What is instrumental (constant) error?
✓

Answer

Instrumental error:
  1. It arises due to defective calibration of an instrument.
  2. Example: If a thermometer is not graduated properly, i.e., one degree on the thermometer actually corresponds to 0.99°, the temperature measured by such a thermometer will differ from its value by a constant amount.
