Know More About Triplett Clamp Meter

What is Clamp Meter?

A clamp meter is a safe, convenient, and efficient way to measure current without having to use test leads. Since current flow through a conductor causes a magnetic field, the ac dc clamp meter can sense this field and provide a corresponding current reading (in amperes, or amps). Digital Clamp meters do not interrupt current flow allowing the technician to make the measurement quickly and safely. These meters are used for various applications such as testing for electrical shorts, identifying over-currents, and measuring DC voltage. The popularity of our AC/DC clamp meters can be attributed to several factors. First, they are easy to use and can be operated with one hand. Second, they are compact and portable, making them ideal for use in tight spaces. Finally, clamp meters are versatile and can be used to measure various electrical parameters.

Why True RMS Clamp-Ons?

A True RMS clamp meter more accurately measures AC (alternating current) signals. When measuring distorted or non-periodic AC waveforms, True RMS clamp meters are essential. Standard meters, without True RMS, average the AC measurements and therefore are not as accurate for AC. True RMS (Root Mean Square) clamp meters are one of the most essential tools that engineers and technicians use in their work. These digital multimeters are especially important because they give you accurate readings even when the voltage is not constant. This is essential for troubleshooting electrical problems. True-RMS digital multimeters are different from other digital multimeters in that they use a specialized algorithm to calculate the RMS value of an AC signal. This allows them to provide accurate readings even when the waveform of the signal is not a perfect sine wave. If you need to measure AC signals, then a true-RMS digital multimeter is the best tool for the job. Although, true RMS clamp meters are more expensive than other types of digital multimeters, their accuracy and versatility make them worth the investment.

  • Electrical Troubleshooting: When diagnosing electrical issues, True RMS clamp meters can provide accurate measurements even in scenarios where distorted waveforms are present due to electronic devices, dimmers, or other non-linear loads.
  • Motor Testing: True RMS clamp meters are used to measure the inrush current when motors start up, as well as to monitor the running current of motors during operation.
  • Renewable Energy Systems: In applications like solar panel installations and wind turbine systems, True RMS clamp meters help monitor AC current and voltage accurately, ensuring proper system performance.
  • Data Centers and IT Equipment: True RMS clamp meters are used to measure current and voltage in data center equipment and IT racks to ensure proper functioning and power management.
  • Electrical Safety Inspections: For compliance with safety regulations, True RMS clamp meters are employed to assess ground fault circuit interrupter (GFCI) and residual current device (RCD) performance accurately.

What are the Types of Clamp Meters Offered at Triplett?

At Triplett, we provide various types of clamp meters to suit your needs.

  • AC/DC Clamp Meter: Our Triplett Model CM450 True RMS clamp meter is the most popular AC/DC clamp meter on this list. It can measure DC and AC current up to 400A without damaging the circuit. It can be easily clamped around a single conductor.
  • Mini Clamp Meters: These are compact sized clamp meters designed to be operate in small spaces. They can capture the instant surges when the current is turned on.

What is the Measurement Principle of AC/DC Clamp Meter?

Our AC/DC clamp meter works by clamping around a conductor, such as a wire, and then measuring the current flowing through the conductor. The working principle of the meter is relatively simple. When the jaws of the clamp meter are closed around a conductor, a magnetic field is generated. This magnetic field is used to measure the current flowing through the conductor. The strength of the magnetic field is proportional to the amount of current flowing through the conductor.

What are the Main Parts of the Clamp Meter?

There are three main parts to a clamp meter: the body, the jaws, and the display. The body of the clamp meter houses the electronics and the batteries. The jaws of the clamp meter are used to clamp around the conductor, and the display shows the current measurements. The other major parts of the unit are:

  • Power Switch
  • Back Light Button
  • Hold Button
  • Positive and Negative Terminals
  • Hold Key
  • Functional Rotary Switch

How to Use a Clamp Meter?

Here are the steps you need to take in order to use a clamp meter.

Select the right clamp meter for the job. There are several different types of clamp meters, so make sure you select the one that is best suited for the task at hand. Connect the jaws of the clamp meter around the conductor you want to measure. Make sure that the jaws are completely closed in order to get an accurate reading. This helps improve the gripping of the device. Take the measurement. The reading on the clamp meter will indicate the amount of current flowing through the conductor. Repeat the process as needed. You may need to take multiple measurements to get an accurate reading. When you're finished, remove the clamp meter from the conductor and turn it off.

What is a Hall Effect Clamp Meter?

Hall effect clamp meters can measure alternating as well as direct currents up to a range of 1000Hz. After every reading, these clamp meters need to be adjusted to zero to eliminate offsets. Unlike most clamp meters that have copper wires, hall effect clamp meters have iron jaws for that surround the conductor where the magnetic field is produced. The point at which the jaw tips meet has gaps that form an air pocket. The magnetic field skips the air pocket so that the magnetic core does not saturate. This is because the air gap is small and hence the magnetic field is concentrated in that small portion. There is a Hall effect transducer of sensor in these gaps, which is covered in a thin plastic enclosure. This sensor responds to the magnetic field in question by variation in the output voltage, which is directly proportional to the magnetic flux. This way it directly measures magnetic flux. The core that the iron jaws form allows the magnetic field to pass through it. The clamp reads this voltage and converts it into current reading that is displayed on the screen. Triplett offers a variety of Hall effect clamp meters with multiple features.

What is a Current Transformer Clamp Meter?

This clamp meter works like a transformer that has ferrite iron jaws covered by copper wired coils. These jaws form the magnetic core when measuring current. Most times, the conductor acts as the primary winding for these transformer clamp meters, while the coils act as the secondary winding. An alternating magnetic field is produced by the current flowing through the conductor. On the other hand, the iron cores of the clamp generate current flow in the secondary coil. The amount of magnetic field around the conductor is called magnetic flux. If the secondary coil has “n” number of windings, then the ratio of the secondary current to that in the primary coil would be 1/n. This way any amount of current can be measured by increasing the windings in secondary coil. Most models of the clamp meters we offer provide the measured current in mV.

Current Electrical Clamp Multimeter with DMM functionality

Triplett leads the market in multifunction current clamp meters. In the presence of high current flow, the need to measure volts, ohms, temperature, and frequency is imperative. Multifunction current clamp meters offer a value-added bonus for technicians, field engineers, and contractors.

What is the significance of the IR thermometer?

In areas where there are high current carrying conductors, safety is of utmost concern. With an IR thermometer built right into the clamp meter the technician can quickly and safely scan for ‘hotspots’ on panels, conduits, and walls.

We have an efficient team who can assist you in finding the correct DC and amp meter clamp that suits your application requirements.
