Place the rule directly on the surface being measured, rather than at a distance from it.

Where should you position your eye in order to avoid parallax error?
It should be in the same horizontal line as the meniscus of the liquid
What are the errors in the use of thermometer?
A thermometer must be calibrated before use to avoid false readings.
What are the two precautions taken to ensure accurate results in simple pendulum experiment?
if you are conducting the experiment under a fan, switch off the fan to avoid your pendulum bob to swing in different degree. #stainless
How can a person avoid polarization?
One can avoid polarization by using positive language in order to reach a compromise. You should also try to avoid using absolutes in your language.
In measuring height which is more accurate to use the meter stick or the tape measure?
Used correctly, they can be equally accurate. Each may be better in a particular circumstance. The error in a series of measurements increases the more measurements need to be taken. So, for instance, in order to measure a 100 meter tall building with a meter stick 100 measurements must be taken. With a 50 meter measure only two measurements are taken. If the margin of error in all measurements are equal, the error using the meter stick will be about 7 times more than the error using the measure. (Why 50 times as many measurements gives only 7 times the error is the subject of another answer.) On the other hand, when measuring the overall length of an irregular object it is useful to have a rigid meterstick in order to avoid the tendency to follow the object's contour. It is best, as always, to use the right tool for the job.
Why should you avoid parallax?
There is no such way to avoid parallax error, you just have to be careful.. :)
What sources of errors are there in a titration experiment?
1 solutions may contain impurities 2 take readings at eye level to avoid parallax errors 3 incorrect volume measurements made by the experimenter
What is the function of mirror in ammeter?
That's great I have learned something new
What is the precaution to take when using measuring cylinder?
prevent trapping of air bubbles line of sight must be perpendicular to get the correct reading and avoid errors

Write the precautions to be taken while using meter scale?
Following are some precautions to be taken while measuring length with the help of a metre scale: Scale must be placed in contact with the object along its length. Eyes must be exactly perpendicular to the point where the measurement is to be taken, to avoid parallax error. If the ends of a scale are broken/damaged we should avoid taking measurements from the end. Instead, we should place the object on any other fully visible mark on the scale (say, on 2 cm instead of 0). Then you must subtract the reading on this mark from the reading at the other end.
When land surveying how is parallax corrected?
Parallax in land surveying is corrected by ensuring that the line of sight through the telescope is parallel to the horizontal cross-hairs or line of collimation. This can be done by adjusting the focusing knob until the image is sharp, and by maintaining a consistent viewing position. By minimizing parallax error, surveyors can obtain accurate measurements and avoid distortions in their readings.
Why 4 and 6 markings absent in Williams probe?
1. to avoid parallax error 2. to easily distinguish between shallow and deep pockets
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.
How does the parallax error affect your measurements?
Parallax error is the most common source of both systematic and instantaneous anomaly in experiments involving analogue measurement and great care should be taken to avoid it when recording data, supported also by repetition of each independent variable data collection stage.

What are parallax errors in a scale?
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.
