Go to radio shack. Ask for "Alligator clips". Buy a few that the tip of your ammeter probe fits snugly into the wire loop. You now have an ammeter probe with a clip on the end. Cost: ~$1
Alternatively, they sell pre-manufactured clip leads for most ammeters, which consist of a plug-in jack to the meter, a wire and an alligator clip at the other end. They're around $20.
If you mean a "clamp-on" ammeter that detects current by proximity to a hot wire, I don't know how to make one, other than the fact that they work on the principle of induction coils. Probably a multi-meter and a coil of wire would suffice to *detect* current. You'd have to calibrate readings for your specific coil with known currents to use it for a reading other than hot/not-hot. BUT: At around $30 for a cheapo clamp-on meter, you're undoubtedly better off buying one, or just learning to use a multi-meter and probing the wire. Homemade electronic devices are fun until your DIY project gets you killed trying to prox text 440V 3-phase with your jury-rigged science project...

Which of these is used to measure current in series circuits?
Ammeter
What are the functions of an ammeter?
An ammeter measures the amount of electrical current flowing through a conductor.
How do you connect an ammeter and voltmeter?
The voltmeter is connected across the supply and the ammeter is connected in series with the supply.
Why is ammeter connected in series with the load?
A ammeter will tell you how much current draw the load is drawing
What is the importance of an ammeter?
ammeter is a measurement tool used to calculate the current flow in electric and electronic circuits
A clamp-on ammeter measures what?
Current flow
What does a Clamp-on ammeter measure?
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
What is a 10 wrap amperage multiplier used with?
clamp-on ammeter
How can you test the mAh output of a power source?
You measure it with a clamp-on ammeter.
When measuring with an ammeter the ammeter must be connected in?
When measuring a load current, an ammeter is connected in series with the load. The exception is for a clamp on style AC ammeter, which is clamped around one of the conductors, making its measurements as a transformer.
Does a clamp-on ammeter measures voltage?
No, it will only measure the current through a single phase.
HOW Does a clamp-on ammeter measures current by capacitance?
A clamp-on ammeter does not measure current by capacitance. It forms a current transformer that operates by inductance. The clamp-on part is the magnetic core of the transformer. There is another winding inside that is coupled by the core to the line that is being measured. This second winding is shorted and the device reads the current through that winding. The current is proportional to turns ratio.
What type of accessory device can be used to measure AC with a VOM without opening the circuit?
Electricians use a clamp or clamp-on ammeter to measure current. The handles are squeezed together and the "jaws" open up. The clamp is then slipped over the conductor and the handles are released. The "jaws" close around the conductor and the meter is then in a position to measure current in that conductor. When current flows in a conductor, the current generates a magnetic field around the conductor. And the clamp-on ammeter can "feel" the current and measure it, thus permitting an investigator to know how much current is flowing in that conductor. The clamp-on ammeter is a stand-alone meter, but can sometimes be the kind that is plugged into a digital multimeter (DMM). A link to the Wikipedia article on the clamp ammeter is provided.
A clamp on ammeter measures?
Measures current by magnetic field induced into the clamp. You need to clamp a single conductor. For example you couldn't just clamp a lamp cord since it has two conductors and the current is going in opposite directions and the fields cancel each other out.
What does a Clamp-on ammeter do?
It is an electrical device with two jaws that open to allow clamping around an electric conductor. This allows the current in the conductor to be measured.
Can you use ac ammeter to measure dc current?
It depends. If it's an inductive ammeter (the kind that clamps around a wire), it won't work at all. If it is the type of ammeter that is actually placed in the circuit, it will work but it won't be accurate.CommentActually, modern 'clamp on' ammeters WILL measure d.c. currents. It uses the Hall Effect to measure the current.
Can DC ampere be measured with AC amp meter?
No. The ammeter must be designed to measure DC. Some clamp-on ammeters are designed to measure both AC and DC.
