1 Answer

Answer :

Systematic Error:

i) Instrumental Error: These errors are caused due to the mechanical structure of measuring instrument such as:

a) Inherent shortcomings of instruments: Instrument may read too low or too high.

b) Improper use of instruments: Improper handling e.g. overloading, overheating, failure to adjust zero, use of high resistance leads.

c) Loading effect: Cause distortion in original signal.


ii) Environmental Error: These are because of surrounding conditions such as temperature, pressure, humidity, dust, vibrations, or external magnetic fields or electrostatic fields.


iii) Observational Error: Parallax errors, incorrect multiplying factor.
