Define the Problem

A measurement system exhibited noticeable variation between manufactured units, reducing confidence in reported data.

Diagnose the Root Cause

Component tolerances and analogue variation introduced differences in sensor response across production devices.

Key engineering challenges included:

• Production variation

• Sensor non-linearity

• Maintaining manufacturing efficiency

• Accuracy requirements

Deliver the Solution

We implemented a multi-point calibration process combined with firmware compensation algorithms to normalise behaviour across devices.

Key Outcomes

• Improved measurement accuracy

• Increased unit-to-unit consistency

• Reduced calibration drift

• Improved product quality
