Overview & Background
Backed by over 20 years of expertise in high-reliability embedded systems and modern IoT control, Beijing YiLink Technology presents a comprehensive automated calibration solution integrating full-spectrum hardware standards, the yiCali browser-based automated calibration software, and the Cloud Cali digital management platform. Designed to eliminate manual logging, error-prone calculations, and paper-based tracking, the solution leverages native Web Serial and Web Bluetooth technologies to achieve driver-free cross-platform communication. On-site engineers seamlessly interconnect tested instruments (Modbus) with reference standards (such as Pro8C wireless standard platinum resistance thermometers). From work-order management, batch setpoint planning, and intelligent thermal equilibrium detection with anti-instability countdowns, to proprietary three-step deviation correction (clear old data -> write correction table -> readback verification), JJF 1309-2011 automated fluctuation evaluations, and one-click A4 PDF certificate generation with digital signatures, the system connects directly to the cloud platform for multi-device supervisory monitoring and complete digital traceability. This establishes an all-in-one "End (Hardware Standards) + Edge (Automated Testing Loop) + Cloud (Collaborative Metrology Hub)" cloud calibration ecosystem.
Pain Points in Traditional Calibration & Manual Testing
- Tedious and error-prone manual operations: Conventional verification requires manual reading, formula calculation, and handwritten reports, leading to inevitable human transcription errors;
- Subjective equilibrium judgment: Assessing thermal stabilization by sight lacks objective criteria, causing premature or delayed sampling and compromising accuracy;
- Disjointed calibration and parameter adjustment: Calculated deviations must be manually keyed into instrument registers one by one, lacking closed-loop readback verification;
- Heavy software dependencies and driver installation: Traditional calibration programs require dedicated desktop operating systems, proprietary drivers, and dongles that frequently trigger COM port conflicts;
- Isolated standalone equipment and fragmented data: Calibration baths operate offline without cloud-based fleet monitoring, standardized dispatch, or lifecycle traceability.
Core Solution Advantages & Capabilities
