A clamp-on meter works by measuring the magnetic field set up around a conductor. Because the currents in the line and neutral conductors flow in opposite directions, their fields cancel and the clamp-on meter has nothing to monitor. So it must be placed around either the line OR the neutral conductor -not both!
What else can I help you with?
How do you identify nutral and earthing wire if they change?
Making a load On, By using a clamp meter for measuring the current in the wires : we find a reading in Amps. if we clamp the neutral wire. and zero when clamping the earthing wire.
What do you use a clamp meter for?
The clamp part is for measuring amps via induction. You set meter to amps and clamp around only a single wire. Device you are measuring must be operating. This means you couldn't clamp around a lamp cord to a table lamp since the current induced in each direction cancels out. You would have to separate the wires. An electrician would carry a short extension cord with the wires already separated. Most often a clamp meter is use to checks amps in a breaker panel on the black wire coming from the breaker.
What are the basic test instruments in electricity?
A "multimeter" to test resistances, voltages, amperages. An external "clamp" meter to measure high ac currents. A "mega" meter to test insulation.
Can you measure amp in the DC?
Yes but the meter has to go in series with the load. There is a new clamp on amp meter being introduced, that will measure larger DC amperages without opening the circuit.
What is a tong amp meter?
A type of current transformer used as a metering device. You clamp the tong around a wire and it will tell you how many amps are flowing though it.
Explain basic principle of analog clamp meter?

How can measure nutral and earthing wire?
Nutral wire can be measured by using clamp meter, if there is a current passing through the wire, we got a reading in the clamp meter i.e. 2A. If we clamp the earth wire by the clamp meter the reading will be zero.
What is the Working principle of taung tester clamp meter?
CLAMP METER WORKS WITH THE PRINCIPLE OF HALL EFFECT..
How do you identify nutral and earthing wire if they change?
Making a load On, By using a clamp meter for measuring the current in the wires : we find a reading in Amps. if we clamp the neutral wire. and zero when clamping the earthing wire.
How-to use the clamp-on meter Model GCM-600?
how to use the Clamp-On Meter Model GCM-600 to find the current of a DC power?
What is the sign for amp on a volt clamp meter?
A
How does a DC clamp meter work?
A DC clamp meter works by measuring the magnetic field produced by the flow of direct current in a conductor. When the clamp is placed around the conductor, it detects the magnetic field and converts it into a direct current measurement. This measurement is then displayed on the meter's screen.
How an amperage reading would be taken using a clamp-on?
Simply "clamp-on" the clamp of the amp meter to any electrical conductor supplying the equipment that you wish to check while it is in operation. It is better to use your clamp-on with each individual conductor one at a time.
How do you measure amps on a 208V single phase circuit with a clamp on amp meter?
Clamp the meter around the energized conductor that is connected to the load to be measured and read the amperage off of the dial face of the meter.
Where can one buy a used clamp meter?
One can buy a used clamp meter at pawn shops and stores that sell home improvement supplies that are left over from construction jobs. There are several online sites that also sell used clamp meters.
What would someone use a fluke clamp meter for?
A fluke clamp meter is used for electrical purpose by electricians. You can use them to measure things such as a large air condition currents. Different clamp meters have different features such as being able to measure motor inrush currents.
What would one use a clamp on meter for?
A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of the currents. Only one conductor is normally passed through the probe. In particular if the clamp is closed around a two-conductor cable carrying power to equipment, the same current flows down one conductor and up the other; the meter correctly reads a net current of zero.
