Ho w Do You Measure Electricity With A Clamp Meter?
A clamp meter is an electrical tester that measures the flow of current in a circuit and the appropriate voltage in it. The device is based on a regular multimeter, with the only difference that the user can measure the current without coming in contact with the wire. As the name suggests, a digital clamp meter consists of a jaw-like structure at the mouth which allows you to put the structure around the wire and take the reading. The structure comes with a high-fidelity sensor which detects the current flowing through the circuit. You can get a digital clamp meter online if you want one. The clamp meter price is reasonable if you buy it from the online vendors. Components of a digital clamp meter Before you get into work with a digital clamp meter, it is imperative to know the parts in detail. Here is a lowdown of the components of a clamp meter. 1. Clamp: It is the jaw-like structure which is used to detect and measure the current by putting it around the circuit. 2. Tactile Barrier: It protects your body from shocks. 3. Hold: The hold button stops the reading until the button is pressed again. 4. Display screen: Mostly LCD. 5. Min-max button: This button is used to measure the highest, average and the lowest quantities. 6. Shift Button: To choose extra functions on the dial. 7. Alignment marks: It helps the user to align the jaw-like structure at a position where the reading can be taken accurately. How do digital clamp meter measure current? The principle on which clamp meters work is similar to that of a transformer. The jaw-like structure of the clamp meter has ferrite in its core with copper windings around it. When the structure is put around the current-carrying wire, it detects the current and couples it. The coupled current is then sent from the ferrite core to the shunt of the device. The current that is coupled is of a very small amount. So, the device comes to a correct value by multiplying. It then displays the right current magnitude.
