The meter loop is hinged and movable in order to open the loop to allow the loop to be placed "around" a single conductor. It is important that the loop be placed around only one conductor as if there is more than one wire conducting, then the fields from multiple wires will interfere with the meters ability to operate.
The meter will have a switch [usually rotary] to change scales, and unless you know the approximate current flowing through the circuit, you should first set the meter to the highest current scale setting, and then switch to lower current scales until the proper one is found.
You have to use an amp clamp on meter rated for dc amps. an ac clamp will not work.
In the past, the 'clamp on' feature of a this type of ammeter simply acted as a current transformer which, in common with all Transformers, would only work with alternating current. Some of these clamp on ammeters have separate inputs which allow them to be used as a regular ammeter as well, and you would need to use these inputs if you wish to measure direct current.
However, there are now clamp on ammeters that are able to measure d.c. current by making practical use of what is termed the 'Hall effect'. When placed within the magnetic field established within the 'clamp' surrounding the current to be measured, a special 'Hall element' produces a small voltage at right angles to a separate current passed through that element by the meter itself. This voltage is then amplified and, since, the voltage is proportional to the field which, in turn, is proportional to the current being measured, the meter can be calibrated in amperes rather than in volts.
The best way to learn to use your digital clamp multimeter is to read the instructions that come with the device when you purchase it. If you have borrowed one from a friend, you may opt to consult YouTube for videos on how to properly and safely use your multimeter.

What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
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.
How can you find motor FLA without the motor nameplate The motor is single phase 120 vac?

What would you use to measure current in a circuit?
There are two ways. With small circuit currents, connect an amp meter in series with the circuit that you want to measure. The meter actually becomes part of the circuit. The second way is with a clamp on amp meter. On AC circuits it acts like a transformer. The magnetic field that is created around a wire, when the current is flowing, cuts the wire coils in the clamp on meter and gives a calibrated readout on an analog or digital readout in the handle of the meter.

What Do Amps Measure?
You can measure the electrical current with an amp meter. Amperage measures the current flow.
What do electricians use to test circuits?
Continuity tester, volt meter, clamp on amp meter, megger and ohm meter.
What is the sign for amp on a volt clamp meter?
A
How do electricians check current flow in a circuit?
For AC circuits, amperage is checked with a clamp on amp meter. There is now in the market place a clamp on amp meter that will work on both AC and DC circuits.
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.
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 easier to measure volts amps or watt?
If you have the right test equipment amps are the easiest to measure. A slip over the wire amp meter is easier to use than a clamp on amp meter. The other two values have to be measured by using test leads from the test equipment.
How do you check ampere draw?
Best way is to use a clamp on amp meter. You need to be able to put the clamp over a single conductor. This is usually easy to do in the electric panel, but for a device you need to split the conductors. You can take an extension cord you don't need and separate the conductors so you can get the clamp on a single conductor.
Can you measure AC current on a power cord?
Not very easily. A clamp on amp meter has to go around only one of the circuit conductors. If the clamp on meter is used around the power cord the two wires in the cord have a cancellation effect and the meter will read zero. If you can separate the load's wires that plug into the cord and clamp around that wire you will get a load amperage reading.
