Reliability of Kinovea Software for Ergonomic Analysis Calibrated Using Cost-Effective Equipment

When the measurable quantities are not given a value for the amount considered or found a standard for the quantity, it requires calibra-tion. Calibration is a preparation process before starting the test. It is a process of finding the relationship between two unknown quanti-ties. If one of the quantities is known because it is made or set with another device, another measurement is made as similar way as possible with the first device using a second device. The measurable quantities may differ in two devices which are equivalent. The de-vice with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument or any of several other names for the device calibrated. [1] The process can reduce the error margin of the tested measurement and that will prevent any unnecessary problems that may harm human in certain application applied.
