Best Answer

When a readng is taken from an analog meter, the pinter must be viewed correctly as it is a short distance away from the scale, so if read from one side, an error of several divisions will occur. To avoid this error the meter should be read from a position directly above the pointer. To help avoid this error most meters have a mirror in the scale so that the error may be dicerned more readily.

Why are parallax errors considered systematic errors?

simply speaking, systematic errors are those you can improve on( so if you have a systematic error, its probably your fault). Random errors are unpredictable and cannot be corrected. A parallax error can be corrected by you and if there is a parallax error, its probably your fault.


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.


What are the types of random error?

Random errors can be parallax and from changes in the environment.


How parallax can be avoided?

To help the user avoid this problem, the scale is sometimes printed above a narrow strip of mirror, and the user positions his eye so that the pointer obscures its own reflection. This guarantees that the user's line of sight is perpendicular to the mirror and therefore to the scale. Parallax is thus avoided.

parral error should be avoided cause it can cause a disaster


How does a digital multimeter eliminate parallax error?

When reading the needle on an analog meter, you can get a slightly different reading depending on the position of your eye relative to the needle and the scale behind the needle. This is parallax. The digital meter reads the exact value measured (to the accuracy of the meter), and then displays it in the form of "numbers" or "digits" so your eye is not interpreting the value from a scale.
