Determine the intrinsic error of the device.

The difference in output at the same input point depending on whether you are "going up" or "coming down" the scale. 2. Dead Band Testing

To verify that the equipment they have purchased meets the technical specifications required for their specific process.

Before you can understand how an instrument fails or drifts in extreme heat or vibration, you must first establish its "baseline." Testing under allows engineers to:

Whether you are a manufacturer testing a new pressure transmitter or an engineer validating a control loop, understanding this standard is essential for ensuring operational excellence. What is IEC 61298-2?

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.”

This procedure measures the smallest change in input signal that results in a measurable change in output. For high-precision control, a low dead band is vital. 3. Repeatability and Reproducibility

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.

IEC 61298-2 isn't just about static accuracy; it's about timing. These tests evaluate how quickly a device responds to a sudden change in input (Step Response) and how it handles oscillating signals (Frequency Response). Who Should Follow IEC 61298-2?

IEC 61298-2 outlines several rigorous testing cycles. The most critical include: 1. Accuracy and Hysteresis Tests
