On October 7, 2026, we released firmware Ver. 2.1.1 for the Eccentricity Detection Stabilizer ES-001 / ES-002. You can update the unit yourself from a web browser on your computer; no app installation is required.

What’s new

• German and Simplified Chinese added as display languages (four languages in total, with Japanese and English)
• Continuous battery life extended by about 20%; fixed an issue where the unit could fail to start with a low battery
• Eccentricity below 10 µm is now shown as “<10”, since values in that range are close to the measurement limit and do not settle reliably
• Refreshed screen design with smoother screen transitions
