You would use a clamp on amp meter for measuring the electrical current of an outlet or wire. The clamp allows the meter to get an accurate reading without the user having to worry about the meter moving around too much.
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.
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.
To get a water meter installed you generally have to have someone install it for you, and you can either apply to have someone do that for you, or pay a professional to do it.
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.
Current is measured in amps so the setting on a multimeter would be A Measuring current with a multimeter is only to be done by someone with training because it can be very dangerous It is much better to measure current with a clamp meter
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.
'Fluke' is the term for the lobe of a whale's tale, usually used as a plural. One would say, "look at the whale's flukes."
The only way is to use a meter, it does not have to be expensive. Radio Shack offers inexpensive meters. Simply "clamp" the meter around the circuit you want to test. Good Luck.
Usually nothing. (You would not get a reading either) The other way around (connected to measure current but set on voltage reading) will burn a fuse or the device entirely. On my Fluke 23 it will blow the fuse.
If the two wires are on a parallel feed you would read the current through the parallel feeders. If the two wires are "hot " to the load and return back from the load the meter will read zero. The two magnetic fields that surround the wires when a current flows through them will cancel each other. As a result of this there will be no magnetic induction induced into the sensing coil of the clamp on meter.
