Is it always better to take measurements with the most accurate instruments available?

Yes and NO,
NO - there is no such this as 'The Most Accurate' because these machines holding the name are upgraded and fixed on a regular basis and all machines can go wrong.
Yes - They are more detailed and will work better than older versions. e.g A earthquake predictor now shows tremor lines on paper, before that the Chinese has a statue with metal spheres in its mouth and was only good when there was an actual earthquake happening.
I hope this answer has been of much use.

It means that there are always opportunities available for you, even if they do not appear like it.

Why moving iron is used in both AC and DC current?
A moving iron instrument works by means of a coil that attracts a moving iron mass that is attached to a pivoted pointer which moves across a graduated scale. The iron mass will be attracted towards the coil, regardless of the magnetic polarity of the coil. So, as an AC current continually reverses the magnetic polarity of the coil, the iron mass is always attracted towards the coil, never repelled by it. Similarly, a moving iron instrument doesn't care in which direction a DC current is flowing. So the instrument works equally well with both AC and DC currents. Moving iron instruments, however, are not as accurate as moving coil instruments which, of course, are sensitive to the direction of current.
Can you describe shielding and grounding for electronic instrumentation?
The purpose of shielding is to reduce or eliminate noise currents from coupling into electrical measurements. It surrounds the electrostatic shield, protecting the instrument user from hazardous voltages. Instrumentation is safety grounded at the power inlet, ensuring that the metal instrument enclosure is always safe to touch.
Is sizeof an operator or function why?
You cannot overload the sizeof() operator because that could introduce uncertainty in its evaluation. The sizeof() operator must always produce an accurate and logically predictable result, thus all user-intervention is completely forbidden.
Are precise measurements always accurate?
No. A broken clock gives a very precise time, but most of the time it is wrong.
Measurements made by hand are more accurate than those made by machine?
The measurements are almost always correct when made by machines. An example would be a calculator.
Why is it necessary to calibrate a thermometer and volumetric?
In order to get a more precise and accurate reading.
What are the instrument used to determine your weather?
You could watch TV on the weather channel to get a forecast. However, you can use a weather station to determine your current weather, careful though, some instruments are inaccurate. In order to get accurate measurements, always follow the instructions included with your weather station.
What is a measurment closee to the true size?
Accuracy
How do you decide calibration frequency for instruments?
Normally it will get from its instruction manual. In most of the engineering concerns there will have a calibration schedule for calibration of measuring instruments. The frequency of calibration mainly depend on the type nature and usage of such instruments.
Can corresponding angles have the same measurements?
Yes they always do have the same degree of measurements
When is a measurment accurate?
Never: A measurement made is always an approximation. We can get very close to being accurate with our measurements, but never fully 100% accurate. This is not the fault of the person measuring, or what tool they are using to measure with, but it is a natural law that we (anyone, even superior aliens to humans) cannot ever fully make an absolutely accurate measurement.
When did measurements start?
Measurements are probably as old as mankind.People have always needed to measure something.
Accuracy of Internet Information?
Although there is plenty of accurate information available on the Internet, you need to be careful. There are plenty of websites that appear to be accurate, but are not. You should always research any information you find on the Internet to ensure its accuracy.
Are hospital pregnancy test always accurate?
No , they are about 99% accurate :)
Is wave always available?
wave is not always available becuase wind is not always available
