What digital multi meter setting should be used to measure voltage?

There are settings for AC and DC voltages. If they are not marked as such, the DC setting might be parallel lines and the AC marking may be a cycle of a sine wave (Wavy line).

Why when I Check ohms from ground to both 220v legs do I get a reading of 18 to 21?
With the power off? If you are looking at transformer terminals on an unpowered unit you would be seeing the coil resistance. You should not use your meter in the ohms setting with voltage present. It wasn't designed for that. Measure voltage from ground on a 220vac transformer and get 110 vac. on each side.
On a standard three prong AC outlet what should the AC voltage measure between neutral and ground?
Zero, or very close to it. If there is a large neutral current flowing, voltage drop on the neutral leg could cause a volt or so to read between the two. If you read full line voltage, the outlet is wired wrong!
How do you measure the resistance of a motor?
we can measure the resistance of the motor by using voltmeter ammeter method of by directly using a multimeter across the armature terminals of the motor in voltmeter ammeter method we should use a less value of dc voltage to find the resistance
How voltmeter works?
It is connected in parallel and measures potential difference.
Multimeter that can measure inductance capacitance frequency voltage current and resistance in one system?
Many mutlimeters have this capability. You'll probably want a digital multimeter. If you do a good search, this should be easy to find. You'll need to read through the specifications carefully to make sure you find one that gives the level of accuracy you're looking for. the more accurate it is, the more you'll pay.
In the unknown of measuring the voltage what should be the setting of VOM selector?
Use the highest available voltage setting. One should know the system voltage before attempting to measure, other wise it may lead to accidents.
Which mode is use in digital multimeter for testing of diode?
A: For a digital meter to test a diode it must have a scale for resistance for it to work, If not a 1.25 v cell with series limiting resistor will work. If you measure across the diode the reading should be .7 volts reverse the cell polarity then the diode voltage should be 1.25 v .7v is forward voltage 1.25 is reverse voltage.
Which warming blanket has a specific temperature setting?
You should get the warming blankets at Target with the digital temperature setting.
How should a voltmeter be connected to measure voltage of a component?
Since voltage is electrical potential difference, to measure the voltage across a component, you place the voltmeter across, or in parallel with, the component.
If you make a mistake in polarity when meauring the value of dc voltage in a circuit with a digital vom what will happen?
absolutely nothing happens...just reverse the probes of multimeter & measure it again...this time around it should come positive...
How do you know electrical is grounded?
I test it with a digital multimeter. Set it to measure the voltage you're expecting, verify that the circuit is powered (put the red probe to the positive side of the circuit, and find a different ground), then move the black probe to the intended ground. You should be reading the voltage you're expecting if the ground is good.
When measuring voltage how should test probes be connected?
First connect the positive terminal of the voltage line to positive terminal of multimeter and negative to negative terminal of multimeter. Select voltage in multimeter and measure the voltage
What do you use to measure the mass of things?
You should use a top pan balance or a digital balance.
Which is the correct voltage division setting for testing a throttle position sensor?
Volt meter should be in a 5 volt scale.
How do you measure the current and voltage in high tension line?
To measure high voltage use suitable instrument transformer (potential transformer) Very carefully. It can kill you. The higher the voltage the more the danger or arcing over even when two conductors are not touching. Voltage meters are rated and the rating should not be exceeded. Depending on the voltage you will need the proper meter and a high voltage probe rated for the voltage you are measuring. If you don't know what you are doing, don't mess with high voltage. Leave to the pros.
When measuring an unknown value of voltage the meter should be initially set to?
With an unknown voltage you should start out with the highest voltage setting on the meter. Doing this reduces the risk of "pegging" out the needle on an analog gauge or overloading the input of a DMM. Most DMM's are auto-ranging though.
