When making some kind of scientific measurement, it is necessary to first check your measuring instrument for 'zero error'. The zero error is the reading displayed when you know the true reading should be exactly zero.

in order to avoid zero error you must make sure that accuracy is where it should be.

for example, extremely accurate scales, may say that the weight is 0.023g, because it is weighing the air pressure as well. you must make sure it is set to 0 (i think its the "tare" button) before putting anything on it.

i really hope this helps, because i bumped into this problem before!!

Impossible. All experiments have intrinsic measurement uncertainty due to the accuracy of the instruments. For highly accurate quantum mechanics experiments the dominant error is from the uncertainty principal and, no matter how accurately you can make measurements, the uncertainty principal means that 100% accuracy of information about a system is prohibited.

In other word, zero error would violate Heisenburg's uncertainty principal. For this reason, it is totally impossible.

PS: Any number divided by zero is undefined as it is an asymptote. It is not zero and it is not infinity as, technically, this number lies completely in both the real plane and the imaginary plane, so that it exists in neither (i.e. it is a non-number).

The instruments we use in our experimental works in laboratory may become inaccurate in their initial readings because of long use or handling or may even be so since manufactured. This error is called zero error of the instrument. This error may be positive or negative. Example, suppose you are using a vernier callipers. It gives an initial reading of 0.5mm. Then it has a positive error of 0.5mm and we have to subtract this amount n all our measurements.

Probably what you are referring to is the 'divide by zero' error. Since any number divided by Zero is Zero, this can cause a problem.

its when experimental results exactly match theoretical results, it never happens
