What type of measurement using a standard multimeter measuring AC voltage will the multimeter indicate?

Multimeters measure AC in two primary ways... The older style meter uses a diode, capacitor, and resistor to measure the peak voltage of the AC signal. They then compensate their calibration to read in a close approximation of what the RMS value will be. Problem is that this only works well for true sinusoidal waveforms - if the waveform is triangular, for instance, the indicated value will not match the RMS value. The newer style meter, if it states that it is a true RMS meter, will sample the input waveform and actually calculate the RMS value. This is done by adding up the squares of the input, and then taking the square root of the result. That is a much better approximation of how much power the waveform can deliver.

∙ 9y agoThe simple rectifiers in a cheap voltmeter, will generate a DC voltage, that will be presented as if it were a measurement of the RMS (Root Mean Square) value of a sine wave.
For waveforms removed from an RMS one, there is no attempt to consider the peak value, or the 'mark to space' ratio, etc.
These unusual signals are of course accurately represented on oscilloscope displays.

Can you calibrate voltmeter on multimeter or multimeter on voltmeter?
how which is right and which is wrong. You need a voltage standard with that you can calibrate both to the standard
The standard unit of eletrical resistance is?
The standard measuring unit for resistance is ohm.
What are the merits and drawbacks of using a person's foot as a standard?
The merits of a person's foot, you can use it anytime and anywhere, not unlike bringing lots of materials. But avoid your carelessness on using your foot. Because sometimes some people are not much accurate. So when they're measuring using their foot, the measurement might be not exact. Remember, even the greatest falls with this kind of measurement
What is difference between smm7 and POMI?
Standard method of measurement (smm7) & project of international management
Why a micrometer provides more positive reading than vernier calipers?
Micrometer is having a ratchet to rotate which is pre-loaded to get standard thrust while measurement, whereas in the case of a vernier the accuracy of measurement depend on the pressure each individual applying while the measurement.
What is the standard measurement used for measuring force?

Is geiger counter standard or non-standard measurement.?
A geiger counter is a measuring instrument, not a measure.

What is advantage using a standard unit in measuring?
Because it is easy to convert
Why is it important to measurements using a standard?
to make the same type of measurement around world so that there is a universal when measuring certain substances.
Is a pint a standard unit?
Yes, the pint is a defined standard unit in the imperial measurement system and the US customary system. It is used frequently for measuring the volume of beverages and food. It is not an S.I. standard unit.
What should you do if the specimen or object that you are measuring the length of is much smaller than the standard for length?
If the specimen you are trying to measure is shorter than the standard, you can use a different unit. After the measurement is completed, you can convert to the standard unit.
How can a precision of a measuring instrument be increased?
Make sure you are only measuring what you are after. Not noise and local disterbances. Proper system grounding is needed. Make sure the device you are using has been calibrated periodically properly to a N.B.S. standard. Your measurement will only be accurate to 10 times the standards value. That is a 0.3% accurate standard will only give you a 3% accuracy in your measurement.

Why do you measure using standard units instead of measuring with and kind of units?
So that when you discuss the measurement with other people,they'll know what you're talking about.
How do you measure quantities or dimensions precisely?
we answer quantities precisely by using measuring tools like rulers, and meter sticks :)
