What Are Clamp Meters Used For?

How Helpful Are Clamp Meters In Murrieta Homes?

Clamp meters is an electrical meter with integral AC current clamp. Another main aspect of clamp meters is the ability to attach the instrument to the line being tested without the need to disconnect the cable first. The large, illuminated, dual display on the clamp meters is easy to see in poorly-lit job sites and features a 4-digit (6,000 counts) readout complemented by a bar graph display.

Calibration of clamp meters is a mainstay of many electrical calibration laboratories, but understanding the errors associated with the calibration of clamp meters can be daunting. Clamp meters is designed for electrical inspections, making it easier to take measurements around multiple conductors, crowded panels, tight switch gears, large bus bars and wire bundles. Today’s clamp meters are capable of measuring both AC and dc voltage.Clamp meters are often used with what is essentially a short extension cord with the two conductors separated so that the clamp can be placed around only one conductor of this extension.

About Clamp Meters

Clamp meters are electrical testers featuring wide jaws that are able to clamp around an electrical conductor. Originally designed as a single-purpose tool for measuring AC current, clamp meters now include inputs for accepting test leads and other probes that support a wide range of electrical measurements. Indispensable as a test tool, the jaws of a clamp meter facilitate work in tight spaces and permits current measurements on live conductors without circuit interruption. Though clamp meters are closely related to multimeters, they are not simply multimeters with inductive jaws replacing test leads. Generally, multimeters can be seen as voltage-measuring instruments with some current-measuring ability while clamp meters are current-measuring instruments with some voltage-measuring ability.

Clamp Meter Technology
Clamp meters rely on the principle of magnetic induction to make non-contact AC current measurements. Electric current flowing through a wire produces a magnetic field. Since alternating current frequently reverses polarity, it causes dynamic fluctuations in the magnetic field which are proportional to the current flow. A current transformer inside the clamp meter senses the magnetic fluctuations and converts the value to an AC current reading. This type of measurement is convenient for measuring very high AC currents.

Direct current, however, flows through conductors in a fixed polarity. Consequently, the magnetic field around the conductor does not change and conventional clamp meters will register no reading. DC clamp meters work on the principle of the Hall Effect. Hall effect sensors sense the magnetic field caused by current flow which causes a small voltage across the Hall effect sensor. That voltage, which is proportional to current is then amplified and measured. Read more here.

Clamp meters are used by electricians, sometimes with the clamp incorporated into a general purpose multimeter and preferred for measuring high levels of current.

How to Use a Clamp Meter

This allows one to measure the current on a wire without interrupting the operation of the electrical appliance. A clamp meter uses digital technology to bring instantaneous readings. Here is simple guide to operating a clamp meter.

Step 1. Buy a Clamp Meter
Go to the electrical supply shop and purchase a clamp meter. Some clamp meters also provide features that can measure voltage, while some clamp meters only measure current.

Step 2. Choose an Electrical Conductor to Test
The clamp can easily measure the current on a load without the need to disconnect the electrical conductor from the circuit. To get a reading, the electrical wire should be connected to an electrical appliance that is running or operating. As a safety precaution, it is best to remove the wire from the power source first before getting a reading.

Step 3. Choose the Appropriate Function and Range
Set the rotary selector on the clamp meter to the correct function and range. Measuring current that is higher than that specified in the range can damage the device. In addition, the electrical conductor should be running on voltage lower than 600V. The device cannot read the current on conductors running on very high voltage. If not sure about the range, choose a high range and decrease it as needed. See more here.

Clamp meters are designed to detect the dynamically changing magnetic field produced when electricity flows through a wire.

Advantages of Using a Clamp Meter

When you think about today’s world, you can not imagine it without electricity. After all, what would you do if you were not able to use all of your gadgets or home appliances? What would you do if you did not have electric light? Can you imagine living in a world where electricity is not the main thing that keeps us powered? The answer is definitely no. The most important thing that you need to understand about electricity is the fact that it fluctuates and depending on its intensity and other factors, it might keep certain devices working properly or it might damage them. When it comes to plants and all sorts of machines used there, an Energy Management tool such as a Clamp Meter is more than necessary.

One of the advantages of owning a Clamp Meter is the fact that you are able to measure the electric current that passes through a device without the need of breaking any circuits. Why is it important to make sure that the electric current is in the right range? Well, when you have a plant that is filled with all sorts of machines working to produce certain elements, you count on electricity and on them working properly. Now, if there is a fluctuation in electric current and the intensity is too much for one of the machines to stand it, it will get damaged, fact that will lead to stopping production. When you are producing certain items in a plant, you have a deadline.

Moreover, you have to make sure that you do not keep the plant on standby at all because time does mean money in this case. There are all sorts of Energy Management solutions that you could use in order to make sure that everything is working properly, but one of the most important ones is a Clamp Meter. You need to be able to have accurate readings of the electrical current passing through the machines regularly. This is the only way that you could know for sure that everything is working as it should. There might be all sorts of circuits and faulty cables that might lead to serious damage of a machine or more. Read full article here.

Clamp Meters Will Save You Time And Money!

Clamp meters are ammeters that can measure current without the need to disconnect the wires where the measurement occurs. Clamp meters are a special designed Meter used in electrical maintenance operations. Most clamp meters can accurately measure AC voltages with frequencies from 50 Hz to 500 Hz, but a digital multimeter’s a measurement bandwidth may be 100 kHz or higher.

Most clamp meters can get more than 150 hours of operating time out of two standard AA batteries. Not all clamp meters are created equal and it is important to purchase a quality clamp meter that will provide accurate results in the types of environments where you will be working. Different types of clamp meters can measure different ranges of AC current, DC current, and AC current frequency, for more information you may reach us here: (951) 805-1262.
