very CAREFULLY You must start at the high level and step down. otherwise permanent damages to the meter will be evident.

What does MA mean on a multimeter?
MA or mA on a multimeter designates milliamps, or "thousandths" of an amp of current flow.
What instrument measures voltage?
Resistance is measured with an ohmmeter. A link is provided to a brief article on the ohmmeter posted at Wikipedia.Note that it is unusual in this day and age to have a device that will measure ohms and nothing else. The ohmmeter is usually included among the functions of a multimeter, and usually a digital multimeter or DMM.
Who invented the multitester?
Donald Macadie, post-office engineer, invented the first multimeter in the 1920's. The original multimeter could measure volts, amperes and ohms.
What is the common use for a multimeter?
A multimeter is used to measure various properties of electricity. The "multi" refers to it multiple functions which can range from volt meter, current meter, resistance meter. The most common use would depend on the users preference to what is needed and measured most frequently.
A circuit must be physically interrupted to measure?
This is a tough question to answer because you've forgotten to include WHAT electrical property you're trying to measure. If you are trying to measure current through a closed, complete circuit with a multimeter, then yes. You must physically disconnect the circuit at the point you wish to measure, and then re-complete the circuit by connecting the leads of your multimeter to the points you just disconnected. (Please be sure the circuit is not energized before you disconnect the circuit!) If you are trying to measure a voltage difference, then no. Just place the leads of your multimeter on the two points you wish to measure the voltage between. As always when dealing with electricity, its safety first. Please do everything you can to protect yourself from electrical shock, especially if you're dealing with 120V/240V line voltages in a house.

How do you know when a wire has current flowing through it?
You can measure with a multimeter. Alternately, you can check for a magnetic field around the wire.You can measure with a multimeter.

What is the difference of volmeter and multimeter?
A volt meter can only measure voltage. A multimeter can measure other items such as resistance and continuity.
What else can a multimeter measure?
current.
Why does your 120 outlet measure 49 volts when you test it with a multimeter?
Either the supply or the multimeter is faulty.
How do you measure life in a battery?
by using a multimeter.
How is an multimeter connected to take a measure?
Multimetres are generaly used to measure the following quantities. Voltage: multimeter is connected in parallel with the Load; Current: multimeter is connected in series with Load; Resistance: the resistor must be taken out of the circuit first, then, the probes from the multimeter are connected across the resistor,
Unit used to measure the magnitude of current?
Ammeter. Will read in Amps or milliamps.
What is an input device used to measure variables?
multimeter
What should the multimeter be set on to measure charge?
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
Besides voltage and resistance what else can your multimeter measure?
current
