DIGITAL CLAMP METER

A digital clamp meter is a testing and measuring tool which is used to measure the current flowing through a conductor. Digital clamp meters find application in numerous fields. They can be used to measure current, voltage, continuity, resistance.

How It Work

Clamp meters work on the principle of magnetic induction to make non-contact AC current measurements. Electric current flowing through a wire produces a magnetic field. A current transformer inside the clamp meter senses the magnetic fluctuations and converts the value to an AC current reading.

Steps to Follow While Using a Clamp Meter to Measure Current

• Step 1

Switch ON the meter and remove the probes (if attached)

• Step 2

Select the AC current or DC current function using the dial.

The display should show a jaw sign, which will confirm that the measurement is being detected through the clamp (Read the user manual to see how your meter indicates this)

• Step 3

Open the jaw-like structure using the side lever and insert the conductor through which the current is to be measured

Technicians can do this with their secondary hand so that measurements can be noted down using the primary one

• Step 4

Then close the jaw-like structure and level the conductor between the alignment marks inscribed on the jaws.

If these marks are not shown in your model, try to adjust the conductor in the center of the clamp

• Step 5

The display will show the appropriate reading. Users can change the resolution as per requirements, but most meter models do this automatically.

It is recommended that all measurements should be taken for conductors that are insulated properly.
