WebFor the measurement of any physical quantity two types of errors are observed. (I) Systematic errors and. (2) Random errors. Here briefly describe on Systematic errors. Systematic errors: While performing experiments due to some errors experimental value of the measured quantity always and systematically becomes either less or more than the ... WebErrors Due To Calibration: Any instrument has to be calibrated before it is put to use. Calibration is a process of giving a known input to the measurement system and taking necessary actions to see that the output of the measurement system matches with its input.

When the jaws are closed, the vernier zero mark coincides with the zero mark on its fixed main scale. Before taking any reading it is good practice to close the jaws or faces of the instrument to make sure that the reading is zero. If it is not, then note the reading. This reading is called “zero error”. bracken beacons
