Learn how to avoid parallax errors and correct zero errors when measuring with different instruments. Find definitions, examples, worked problems and more on this topic.
A zero error occurs when an instrument gives a non-zero reading when it should actually read zero. For instance, if a weighing scale shows a reading of 50 grams when nothing is on it, it has a zero error of 50 grams.
Learn how to identify and correct zero error in an electronic pressure transmitter using a 5-step up-and-down calibration test. See graphs, equations, and examples of zero error and other instrument errors.
Neglecting Zero Error: Mistake: Neglecting to account for zero errors in the calibration of the Vernier caliper. Troubleshooting: Regularly check for zero errors by closing the jaws without any object in between. The zero on the Vernier scale should align precisely with the zero on the main scale.

May 2, 2023 · Due to mechanical errors, sometimes the zero mark of the vernier scale does not coincide with the zero mark of the main scale, the vernier callipers is said to have zero error. It is determined by measuring the distance between the zero mark of the main scale and the zero mark of the vernier scale.
