Can you measure DC current with a clamp meter? In case you are wondering about this, you have come to the right place for answers. Testing the DC electrical current is a basic measurement, but not many tools can do it right.
Using a power clamp meter with an easy-to-read display and simple settings will assist you better in reading AC/DC current.
Explore this article and understand how to best take advantage of a clamp meter.
Can You Measure DC Current With A Clamp Meter?
AC/DC current implies an electric charge flow and often used to heat generators or motors. When it comes to testing a direct current flow, the best and most basic tool to use is a reliable clamp meter.
But before learning how to measure correctly, you should understand the basics of a DC Hall meter and DC current.
● The Relation Between Clamp Meter and DC Current
The power clamp meter was considered as a single-purpose tester for electricians that begin in the Analog world.
It advances into a digital multimeter (DMM) consisting of various basic functions and improved precision.
In most cases, electricians will use this tool to troubleshoot electrical failures.
A clamp multimeter has an advantage over other devices due to the safety of you not having to break down circuits in the process.
The original clamp meter measurement was meant for large currents like AC via a basic act of transformation.
Later, it has been equipped with the Hall Effect technology specifically to measure DC currents.
As the Hall Effect digital clamp meter is the latest version to measure AC/DC current accurately, it includes some sturdy iron jaws to concentrate the magnetic field that surrounds measured conductors.
Previous models, such as the current transformer clamp, have their copper wires wrapped around the iron core.
This kind of measuring will not be as quick and reliable as the new Hall Effect clamp meter.
In terms of basic electrical knowledge, a current is an electricity flow through a conductor or circuit, measuring in ampere.
This flow can be alternated or directed, so the latter is called Direct Current.
Most household appliances and vehicles run with batteries operating in DC current.
When your battery-powered devices suddenly stop working, you can carry out a test on this current with a clamp meter.
● How Does The Clamp Meter Work?
During the current flowing through a conductor, the current meter measures the generated axial magnetic field without contact.
As the clamp surrounds the wire, it starts a magnetic field via an iron core.
There is an air gap that includes the Hall Effect detector, and the meter detects a magnetic field within this gap to apply a deflection.
A voltage perpendicular will be created by the deflected silicon chip.
In the end, the microprocessor inside the DC Hall meter will convert the voltage to ampere and provides you with the correct current reading.
How To Do DC Current Measurement With A Clamp Meter
Before getting into the process, there are required pre-measurement preparation steps for safety.
They include turning off the meter’s current probes and keep your fingers behind the tactile barrier of its face.
This prevents personal injury or a worse risk of electric shock.
- Turn the dial into its DC function. You will find a jaw display icon indicating that the testing comes from the clamp jaw.
- You want to wait for the clamp multimeter display to stabilize before taking the test. Push the Zero button for improved accuracy. This Zero function only works when the dial is in the right position of DC measurement.
- Press the jaw’s release level, then open it to put a conductor inside for measurement.
- When you close the jaw, adjust the conductor into the center position, following the alignment marks on this jaw.
- Finally, view the DC reading on the power clamp meter display.
So can you measure DC current with a clamp meter with correct results? Of course. A reliable clamp meter will ensure your DC current is always safe without leakage for electrical power safety.
Now you are fully aware of how to measure DC current with a clamp meter, we hope you can quickly apply theory into practice.
