessary for determining the AC current in the conductor. They take into account the physical processes of the current transformer, which has two windings. The first bus is the measured parameters, and the second compound has a special magnetic circuit.

Primarily they are used to calculate the network load. The single-phase version of the work carried out in the following sequence: on the incoming conductor measurements are carried out, the parameters obtained are multiplied by the supply voltage and the cosine of a phase angle (in the absence of reactive load it is equal to unity). Also with the help of this tool, you can determine the power or electrical household appliance. It calculates the result by the formula, which should take into account the current value at a certain part of the chain. In addition, the clamp meter is suitable for testing instruments in particular ascertain their correct operation. So you can find out if there are any discrepancies in meter readings and actual energy consumption.

To begin to open the tool and take them to a single cable, which may be of any phase. After closing the screen displays the parameters defined value. If you want to take measurements in a place with complicated access, you can use the special button, designed to secure the evidence. That is, the value will be displayed on the screen even when disconnected from the conductor. It use possible on installations of any kind, both closed and open. Measurements in the open air should be carried out only when suitable weather conditions and lack of rainfall. BTW, you can select the clamp meter at Banggood. Besides, you can easily get other electrical accessories (e.g. air rotary tool) there with high quality and reasonable prices.
