Verify that the device provides the same output for the same input multiple times.
The full title of the standard is “Process measurement and control devices - General methods and procedures for evaluating performance - Part 2: Tests under reference conditions.”
The standard requires a series of "calibration cycles." Typically, this involves increasing the input signal in steps (e.g., 0%, 25%, 50%, 75%, 100%) and then decreasing it back to zero. This reveals: How closely the output follows a straight line.
While Part 1 of the series covers general considerations, provides the "how-to" for conducting tests. It defines the specific procedures to determine how an instrument performs when environmental and operational factors (like temperature, humidity, and power supply) are kept at a constant, "ideal" state. The Importance of Reference Conditions
To provide standardized data sheets that customers can trust.
IEC 61298-2 outlines several rigorous testing cycles. The most critical include: 1. Accuracy and Hysteresis Tests
