What is the use of the measurement range in a multimeter?
With today's auto-ranging meters, you might well ask why. Today meters do that for you, and you might see it happening on some of them. In older meters, analog types in particular, you had to start with a higher range to be sure you didn't peg the meter measuring say, 220 volts when on the 10 volt scale. Lots of meters where toasted this way, their needles bent, or fuses blown by overcurrent. On higher ranges, the meter would deflect slightly, indicating there was voltage there, but not enough to get a accurate reading. So you scale down until hopefully you get a reading somewhere in mid scale, where the most accurate reading can be made. So the use was to protect the meter from damage, and provide the most accurate reading possible from an analog meter.
Current and voltage readings taken on the far right of a meters scale provide greater?
Current and voltage readings taken on the far right of a meter's scale provide greater inaccuracy that readings taken from mid scale on the meter.
Need to convert a two wire 0 to 15 volt dc analog panel meter to read 0 to 30 volt dc how can I do this and what parts will I need?
PUT A MULTIPLIER RESISTOR IN SERIES WITH THE METER AND SOURCE. RESEARCH 'METER SHUNTS AND MULTIPLIER CIRCUITS', IT TAKES ONLY ONE SMALL RESISTOR.....(OR IF YOU HAVE EXTRA METERS, PUT TWO OF THEM IN SERIES WITH THE LOAD AND SOURCE; THEN ADD THE TWO METER READINGS.)
How is the voltage measureing range of the basic analog meter movement extended?
shunt resistances are used to increase the range of ammetes and moreover it is praticularly then we have to low value shunt resistance.
What are the disadvantages of a digital multimeter?
An analog meter will respond to linearly as current is present . digital meters cannot do that not until the conversion is complete. in essence an analog meter is human friendly as compared to a digital meter. both have their places in applications.
How parallax introduces errors in reading analog meters?
You get parallax errors with analogue meters if you don't align your eye so that it is perpendicular to the pointer. When this happens the pointer can appear to line up with the wrong mark on the scale. The further your point of view is away from the perpendicular, the greater the error. The potential for errors can be reduced by minimizing the gap between the pointer and the scale or better still fitting a mirror behind the pointer so that it is in the same plane as the scale. The mirror assists the viewer find the correct point of view, since in this condition (correct point of view) the reflection of the pointer will be hidden behind the pointer.

How much error is acceptable in analog PF meter?
Old type, analog power factor meters may be considered 2% instruments.

three-point distance to 6.75 meters

Why is a pulsing voltage easiest to read on an analog meter?
This is because digital meters do not continuously update the display. My meter for instance only shows a new number twice a second. If the voltage peaks between updates, you will never see it. Analog meters continuously follow the voltage, and the eye can follow the pointer as it peaks. Many electricians and technicans still hang on to their beloved Simpson 260 analog meter for this very reason. Many digital meters now have a little bargraph below the main display, set to act like an analog meter, to make this type of visual measurement possible. It should be noted that even the analog meter does not respond perfectly to voltages that change quickly, because the physical mass of the meter movement cannot accelerate insantaneously. So, if you see the needle "pulse", you know there was one, but you cannot rely on the needle to show the true peak. Such measurements are used to see the trend or get a rough idea of what is happening in the circuit. If you need to find the exact value, use an oscilloscope!
What do most analog meters use to facilitate the needle movement?
a magnetic field that is produced by flowing electrons

What does nm mean on a laser pointer?
nm is nano-meters. There will be a number preceding the nm. This number indicates how many nano-meters for a full wave length of the laser light.
