User manual for the NBCHAO Q/SGKW 15 viscosity‑temperature control integrated machine, covering specifications, installation, operation and maintenance.
The NBCHAO Q/SGKW 15 integrates viscosity measurement and precise temperature control in a single unit. It uses a small‑sample adapter and interchangeable SC4 rotors to measure viscosity over a wide range with sample volumes of 2‑16 ml. Temperature is controlled by a semiconductor‑based controller with ±0.1 °C accuracy, and the system is operated via the DV‑T2 data acquisition and program‑controlled analysis software.
The manual provides detailed technical specifications, step‑by‑step installation instructions, operating procedures, key function descriptions, screen navigation, and safety precautions. It also includes guidelines for selecting appropriate rotors and speeds for different viscosity ranges and for cleaning and maintaining the instrument. This manual is written in Chinese.

Use the DV‑T2 data acquisition and program‑controlled analysis software to set the temperature program before starting a measurement.
Do not immerse the rotating rotor into the sample, especially with high‑viscosity liquids, to avoid damage to the instrument.
Select a small‑volume rotor such as the 28 or 29 号 rotor and use a low speed.
