1.) Turn all the power in the circuit off. 2.) In volts mode (both AC and DC) check to make sure there is no power. 3.) In ohms mode check to see if the resistance is close to zero. (Check zero by connecting the leads together momentarily.) Note that light bulbs will have far less resistance cold than when hot, due to their negative temperature coefficient, so you should remove them, and that Transformers and motors will appear to have zero ohms due to their inductive reactance, so they will also need to be pulled from the circuit.

How do you find shorts and opens in an electrical circuit in multimeter?
An open circuit essentially has an infinite resistance. It is shown on digital multimeter as OL. (Open Line) A short circuit should read zero, or nearly zero, depending on the accuracy of the meter.
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
Why is it harder to measure amperage than voltage whit a digital multimeter?
Because to measure amperage you must connect the multimeter in series , in order to do so the circuit must be broken first. In the case with voltage measurements the multimeter probes must be connected in parallel which is far easier because connecting the multimeter this way the circuit will remain intact.
What is the name of the device that measures resistance?
Most multimeter are able to measure resistance.
What purpose might the multimeter serve in maintaining and troobleshooting a computer network?
With the multimeter you can measure the voltage on parts of the circuit board. You can also measure the resistance of resistors and make sure there are no short circuits in the circuit.

How do you test that inverter battery is exhausted or need to be replaced?
Use a multimeter to measure the voltage.
Can you use the multimeter to measure the resistance of a resistor when there is current passing the resistor?
A: NO the only way is to lift one lead and measure.
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 tool can you use to troubleshoot power supply issues measure current resistance or voltage?
multimeter
How and what is a multimeter use for?
a VOM is typically used to measure resistance, potential (voltage) and current (amps).
What else can a multimeter measure?
current.
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.
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.
