An error can be classified into three types: Gross error, Systematic error and random error.
1. Gross error: this class of error mainly cover a human mistake in reading instruments and calculating measurement results.
2. Systematic error: The systematic error can be classified into three type’s Instrumental error environmental error and observation error.
Instrumental error:
- Error due to improper zero adjustment
- Due to inherent shortcomings of the instruments
- Due to the misuse of the instruments
- Due to the loading effect
Environmental error: These errors are due to environmental factors like change in humidity, temperature and variation in pressure.
Observation error: These errors are induced only by the observer and most common error is parallax error. These parallax errors are introduced while reading a meter scale.
3. Random error: These errors are due to small factors which changes very often from instrument to the other instrument. These errors are also due to unknown cases which are also called residual error

Error due to improper zero adjustment
Improper zero adjustment is classified as Instrument error.
Explanation:
- When the zero adjustment on an instrument is not set properly, it can result in errors in the measurement readings.
- This type of error is considered an instrument error because it is directly related to the calibration and adjustment of the measuring instrument itself.
- Improper zero adjustment can lead to inaccuracies in the measurements taken by the instrument, affecting the overall reliability of the data collected.
- It is important for operators to ensure that the zero adjustment is correctly set before taking any measurements to minimize the risk of errors due to improper zero adjustment.
Therefore, error due to improper zero adjustment is classified as an Instrument error in the field of electrical engineering.
