Unmatchable Calibration Performance at Yokogawa

Calibration systems at European Yokogawa laboratory ensures calibration performance across an exceptional wide range of condition

In today’s landscape of power electronics and energy-efficient systems, clean sine waves have become a thing of the past. Distorted waveforms full of harmonics, fast switching edges, and reactive behavior are the new normal. And that means one thing: power measurement is more complex than ever.

Accurate measurement of these non-sinusoidal signals is not just difficult – it requires a fundamentally different approach to calibration. At Yokogawa Test & Measurement, we’ve developed a method that goes far beyond conventional calibration procedures, making our Amersfoort laboratory one of the very few places in the world capable of performing fully traceable calibration on distorted waveforms.

Why does this matter?

As engineers push the limits of performance and efficiency, small differences in measurement matter more. Ten years ago, a 10% margin of error might have been acceptable. Today, system efficiency gains often hinge on changes of less than 1%. Without a properly calibrated power meter that can handle distortion and high frequencies, your measurements may not reflect reality, and your decisions may be based on incorrect assumptions.

What makes our power calibration method unique? 

Our calibration system includes up to 370 calibration points per element, verifying performance across an exceptionally wide range of conditions. The method is built around the following key elements:

• ✅ Gain calibration (Voltage & Current) from DC to high-frequency AC
• ✅ Linearity verification for voltage, current, and power – both DC and AC
• ✅ Power calibration at Power Factor 1 (amplitude response) and Power Factor 0 (phase response, including inductive and capacitive loads)
• ✅ Harmonic analysis function calibration using PLL synchronization – covering voltage, current, and power
• ✅ Time base calibration to ensure frequency measurements remain precise

This approach ensures accuracy, not only under ideal conditions, but also when your waveforms are challenging which is increasingly the case across industries like EV development, renewable energy, semiconductors, and motor control.

Trusted, proven, and rare

This is not theoretical. Our calibration methods are traceable, proven, and validated, built on international metrology principles. Yet very few labs can offer this level of calibration – and among commercial labs, we might be the only one in the world doing it at this scale.

It’s no surprise that customers from all over the world send their equipment to our state-of-the-art calibration lab in the Netherlands, trusting us with the precision that their work demands. Because when measurement matters, it pays to go to the experts.
